I will be buying the Dynatech long tube headers w/ cats.
Basically, which cat back system will work and sound best with this set-up?
I've looked at magnaflow, but I'm skeptical because it is too quiet. It sounds good for the 5.3 trucks, but the LQ9 6.0 exhaust system has dual exhaust pipes going into the muffler instead of one.
Any suggestions?

the magnaflow aft cat setup is not quiet by far.sounds damn good cruising and when you get on it ..it roars...

 

I WOULD GET MAGNAFLOW ANY DAY THAT IS MY NEXT PROJECT

 

with the headers on there, quiet won't be a concern.

 

I just want to make sure it's not going to have an abnoctious raspy sound to it like others complain of with long tube headers.
Does anyone have a sound clip of a LQ9 6.0 engine with long tubes w/ high-flow cats and a magnaflow cat back system?
Any VHO, SS, or LQ9 6.0 swap owners????

I think Magnaflow sounds great on about anything, sounds nice just cruising and then really talks to ya at wide open throttle. My buddy and I do some auto detailing and we had a dodge dakota the other day with the small V8 in it, had magnaflow cat back system on it and even it sounded mean as hell and I am no dodge fan.

 

I got my exhaust done yesterday. SW LT's, high flow cats, X pipe and dual 18" magnaflows. I live in Ft. Worth I will PM you and send you my number call and I will take the HO down the road and let you hear it.

 

if u had no cats it'd be raspy, but since ur using cats it won't be as raspy, if at all.

 

Corsa or Magnaflow you will be happy with either one.
