My buddy has a 06 cateye, he’s got speed engineering long tubes, going into 3 inch true duals with high flow cats, bullet mufflers, and an x pipe. In my opinion it sounds awesome! It has a quiet idle, but when you step on it or rev it, it gets really rowdy, pretty poppy, but not raspy at all, sounds really great at full throttle too!
With your post cat o2s you can just unplug those but your main o2s are necessary for the health of the motor and getting a wideband o2 will make tuning alot easier
I bolted shorties on my 4.8 because, well, 4.8. No performance boost but sounds great. Easy Peasy, 3 hrs. Worst part was the manifold/ cat bolts. One manifold bolt broken, used an extractor socket, and chased threads on the other sid. I really enjoy seeing you have fun with your babies. Sound mean!
These Speed Engineering plug wires are specifically designed to not burn on the headers. I’ve had Speed Engineering longtubes and plug wires on my LS C10 for a while now and they are perfect
Can you tell me if the O2 sensors would have something to do with making your truck run bad because my truck had 4 of them but I only put two one in each header
Same I don’t like the clap I have the same set up I’m thinking of getting another muffler .. i only found one sensor location for the sensor 2 is that normal
very good install man. I got lucky with my old 04, only 1 broken stud, and I had a stud retraction socket I put on it and spun it right out. gonna assume you welded nuts to the broken studs or did the EZ out and drill method. it took maybe 4hrs to get it all together, went pleasantly amooth. I'd love to put these on my 05 SS truck with a Corsa exhaust system. That frame on this GMC looks impeccably clean, what a great looking truck.
Haha the old broken header bokts..boots... I have done about a dozen header and custom exhaust swaps on these trucks... I always get them out while the heads are hot. Also if you bust the steering bolt loose you have way more room dropping the driver side in. I ended up buying a builder's kit and making my own cat back. Also welded all the joi ts and put on v bands... the entire exhaust comes out only removing 4 v bands and nothing else. Good stuff man welcome to the club. The performance mods will never end now I warn you! Also some are chromosomes header bolts 12 point head will be worth the 35 dollar price.. other bolts rust and break. As far as the smell I put a 3" kooks 300 cell high flow cat where the y pipe merges and a 14" magnaflow Muffler and it sounds perfect with no smell. Also a solid custom tune would be good. Canned tunes are not worth the money. FYI the port in the back is for a wideband...
I can’t wait til you get a cam for chomper! Honestly if it was me I probably would have put the headers on while/ after the cam so you could have got it tuned for everything all at once.
You should put a Moroso Spiral Flow race muffler on it, it will quiet it down just a little bit and give it a nice deep smooth tone. I had one and a 2011 Silverado with a 5.3, it did still have cats but it sounded Amazing. Anyways I love the videos man, keep up the Awesome work👍🏻💯
I just bought the same year color z71 ext cab truck! Bout to slap some headies and exhaust on her thought it would be hard to get some on 4wd but this is what i wanted to see
Just zip tie the back o2s up out of the way until you tune. Might avoid cel that way. Truck just needs to see a difference between uppers and lowers to verify “cats are working “
@@ryanleach3936 it can. Only thing the rear o2 does is measure efficiency. Just needs to see that the air behind the cat is cleaner. Seen it work. Have seen it also not work
Make sure you get the front camber fixed. My truck was like that after i bought it and it chewed thru the sidewalls of my first set of open country tires before i fixed it
Always do exhaust manifold bolts when the engine is hot. Dorman makes a bracket that bolts to the head and holds the manifold down. Been running one for ever on the truck.
Cut the y pipe at the merge leaving you with two 3 in pipes and have the true duals connect there and continue, and throw two small mufflers on, one for each pipe, i have the same headers with an X pipe true duals and a flowmaster super 10, if u want to hear that
i’m interested in hearing it. my exhaust right now is true duals all the way back but i’m wanting to put long tubes on. do you think long tubes with true duals and no x or H pipe would be too loud?
@@liamgeeslin4638 oh long tubes with an x pipe and true duals is definitely pretty loud i ran mine that way before i put a dual in and out flowmaster super 10
Long tubes into that 3” allllllllllllllllllllll the way back! Or have a shop take out that “y” pipe and run the headers some high flow cats and true dual??!!! That would be my favorite and would make Chomper live up to his plate! 😈
I have a 06 Silverado max it's 3 inch duals stock cat to an x pipe and 4 inch tips. Not stupid at idle or even highway inless ya gas it hard it really wakes up so it's good to daily
Need copper anti seize and to wipe the headers off with a rag and some alcohol. If you don’t bolts will just seize again and the oils from your fingers will burn in to the pipes anywhere you touched them.
I’ve got an 05 Silverado with a full 3 inch system with the same headers and mines cammed with some other goodies if you want an idea of what it may sound like? I personally am not running mufflers and it sounds nasty 😂 I like it but everyone has their own opinion but the 3 inch system definitely sounds and performs amazing! Been following your builds for a long time now and I love what you’ve done with chomper 😎
A friend has a 69 GTO with headers , no mufflers only drives it in the summer, sounds good , good enough to draw ' attention ' , the boys in blue liked it so much they had to tow it in for a closer look , and cite him a ticket for no mufflers ☹️
I have this same exhaust but mine leaks from the ears on the passenger side and from most of the clamps which idk why since they are fully tighten and idk why it’s doing that
Get a magnaflow 3 inch single inlet to 2.5 inch dual outlet. The y is built in and used to muffle the sound and its a "through" style muffler so no restrictions and keeps you from having to deal with another y pipe
What are you going to do with the rear O2 sensors I got the same headers but am kinda lost why they only put 1 O2 bung past the headers? I don't think you would even be good for a wide band cuz it's only going to see Bank One

Did the oem y pipe fit, or what did you use for a y pipe with shorties?
@@Pitman556 oem cats to from manifolds muffler. Installed BMRP muffler with double exhaust out back and it looks and sounds old school sick.
Chomper is sounding nasty now! Can’t wait to hear it with a full exhaust!
Thanks your 2 videos helped alot on my long tube header installation !!!
Put DEI heat wraps on the plug wires to prevent burning or heat degradation of the boots and wires. Plus they look great.
These Speed Engineering plug wires are specifically designed to not burn on the headers. I’ve had Speed Engineering longtubes and plug wires on my LS C10 for a while now and they are perfect
Ceramic boots
I run the speed engineering 1 7/8” long tube headers and catless Y pipe on my 2016 6.2L 8 speed Sierra and absolutely love them
Just curious do you have OBDII emmsions testing ?
@@bigstunner1381 No sir

its so crazy looking underneath that truck. im from ohio and my 2014 is rusting like hell

I got all of my manifold bolts out while the engine was cold except for the very back bolts on each side they were already broke lol
yessir been watching you for a while now and i am so glad to see you finally digging into some motor work, keep up the great work bro
Welder is your best friend. I had to extract like 5 of them on my 4.8 I used to have
Just bought these headers. can’t wait

I was literally wanting to run those same headers and a carven on my 03 Silverado, I’d love to hear what that sounds like. Keep up the good vids man!
Those stock wheels look so much better then that other set you had one by far👌🏼

Good Job chase! Interested in how you fixed the broken bolt issues.

Always do exhaust manifold bolts when the engine is hot. Dorman makes a bracket that bolts to the head and holds the manifold down. Been running one for ever on the truck.
I recommend spark plug heat socks to protect them from the heat that the headers are going to put out.
Vv cool. I can’t wait to a get a clean single cab
does this bolt on to the rest of the stock catback exhaust via the same type of flange or is welding required
Cut the y pipe at the merge leaving you with two 3 in pipes and have the true duals connect there and continue, and throw two small mufflers on, one for each pipe, i have the same headers with an X pipe true duals and a flowmaster super 10, if u want to hear that

Dayummm that's a nice truck
I’d love to see you do this with Larry, I have a truck similar to it and want to put long tubes on mine.
I have the exact truck but reg cab shortbox I put tow mirrors on it and it looks really good
Do true duals all the way back I had it on my cateye with long tubes sounds good as hell
She's good bro
These are denali rims but what size tires? I love the fit and even look on your truck. Very classy
I could feel the anxiety while popping those bolts loose . I’m doing the same thing soon 😐
Take a nut and weld it on the broken stud through the center of the nut and remove it just as it cools the weld will not stick to the aluminum head
I have the speed engineering headers on my 2011 silverado with a full 3" exhaust I put a borla xr1 muffler it sounds amazing.
Been waiting for this one yessir
No muffler, take the y-pipe off and keep the true duals
Now all ya need is a set of Black Widow NeighborHaters or WidowMakers and she’ll sound absolutely vicious
Long tubes into that 3” allllllllllllllllllllll the way back! Or have a shop take out that “y” pipe and run the headers some high flow cats and true dual??!!! That would be my favorite and would make Chomper live up to his plate! 😈
What spark plug wires did you throw in there

get some spark plug wire insulators! save those wires from the heat and they are cheap.👍
What brand of spark plug wires did you use? Wanna try msd but liked the way the ones you used fit
Any update
That was good lookin truck when it was stock
Could you have possibly used the exhaust sleeves for that section where it touches the trans cooler lines
Yeeyee, CHASE now its tyme to Cat delete, Long live CHOMPER.Long live GM.Lejune N.C.🇺🇸.
Damn nice interior!!
You should've clean the surfaces and put a little copper exhaust gasket maker and should've put never-seize on the bolts.
on a bmw, the exhaust manifold bolts are called the 24 bolts of death. For anyone that has to do this, I'd let them soak in penetrating oil OVERNIGHT.
Been wanting to do this to my 2011 Sierra
Hey man great video ! Quick question , did the kit have all the ports for the o2 sensors ?
What have you done to your dash cluster? Looks so much better than the stock one
Cam and flow master super 10
Yeeee bud, I gotta donthat to my truck now.
Need copper anti seize and to wipe the headers off with a rag and some alcohol. If you don’t bolts will just seize again and the oils from your fingers will burn in to the pipes anywhere you touched them.
And does the headers and y pipe bolt up to factory exhaust or modifications needed?
Love the videos and chomper sounds mean
You should put a Flowmaster super 10 on chomper
BTR Truck Norris, I’m telling you! Can use a stock converter, and sounds mean!
Runs great too!
What kind of o2 sensors did you run and did you tune it yourself?
Love ur truck content
Just curious did it not throw a code for the check engine light, since you added headers?
Headers don’t change anything because there are still o2 sensor holes in these headers.
@@socal_c10 thank you!
Single inlet to dual outlet muffler. I had magna flow on 03 Silverado. Mello sound low rpm, but wot it was a beast
Sorry no social media except TH-cam
Can select some one else. It's cool
Do I need the longer spark plug wires or can I use the oem ones? I have a 2005 chevy 5.3
I’ve got an 05 Silverado with a full 3 inch system with the same headers and mines cammed with some other goodies if you want an idea of what it may sound like?

You notice any power loss down low with the 3 inch?
Stage 4 BTR cam set. True dual flowmaster outlaws.....
I have this same exhaust but mine leaks from the ears on the passenger side and from most of the clamps which idk why since they are fully tighten and idk why it’s doing that
Did you have to cut anything off the transmission cross member to make them fit? Debating doing this on my 00’ 2500
Need chrome mirror covers but truck sounds roudy👍
Would it be easier to just lower the cross member to get the y pipe in?
5:32 alright pull the motor out. I’m jk just pulling the heads off will do.
In doing the same thing. Question, how did you deal with the o2 sensor for after the cat
Are they still working good for you? Hows the line on pass side?
Keep up the good work 👍.
What's was the clearance between your driver side header and your lower steering shaft? Any bumpage?
Just take the y pipe out and run 3” all the way out to your tips.
What size tip you running.? I got long tubes just ain’t put them on yet
Cam Would Sound Awesome
Where did you get the y pipe from?
Can you put the o2 sensors back in just so the monitors can run for inspection?
Hey man how did you install o2 sensor for check engine ?
Keep it true dual it be interesting how it would sound hopefully not clapping 🤣 but most likely will
2.5 duals are plenty for a 5.3. Would just connect the long tubes to the duals, no Y.
Get a magnaflow 3 inch single inlet to 2.5 inch dual outlet. The y is built in and used to muffle the sound and its a "through" style muffler so no restrictions and keeps you from having to deal with another y pipe
you should take the y pipe out and keep the true dual with cherry bomb glass packs and bigger tips
Bullet race mufflers are great
Might wanna get some Kevlar heat wrap for them
Keep true duals and get a muffler of choice. Black widow is good or carven.
Thanks for this video bro
can i get the link to the headers and plug wires???? it looks and sounds absolutely amazing and i would like to copy this on my tahoe
What are you going to do with the rear O2 sensors I got the same headers but am kinda lost why they only put 1 O2 bung past the headers? I don't think you would even be good for a wide band cuz it's only going to see Bank One
