- How's it going guys?!
I've had a lot of you ask me for a "test pipe specific" install video for the B8/B8.5 S4 Platform. Since I'm not currently installing any test pipes I went ahead and took the snippet of the install from my full exhaust video.
Since the video is a little older, and not up to our current standards I also added a quick voice over to help clear up any confusion on the job.
If you have any further question on the install, definitely let me know down in the comments, and I'd be happy to help!
Other than that, Thanks for watching and Stay Tuned!

Thanks bro! Finally someone breaks it down with further visuals & I’m about to finish this today
Not a problem. I’m just glad I could help someone. Hope to make more in-depth videos in the future. These under the car angles are not easy 😂
@@boostdynamictuning how much of a horsepower gain can u expect with test pipes? And are the IAT’s Better overall?
Make sure to note book time on this job call for transmission removal. Nearly 12 hours of work. If you are installing test pipes you can cheat it but every shop will put you at book time of 12 hours.
Been searching so much for this information. Thank you for making this video. Everyone else just glosses over this part.
No problem! Glad my video can shed some light on the job. It's not a fun one, that's for sure!
@boostdynamictuning I got under the car and inspected what was actually wrong. Right side cat separated from the flange where it meets the manifold. I got it out by lowering the transmission and using rachet strap to pull it to the left. Removing the O2 sensor before trying to fully drop the cat down made it very easy to remove. Friend welded it back up. Got it back in the car the next day and she is purring like a kitten again. I have less than $100 in the repair, mainly new gaskets and studs since two of them came out unbolting the flange. Local shop wanted $4k to do new test pipes with G-sport high flow cats welded in.
@@armourbl smart move with the straps. If I had time... which I don't. I would uodste the video showing the watched strap trip. Props to @jhmmotorsports for sharing this trick originally.
52k on the car and with new pads, rotors and custom painted calipers in Red Enamel high temp caliper paint. BDT has improved my cars power so much so. That other cars that beat me in a drag now get gapped by me! Absolute best $$$ spent. Wishing I did it sooner because it makes me love driving and the car much, much more. Go with BDT. You won't be disappointed
Put 5,000 miles on my BDT tuned Jetta Sport 1.8T. Stage 2 is amazing! This car pulls like never before; when it was stock you would accelerate quickly after 4k rpm. Now at 3k it makes boost so fast and hard you have to grip the wheel to hang on!
hey i’m loosening the sub frame and it won’t even budge 3 bolts on each side right ? i need help
This job is an absolute nightmare. With all the extensions you need to reach the nuts, you can't get a good bite on them. Trying your method of putting a stub wrench on the nut and prying with a long pry bar. Hopefully I can get this done soon....
Bought to tackle this, i read here book time is 12hrs but how long did it take you? 4 hrs?... ty
Do I need to support the engine from up top for this? If so what do you recommend to support it?
Is gutting the OEM cat an option, is it easy enough to do?
The sound will be raspy and drone now, did you do any mods to change that or just the OEM system remains? If so how does it sound test pipe to OEM exhaust?thanks for the video.
It this on a manual or auto or does it not matter the trans still needs to be fiddled with?
Is this a DSG or manual Trans? Sorry for the dumb question btw... But mine is a b8 with dsg and i have to replace the left cat due to failure. And dont find any good videos, except this one.
This is for a dsg car :)
Did you have to put the car in service mode to do this?
Thank you!!!!
No problem! Glad we could help :)
Gracias por mostrar un algo ddel proceso.pero me uviera gustado que enseñaras como quitar los sensores de oxigeno 2
How many bolts to lower the engine cradle? I only see 4 per side
I believe you’re right with 4 per side.
Good stuff.
What is the torque spec for the subframe bolts? And how many subframe bolts do you need to loosen on each side?
About 10 ugahduggahs
Torque spec is usually till your impact stops turning it
It’s usually 90-120nm+180°… it’s pretty specific so don’t listen to the bafoons that use their impacts lol
If lowering the engine and subframe together would you consider disconnecting cv axles to not put stress on them
It's not as low as you think. Cv's don't really get stressed out during the lowering of the sub frame. At least not that I recall. I usually look for these kinds of things.
Which test pipes did you buy? I want to just gut my cats but I’m worried I won’t be able to get them past my dsg.
We bought Redstar test pipes. You can get the cats past the DSG, it's just not easy. lol
@@boostdynamictuning Is it any easier with a manual?
@@TH-camHandlesAreStupid I am not too experienced but if you look on the audi forums I believe it is easier with the 6mt
Hey did you get a chance to see how much room is above the "body" of the cat where the o2 bung is? I know some guys run gutted cats. I'm wondering if a spacer can fit in that space where the o2 bung is? Thanks!
I would NEVER recommend installing an o2 spacer. You are faking readings that the ECU is interpreting. Have your tuner adjust the tune accordingly, and you'll be all set. Thanks!
will these test pipes fit ECS downpipes or is it just for the oem downpipes?
Fits oem or ecs
Did you replace the muffler bearings?
😂😂 just replaced last night haha
😭
My redstar downpipes keep breaking, chatted with redstar and said if I have the bracket that holds the cats, I don’t see any bracket. Anyone else having breaking issues?
Not one single customer has reported this.
Only way you're braking those think downpipe is improper instalation.
The bracket isn't installed or you have bad engine mounts. Red starr has the highest quality downpipe on the market. Not one competitor compares. No I'm not sponsored, and I paid fill price for my set. Honest review.
Got a mobile mechanic who thinks he can tackle this. But dropping the gearbox instead as I have a flywheel rattle I'm replacing the dmf too. Think it's actually possible to get the gearbox off on axels?
Wouldn't suggest that, do it the way I did in the video and be done.
Are you sure it's the flywheel? I have a b8.5 with a cracked flange on the drivers side cat, sounds A LOT like what you'd expect a flywheel rattle to sound like. Kinda of metallic ringing that's in sync with engine RPM.
Food for thought before you go pulling the trans!
is it possible to remove the cat without cutting them ?
Yes, but you need to drop the trans and engine support down very far.
having a hard time locating all the subframe bolts :/ i have the trans brace lowered pretty far and the cats cut but still don’t have enough clearance. from what i can see all the subframe bolts are loosened
Try using a strap and ratcheting to the lift to pull the trans. Watch Jim's video on how to do it if you need another opinion on it.
@@boostdynamictuningyou know the torque specs for the trans brace bolts? and where i could find a replacement bolt?
@@ninjastealth2704 check my b9 s5 trans flush video. I think I have the specs there.
@@boostdynamictuningjust checked that out but i’m looking for the trans brace bolts you lowered in this video, i broke one of mine.
Just broke a stud that connects the cat. what is the best way to get it out?
Get a legit torch, heat it up till it's literally glowing red, then get a pair of sturdy vice grips. Grap on to it and hope for the best. If that fails then you might need to grab a stud extractor tool and also heat it up.
What side is bank 2
Drivers side
any advice on how to get the driver side 02 sensor out? Got the cat free just can’t get an angle on the 02 to remove the pipe.
The exhaust needs to be bolted up to remove o2.
@@boostdynamictuning is that how you did it? doesn’t make a lot of sense since it’s on the top side of the cat. seems like a tight space to not get any strength on ir
@@xulogy3947 I do this every time
Watch the video, shows how I did it as well.
@@boostdynamictuning at 2:10? With a 02 socket im assuming
@Xulogy I thought I posted an updated video? I get the o2 from the top 100% no other way
Can we get a tools list?
how long did it take from start to finish would you say?
I would say 3-5 hours if you’ve done it before.
10 hours of it’s your first time. The learning curve is big on this job.
Thanks for the info my dude! Same as SQ5?
Will be going stage2 single pulley.soon like in a few weeks. How long on stage 2 E40 before your catts start to fail?
@@lou4nysq510 Mine are garbage with the same setup after about 5 months
Why they was damaged.. did you have pops and bangs on it?
They weren't damaged? Shoot me a time stamp for the reason you believe they're damaged.
Is this on auto or manual trans
Dsg/auto
How much would you charge to do this?
depends on where you live and where you go could be 1200-2000 USD in just labor because they're going to book you for 12 hours of work
Manual or auto in this video
Dsg
Damn there’s no way to get those out without cutting ?
There is a way
You can hook a strap to the trans and pull it towards each side to try and sneak it out. I just hate trying to sneak things out and I’m never going to use them again.
@@boostdynamictuning The cat unit looked like it was in-tact though. No damage to the catalytic core, so they're still good for cat resale (metal recycling), yes?
do yu need a tune for it ?
You don't
Of course, you'll throw a check engine light, but your car will run perfectly fine.
@@boostdynamictuning can yu put a spacer for the o2 sensor like how cts turbo has in there test pipes
Lmfao bro what the hell did you do with the passanger side
What do you mean?
@@boostdynamictuning I’m legit so stuck and I can’t find anything else to do
The O2 sensor is getting stuck, I can’t remove it cause I can’t put enough strength or have the space to twist the ratchet enough to just pop it loose I already cut half of the pipe..
@Danny PSI hmm, are you trying to remove the o2 while the cat is still bolted to engine right? If you can't sneak out with o2 it's time to drop the trans as far as possible and Rachel strap the straps to the lift arm. Using the rachet strap pull the trans to the opposite side of the exhaust you're removing. See if this gives you enough room
Ok so, I broke a stud. Driver’s side. What now???
Get an actual torch. Heat it up till glowing read!!! A must. Don't you dare touch it unless it's literally glowing RED!
Get a good set of vise grips. TWIST THE STUD OUT with the vise grips. I've done this and it works.
