Kooks and OBX make long tubes for the 6.2
Remember a tune will be needed to get the most out of them.

 

Spend the money and get a nice set of Kooks. They'll last the lifetime of the truck unlike some of the cheaper guys out there.

 

Very happy with my Kooks 1-7/8" w/ catted Y-pipe setup. Bolts directly to the factory 3.5" cat-back and sounds fantastic. No drone and not obnoxiously loud.

 

Yeah I think I'm gonna go with a kooks and xpipe. True duel. It ain't cheap though lol

 

Just installed American Racing Headers Long Tube Headers:

So am I gonna need like a custom tune or will a "on the fly" tuner work ok

 

IMO a custom tune, done in person is the only way to go. Cost is about the same as a mail order, cheaper in some cases. Search around locally for a performance or speed shop and they can hook you up.

Yeah only few shops I know locally are Danville Performance and Fleece Performance (I used to have a Duramax so I know all the diesel shops around), but I think Danville does a little bit of everything.

 

I ended up taking a video the other day of my exhaust setup at start up and idle, before I do my cam swap.

 

Kooks supporter here. Ordered a set with ceramic coating, and kooks y-pipe.

Sounds great, wish you would have stepped on it a couple times to hear it growl.

 

Stainless Works is what I have and they are a new vendor here
