is dual three inch from headers back too big for a cammed 5.3?

 

anyone?

the truck has a tr220 cam if that matters.

 

I would think you would be okay... most people i know do 2.5 duals with an unmodified engine.... my guess is it would help flow better

 

thanks i really appreciate it.

 

No prob

 

You will lose some low end tq with exhaust that big.

 

Dual 2.5 would be better.

 

Yea thats a big exhaust for that engine. Not ideal. A single 3" would probably net you more power under the curve, and definitely help down low. Thats what I would run with a cut out that you can open after you get out of the hole.
