I have Mac headers on my LT1 and I am wondering what Catback will sound the best with them. Currently I have LM but it is not hooked up to the headers. I am worried the LM will sound like *** becuase I have no cat. Or should I go true duals??

 

the hooker aero chamber, i've heard sounds especially amazing with shorty headers.

I am currently running the headers, offroad pipe, and a flowmaster catback, and it sounds really awesome from the outisde. But inside the car, all that bass and rumble just resonate and make it hard to hear things...

I have a hooker aero chamber muffler in my car ready to go in can't wait.

 

I currently have ATR catback and I love it. I personally do not like the Loudmouth.

 

Check sig. I love the way the Aero sounds. I kept the cat when I swapped in the MACs and it actually got quieter all-around compared to the manifolds, but has a deeper tone. When the summer rolls around I'm making an ORP and putting that in. Then when school starts, the cat will go back in. Can't wait to hear how it sounds through the ORP.

I still think the Corsa sounds the best out of all mufflers though.
