Is a $2500 MK8R Golf R Exhaust Worth? ~ Power and Sound Test
ฝัง
- เผยแพร่เมื่อ 4 มี.ค. 2022
- Today we install a MK8r Golf R exhaust. Installing a MK8 golf R exhaust or MK8 GTI exhaust is an easy DIY. We also baseline dyno the mk8 Golf R to see how much horsepower the Golf R makes. Then we install the MK8 R cat back exhaust, and head back to the dyno to see how much power we gain from the exhaust. #humblemechanic #mk8R

I picked this exhaust up from BMP Tuning(link in description) before the car even landed. Next mod coming will be Power Fold Mirrors, first oil change with oil analysis, then we have a TON of parts to test fit. That should be fun times!
Appreciate it again, Im really shocked that the factory Golf R system weighs less than the Milltek - I know on the GTI system when we weighed them, it was identical in weight (but we made power + sound was amazing).
Great video as always and happy we could assist with your mod bug!
Love your channel and videos but sometimes I don't get notifications
@@ragnarironspear1791 :( Im sorry about that. TH-cam is weird.. plus you have to have YT notifications on AND them on for you phone or it mayn't get them
@@BMPTuning The weight thing threw me. I have never had that happen.
@@HumbleMechanic No need for you to apologize it's not your fault . I've had it happen with other channels like Goon Squad and the likes
Thanks for taking the $2500 hit so that nobody else does. The hero we didn't deserve
Seems like $2500 for exhaust tips. I highly appreciate you for doing this video and all the testing/installation.
Agreed. Literally no benefits.
Agreed. What a waste. And the single walled tips aren't all that either.
And it weighs more than stock
We're lucky to have Charles test it all out for us so we know what we are getting in to.
Yep, agree with you guys, $2500 for what. And the dam thing is heavier, thank Charles for the test
Are you sure the R didn’t go into low emission mode when it realised the rear wheels weren’t rotating🤣🤣🤣🤣🤣
LOL Okay, so in general I hate the TDI nonsense references... But that one was funny. ;)
Stock exhausts systems have come a lonnnnnng way!!! $2500 for a cat back is insane for zero performance.
That was my big takeaway. The stock on is really well dialed in!
Kinda like cold air intakes were years and years ago (and still are). Lots of money, but no gain, once manufacturers started adding intake hoses and not just running a snout off the air filter... even my 1984 F150 has a stock cold air intake!
Doesnt surprise me. Thats what I tell people all the time: Cars nowerdays are so refined and optimized for performance and emissions. VW spends billions on R&D and theres litterally 100s of engineers working at VW to make the perfect exhaust system. Its funny that people think some aftermarked company slapping together pipes would exceed what the VW engineers did.
Imho you buy aftermarket exhausts for the looks and because theyre sometimes louder. But expect a slight performance dip (especially on NA cars), not a performance gain.
On an R spec I would think all tweaking would of been factory done. On a "normal" car I'd expect to see an improvement and that's where the difference is.
@@bryce1274 Nope.
Because all cars (also "normal" ones) are maxed out to be highly efficient (for fuel consumption and emissions) and generate as much power as possible from small displacements.
We're not living in the 80s anymore, mate.
I don't understand how exhaust companies can still claim hp/tq increases nowadays, these eCU are smart enough to keep things within oem parameters.
Well with VW's semi recent emissions history, whats OEM parameters? Lol. But yeah I'm curious as well, how did they get a 25hp claim from the exhaust?
@@johnnyringo4463 crazy to think how much time has passed since that happened.. anyway, I really only expect gains from a downpipe and maybe the catback can give you a few ponies when paired with a downpipe. On the stock downpipe though? I don’t expect any gains, but I’ve seen some more more power on the stock downpipe with a different catback
The benefit is likely if you are going to get it tuned. The stock exhaust will hit a power wall before the aftermarket exhaust, plus getting the cats and dump pipes upgraded would add further - when tuned
Shows how well VW have the stock one sorted . Interesting video though.
When you revved it up with the exhaust removed, and it didn't get noticeably louder, I knew you weren't going to gain anything from the new catback. These modern turbos are just so efficient at sucking up exhaust gases and turning em into boost.
I was going to suggest maybe a stock exhaust resonator delete, but I see it doesn't have one.
more like the ppf kills the noise. my 2018 leon cupra which shares almost the same engine as this car sounds louder with just the resonator removed than this mk8 missing the backbox and resonator lol
@@Regape96 Maybe. I've never owned a car with a ppf. However I do own the original 2004 R32 which has an incredible sounding stock exhaust (loud enough that random Karens would shout at me when I was driving down the street at the speed limit), and when I put a turbo on it, it became incredibly quiet. Hitting the gas made it go from "angry wookie" to just an annoying soft whoosh. So quiet that I lost all enjoyment in the car at less than 10/10ths and almost got rid of the turbo. I finally found a much more free flowing cat back exhaust with a nice tone, but it's still quieter than stock.
It was awesome meeting you yesterday! It’s amazing how similar car brands are at the core and how the manufacturer handles the end product that the tech sees. Thank you for the chat
I'm so glad somebody is doing us all a service by warning us not to buy an expensive piece of garbage. Thank you Charles!
Really happy someone actually made such an effort to test different scenarios. Tnx for the effort!
Thanks for doing the testing, sad to see they are charging $2500 for no HP gain with the additional 20 lb in weight.
Appreciate the review. It really is amazing how well VW did on the factory exhaust. I guess this just saved me some money.
Have this catback on my 7R and love it. Running their Road+ resonator but I also have their non-resonated and standard resonated mid pipe. Found the Road+ to be a nice sweet spot between the factory-quiet normal resonated and the droney non-resonated. I'm also running an IE downpipe which makes it far louder than with the factory downpipe.
I fitted a Millteck cat back exhaust to my Mk 5 GTI , found it to quite so I removed the system and taken out the massive amount of Fiber glass padding from the resonator and the big muffler, welded the both shut and reinstalled the system . Sounds awesome now and not to loud . With the system fitted with large muffler and resonator the car sounds has a more of a deeper sound . Sounds like more of a 2.8 L engine then a 2.0 L . Later I taken out the secondary cat from the system and sounds even better . Very happy now with the sound with no drone . Cheers bearded wonder 👍keep knocking out your great video’s , great job 👏
Yeah I like the non res Milltek exhaust sound the best especially when he does the drive bye it sounds very free flowing and good.
Charles out here saving us money left and right! I was surprised to hear such a small difference in resonated vs non-resonated. On the MK7 I added an aftermarket resonator after going stage 2 as the highway drone was too much for me to handle.
*Your videos are so thorough and interesting very inspiring* 👏
Saved me some big bucks. Thanks for this Charles
Thank you for doing this. I think I will keep mine as is and maybe add a down pipe down the road once available
I Love the Miltec exhaust on my Golf R
it makes her sing soo beautifully
beautiful vid Charles!
most modern cars wont gain much of anything with just the exhaust because the engine will re-tune itself to meet certain criteria and the outcome will be nearly identical power output.
@Franz Fanon Yes. The computer is programmed to adjust (within a certain percentage range) to conditions as they are forced on it. This could be running leaner or richer or off of sub optimal fuel or at high elevation.
There are no any sensors after the cat that could detect any power differences and feedback to the ECU. And there is no built-in dyno into the engine..
@Franz Fanon ofc not. Some cars are meant to be "sporty" or modified. I am saying that most of the time your gains will be negligible if you're tryiing to mod a corolla or an elantra. If you put a mod on a car it is always good to get it tuned to use the mod to the best ability it can, so yes alot of factory exhaust can be very restrictive, and same with the air intake tubes, but if you make the mod on a car that isn't meant to be modded you'll experience way less improvement than if it was on a miata or some shitty brz that's "meant" to be modified and tries to sell itself as a sports car. Those same parameters that we were talking about the percentage up and down that the computer can account for - those are your increases in power. so expect maybe a max 3 to 5% increase after that yes the computer will de tune that shit to minimize effects on the cars reliability and standard tune.
I had the “suitcase” removed from my 2022 TTS at a local muffler shop and added some black stainless steel tips, installed it was $800. It sounds fantastic under acceleration, perhaps a bit too loud so my wife says. I just turn up the stereo when she’s in the car.
That hanger tool is awesome
Super informative, glad to see the exhaust engineers at Volkswagen are doing a great job (unlike the infotainment designers).
Thanks for making this comparison, really interesting results!
I'm curious as to how this Milltek one compares to the Akrapovic / Titanium exhaust which is a factory option for the mk7.5 (not sure if it's also on the mk8)?
Thank you for the great video!
Awesome video! Wondering your thoughts on how exhaust pipe diameter changes the volume and tone of the crackles and pops inside and outside of the car. Thanks!
Great video!!! I was surprised by the weight and NO power gain. Kudos to VW for the exhaust. Thanks for the video!!!
Thank you!! We were shocked too. I knew after driving it wouldn’t be much. But zero hp was shocking
@@HumbleMechanic starting with the Gen 2 TSI and larger motors vag products started using properly sized catbacks
I was thinking about putting a Milltek exhaust on a Cupra Formentor. But, I'm not sure now
Thanks for the amazing video mate 👍
thank u for such a great video. i always knew these expensive systems have no performance gains. its better to just remove the resonator and use stock muffler. same sound.
Looks great!
The gpf is really holding the exhaust sound and hp gains back. Can’t wait for aftermarket downpipes.
I never knew they made that exhaust hanger tool! Man that thing would have saved me countless hours. Especially in the cold when those rubber hangers get hard.
Awesome review, that took a lot of work... Looks like VW should hook you yup for that review 🤙🏼🤙🏼🤙🏼
I've always thought Milltek's stuff was highway robbery, and you proved it in this video. I'd be interested in seeing you do this with the much less expensive Neuspeed exhaust for this car.
I wonder if you'd get anything noise/performance gains from a GPF delete too? I know on the previous gen golf r gpf deletes sound absolutely stunning.
Ian is such a cool dude, I went to reflect tuning to get my 1.4 custom tuned before I sold it.
Nice
Great video dude, have you got a link for the exhaust hanger removal tool?
Good video. I picked Remus for my Cupra Ateca. It sounds so good :P
Nice exhaust man
Great video, keep 'em coming!
Web calculator gives your engine 336 at the crank, another yields 324, German marques underrate engine output, so factory estimates are valid under variable conditions. Your results don't surprise.
Seems aftermarket exhausts are about sound, which may not yield more power, some remove the cats as well (a no-go for me). After buying these exhausts for multiple $Ks owners have to believe they're effective, since you've spent the money and believe the ads! My German car cousin to yours, can be outfitted with a replacement muffler for $5k, promising similar gains. I'll leave mine alone and take driving lessons instead.
Or for that amount of money pull your engine, build it and turn up the boost. That exhaust was a joke.
You’re forgetting the US uses gasoline the we in Europe stopped using in the late 90s.
I’m running 100octane from the pump. Premium in many states of America is 87 which is hilariously low octane.
@@phillip3330 😂 what’s hilarious is that you don’t know that they are simply different ratings.
Look it up, they are rated differently, it’s not that the fuel is of a higher octane. You can rate the US fuel and get the same results. We even have pumps with 100, 104, and 110 octane in many places. Our 100 octane fuel is better than your 100 octane fuel just because of the rating.
And 87 octane isn’t premium lol, that’s the lowest octane you can get. Premium is 91-93. Not all places have 93, like California is known for having 91 octane. Regardless, you can always mix a little e85 or octane booster no matter where you live
@@phillip3330 premium is 91 or 93. 87 would be normal or midrange gas in most of the US. We can run ethanol as well if you tune for it.
@@phillip3330 You're forgetting that that fuel octane rating is measured differently. Outside of the US, fuel octane is rated either by RON or MON. US' rating is based on an average of RON and MON.
Read the small text below the octane rating at a US pump. It will show the simple math formula for calculating an average, which is simply adding multiple numbers together and dividing by the amount of numbers used. In this case, R+M / 2 aka RON + MON divided by 2.
That 100 Octane that you're using, is the US equivalent to anywhere from 91 to 95 octane.
You're the man thx!
Charles you are a rare human. Gifted and humble. As stated before not a fan of these cars. Yet cars are cars and there's a good chance I am gaining insight and learning. The preference is for sleepers. When a vehicle exhibits obnoxious behavior. Commonly referred to as fart faster 40 with burpage. My reply is this. They paided a lot of money for that and they are going slower! The video should be a PSA for the masses. The cost of this exhaust is roughly 5% of the vehicle cost. No labor cost included. As usual a great job by you Sir.
Thanks so much!!!
EPL and 034 have both said that VAG exhausts are really good now and free flowing. They said in their experience the only benefit to an aftermarket exhaust is sound.
Awesome vid, great content and presentation ... I miss the good ole days ... spent $ got + hp lol
Great video. This should help people not waste money on this exhaust. $2500 to add weight and lose power.
Thank you! It was tough because I think its a really nice unit. and it looks AWESOME. But if you are chasing power, this is not the mod. Some sounds and looks, this is the mod.
Great cars. They do basically everything but sound good. I’m getting ok with that.
Resonated race mode sounds the best imo. Added bonus, no freeway drone punishment
Great video,
You need a good downpipe to get performance avantage. also sound on stainless steel change after 2/3000kms with heat cycle.
3 more months until my MK8 R comes in. Thank you for the content 👌🏽
Its going to be worth the wait
That dyno just gives me flashbacks any time one of your videos features it now.
Lol me too. I was tense
Not worth the money but thanks for the awesome presentation. I’ve enjoyed the detailed steps and tips in the installation.
I think the resonator will have more effect once you swap out the downpipe and drop the cat. That's when I noticed the drone most was from the downpipe install.
Sounding good man! Glad you’re liking the car. See you at WITW!!! My 09 tt 3.2 6 speed will be there
Thank you!!! Im so dang ready for Wookies... My fav event of the year
Factory exhaust with new tips welded on. That's nuts 2500
Positives: Looks & Sound
Negatives: Cost, weight, open motor, no gains
Just saved a lot of money for the community.
Looking good you stud!! What solo region are you in? I may come do one over there 😁
I think downpipe is enough. Friends of mine tuned a Cayman T couple of days ago, removed OPF (downpipe and BR Performance stage 1), and it gained a lot, both performance and sound wise. However, who has money and really wants this, I'd say it's worth it.
Silicone is the "make the rubber slippery" magic!
I felt same way once i finally got exhaust hanger tool :( Should have bought this years ago lol
I genuinely think that the power increase Milltek suggest would come in to effect when it’s remapped but that’s with a sports cat.
Personally I would always go with Cobra exhausts over Milltek.
Thank you for this video.
hey man its leif from the expo in mke. thanks for showing up, it was a great time!! that one dude was kinda creepy though.
Great to see you dude!!!
My OCD? Aligning the exhaust tips would've become my summer project.
Sounds like 3 cons for this or possibly any exhaust for the car. Thanks for the information and all the hard work to put this video together.
Referencing Pitch Meetings is super easy, barely an inconvenience!
Also Tight!
notification squad, Have a nice weekend! Guys🔥🔥🔥
WOO
Nice sound but I prefer Remus performance exhaust. It has a very unique tone. Make a video on how to service our mk7/8 sunroofs.
In the cat-back area the exhaust gasses already cool down quite a bit, and it's very rare for the OEM resonators with meshes and serpentines to be a restriction for those cooling down exhaust gasses, so no power gains.
Nice comparison. Upon your comparison, I think just buying the tips is all you need :P Black looks good
Keep the resonated section when you upgrade the downpipe. And TBH that price is pretty fair for a 304ss, 2valved exhaust with 4 tips
Are the stock exhaust are this tips clamped on or welded. I feel like I might as well keep the exhaust stock I'm just not in love with the chunky tips.
Cool video Charles 👍
Would be interesting to compare a custom exhaust and Akrapovic to the Miltek pipes.
Im not sure how to get my hands on one... Or if I can really justify it.
thoughts on a cutoff valve on stock exhaust right before the resonators?
@HumbleMechanic Was this exhaust system advertised as providing horsepower/torque increase?
Didn’t waste anytime on the exhaust lol. Beard looking great!!
What are the best/worst years, reliability-wise, of both TDI jettas and golfs? Reliability is what i would equate to be both odometer high-score capacity and monetary efficiency(both mechanical reliability and mpg) between now and said odometer high-score if it comes to be.
HUGE thank you for making this video. I was about to order this exhaust for my Mk7.5. I knew there wouldn't be a power gain, but sound wise, it really is not that much better than stock. I would really be bent spending $2,500 for something this negligible.
they have a race pipe im going to be testing too. But still $2500 is a LOT of money,
Definitely going to wait to see what else comes out.
Im sure there will be a few options before too long. Everyone starts with GTI, then does R
@@HumbleMechanic I am going to say that I think the factory did a great job with tune and exhaust as is. I've got a manual and I'm getting all kinds of pops out of the stock pipes. Mad fun.
The VW City also known as Volkswagen's Factory understands the customers concept of, "The Hot Hatch" so they know the customer wants the most power it can get from the exhaust from it's engine. The technology that VW has and the amount of effort they take into their vehicles to date has been successful with learning not only from their mistakes but saved us from having to make as many changes on our quest to give more power overall. For that I thank them.
Usaly you need a tune to see any difference. Stock tune adapt to the weather to output a stable torque curve in all conditions. So for the small difference that the cat back could make, the ecu adapt the map to the desired power output. You can try adding an intercooler and a full turbo back exhaust with a sport cat (with a lamda spacer for the check engine light) to see if you gained anything. Then try with and without the same upgrades, with a tune.
Super easy, barely an inconvenience
recently ordered this setup used from Urotuning but that coupler/reducer wasnt included. do you know what the OD to ID is?
Shows you Volkswagen know what to do to make great stuff and power
Them tail pipes look massive!!
for $2500 all you got was a bigger diameter lmao
Great video. How much is stock dyno number?
We have to comment, sub, turn the bell on, click on the ads so we can offset the 2.5k hit Charles took for all the mk8 guys out there.
I also bought all stage one parts for my mk7.5 before it arrived. Yet to arrive
Love the video 👊 but tbh I think u should have fine tuned for the both miltek res and none res ,,,,. And I guess the goal is manifolds and straight through
I really dont think a tune wuld matter. But we are gonna find out soon
wow must be nice to be able to work on exhaust without any rust. like any time i do any exhaust work it's like 50% of the stuff is rotted away
ITS THE BEST!!!! LOL
@HumbleMechanic when will we see some more videos on the black R.
It would be interesting to see the air flow, boost, and throttle data. If there were gains it's likely all being taken away to maintain the factory torque demand curve. These aren't like cable throttle cars or even the 1.8t where they just adapt fueling and spark to extra air flow conditions. They only make as much torque as the driver wish requests and that's it.
Sweet vid. I don't know what my mk6 R exhaust was but I dropped $4500 for a @soulperformance exhaust for my Cayman S and it was worth every penny.
Wait up, so this exhaust adds weight to the car? The whole point of a catback is to add some sound and reduce weight since the gains are negligible. Thanks for the video and for everything you do for the community. This reaffirms my conviction that buying a catback is a waste of money, specially on the Mk8 which sounds better than before in stock form.
All you need is a catless downpipe and a tune. That's where all your power comes from. Leave the factory catback on and change the tips. Most cost effective way to increase power and sound.
good work sir
Thank you!
would you suggest anti-seize on the exhaust adapter sleeve you used with clamp? Or would the heat be an issue
I dont think id put it there.
I would like to see how it sounds with a straight pipe from the cat back with double cannons at the back without the muffler.
I bet thats gonna give some nicer sounds ^^
TT in the background! I’d love to see a video on one sometime.
Soon! Very soon
