I have a suburban 1500 2006, 6.0L... looking for a cat back system that flows good but does not resonate at certain RPMs. I have even thought about running two stock setups in parallel since I have had such bad experience with exhausts in the past. I just want a system that is not overly loud and does not resonate.


Any recommencation from anyone?

Thanks

 

I would say my first choice is Corsa its expensive though second choice would be Magnaflow Ive had good luck with both.

 

my gibson setup is pretty mild. not sure how it would be on the 6.0 though.

 

I have the hooker aero with no cats and i love it. It has no resonation and is quiet at pert throttle but very nice at wot. Whatever you do dont go with the flowmaster. Your ears will bleed on the interstate!

 

I had heard the Corsa resonates a lot? Not true? around 1500-2000 they all seem to resonate at some range (from what I was told). In my last suburban, I could not get anyone to sit in the 3rd row... It had a Borla

 

my dad just poked some holes in his stock muffler and that sounds fine on his 6l truck

I was getting resonation on my 04 truck cause I had it dumped before the rear axle.. i moved it behind the rear and its to damn quiet now:-P thats with a dynomax round muffler and no cats

 

We,, just spoke with the shop that is building it for me. The ysaid, no matter what which Exhaust I pick, it will have resonance :-(

Man, why can't they design a system that does not. Teh germans seem to be able to do this on their sport cars. Every freaking car I have had that I put on an after market exhaust resonated like hell....

I guess the question is now, which one resonates the least?

 

bet they havent dealt with corsa. it was totally resination free on my truck. ask some of the 6.0 ss silverado people if the corsa resinates on their trucks.

 

Thanks, where can I find them :-)

 

bismarck, off topic but is that an option for 2006? 1500 with 6.0 i've never seen that before, thats pretty sweet!
