From the best I am aware, GMPP exhaust is being made by Borla. Either way, you aren't going to find a true dual cat back system in a kit for your truck. Unless you're making alot of power, the single is going to be just fine. No need to carry extra weight around.

When I ordered my Borla, I talked to Borla and they said they didn't make them for GMPP. I am almost positive it is corsa from what I have heard. You are correct though, there is no true dual kit out there... There is only the single in/ dual out kits... GMPP dual out kit won't work without removing the spare... I am pretty sure Corsa would be the same.. That is why I went with Borla.

Like zippy said, the Corsa's are made to fit the vehicles without having to remove anything. If you have a muffler shop that's worth a **** they can make anything work. For instance, my Corsa Sport came off of a '04 crew cab 4x4 truck, then went on my '05 crew cab 2wd truck, and is now on my '07 Avalanche. I took the dual exit clamp off and made it a single exit with one Corsa tip instead of 2. Anything can be made to work.

I have had Corsa on other vehicles, and they have all fit very well. I just can't figure out why GMPP makes an exhaust that Corsa manufactures that does not fit without removing the spare?

Are ya'll talking about a remote start that came installed on the truck or an aftermarket one? My remote start works fine.

Default How Bout Headers

What size is the corsa? 2.5 or 3.

I want 3 inch single all throughout, however, I've called for Pacesetter LT's and was told they wont work for my truck. I'll have to put new cats on and "void the warranty," I just want to make it work. So if I buy LT's for a 2006 5.3, since thats all I can find, will they fit on my 07 5.3 NBS, and will I be able to match them up to some 3'' high flow cats.

From all that I have heard, the GMPP Cat Back uses a Borla Muffler.
