help with header choice

[Txjose]

ARH and don't look back.

 

I had the volant /corsa catback and good god that was a loud exhaust. It got really annoying really quick.

 

So i left the 3" tubing and went with a 22" magnaflow... Much better!!

 

Also went with 1 7/8" catless. No loss in low end and glorious top end.

I would recommend the kooks header and y pipe, they were installed on my friends 2014 5.3 and sounded amazing and kooks are amazing quality pipes. I actually have some for sale and if you are interested send me a pm and we can talk. I also have a video of them on my friends truck along with the same exhaust as you on it. Let me know

I put on Catted 1 3/4" ARH headers. Still getting a CEL for catalyst efficiency. I can say this, you need a tune with them. It's night and day difference.

Currently running ARH with cats/Corsa Sport, sounds INSANE wide open throttle, but it also just as insanely loud. Ran no offroad pipes before and had to change to cats due to being to loud for daily driving. I'm happy overall, but did had some problems. The ARH had exhaust leaks due to bad flanges, it would slip no matter what, had to tighten it five times till I got real tired and decided to weld the flange to prevent it from slipping. Also has a raspy sound that is annoying, but nothing will beat the sound when WOT or accelerating.

Do you have cold start video (with cats). Is it super loud with normal driving?

There's no point in getting headers if your not going to tune. It will run lean and the ecu wont learn, there's too much of a difference between the stock manifolds and long tubes, more so if your running an intake and catback.

I run the Corsa Sport with American Racing LT's on my 2010 5.3L and Corsa Touring with Dynatech LT's on my 2009 6.2L.

 

Installing headers will definitely not void your warranty. I've run LT's on my last 3 trucks, my Z06 and my GT500 and the dealerships have NEVER blinked an eye and I've openly discussed it with their guys in the service department. Heck, on my 2009 Silverado, I had to have the torque converter replaced under warranty, and the service tech merely commented that they had to remove the cats and part of the piping to get it out, but that they torqued everything back up otherwise. As well, none of these were professionally installed. I did them all myself in the warehouse at my office. It took a few days, but I never hit a point where I realized that I was in over my head.

 

Where you will void your warranty is if you do a computer tune to maximize the gains, but you can easily run headers without any ECU tuning. You will pop an occasional CEL as the O2 sensor efficiency will be out of the programmed range, but a quick code reader can clear this.

 

Definitely make sure to get some good quality stainless headers. I'm extremely impressed with the finish of the AR headers and would recommend them to anyone.

 

The below video is how the Corsa Sport/LT combination sounds on my 5.3L Regular Cab

 

 

Which dealership?
