So, I'm better off cutting my muffler off and putting in a straight pipe....saving lots of money?

 

Or you could cut out your muffler and replace it with a nice Magnaflow, Hooker Aerochamber, Spintech, SLP...whatever

 

I want to run an Aerochamber, spintech, or borla XR-1 sometime in the future.

 

im telling you dont get gibson,there stainless sucks mine is amonth old and already is rusting and i called them and they said that rusting is not covered under warranty and i paid $800 for there cat-back it sucks i hate gibson

 

Back to the Op, Corsa is the only one I have found that makes a complete cat-back system for the NBS crew cab V-max. And it is actually listed for Sierra Denali crew cabs. Very pricey, But I have never heard even one complaint from a Corsa owner about the actual product.

I've had Magnaflow and Gibson systems on previous trucks. I'll never buy another Gibson, and I might just replace the stock muffler on my Crew Cab Vmax with a pseudo - stock replacement Mganaflow, just because of the price of the Corsa.

 

Also anything listed for a Silverado SS will work. All 6.0 half tons that I know of share the same dual in/dual out set up with the y-pipe after the muffler.

Gmpartsdirect has a GMPP branded system listed for 419.00 that is all stainless. I believe it's made by Borla for GM. GM PART # 17800765

I modded my stock muffler, the pipes GM put on the VMax are pretty stout.

 

I have the Corsa Sport. It's the greatest cat-back that I have ever encountered, period. It's so darn easy to install, a 2 year old could manage the task of putting it on.

 

I'd have a custom catback built for me before I ever paid $750 for a catback.

 

Do you know for a fact that a cat-back system for a SS which is extended cab will fit a crew cab truck?

 

I thaught that was the case, i just went looking for something to back up my statement, and can't find anything....

The one post on another forum I was thinking of is a guy using a SSS catback on his extended cab VMAX, not on a crew.

Sorry to get you hopes up, I will update if I find anything.
