What is the best exhuast to get since you cant do true duals or is there any way to get around voiding the waranty but still having true duals?

 

about the only exhaust changes you can do without voiding the warranty is just changing the muffler... and even with sometimes that s sketchy.... this is just my personal experiences.

 

I thought the Corsa exhast was a good option..... is it not?

Thats what I was planning on using

 

Yeah but Im not sure if it voids the waranty

 

Corsa will not void your warranty nor will any aftermarket muffler.
A dealer has to prove the part that you added caused the failure in question if there is one. They cant just say, "oh you have a muffler, we're voiding your warranty" Oh, and Corsa is an officially licensed GM product.

 

Thats exactly what I was thinking.....

Of course everytime I think...Im usually wrong

 

I was told by my service manager that it will void everything after the cut/weld. So if you add a cat back it will just void your muffler and tailpipe, which is off anyways so it is no big deal...

Actually I made my exhaust into duals with a dual in/dual out muffler and I have brought it into the dealerships several times and they said nothing. BTW duals were a huge mistake IMO...

 

Again, nothing can legally void your warranty unless they can "prove" it caused the problem. There was a specific court case that defines that. So you can throw on a supercharger,full bolt ons,cam, and the proceed to blow your transmission to hell and they'll have to prove the added power caused the tranny to fail.

 

if it helps any, here is a Corsa Sport on my '07 Avalanche:

 

I was looking for a sound clip.....THANKS!
Have any more?

Does anyone know how much difference there is between the touring and the sport?
