im thinking of putting a different muffler into my tsp rumbler,it sounds good but it sounds like a truck, should I go with a chambered muffler like in the gmmg or a flowmaster 1 chamber?? I want a more camaro sounding deep tone instead of the just plain loudness I have now

 

most chambered mufflers i've seen restrict down 1/2" below the "inlet/outlet" diameter. which could increase the restriction.

i would say go with something like the borla XR1 or the magnaflow 4x9" straight through muffler.

i know the magnaflows sound awesome on my true duals (cammed LS1 w/ LTs)

 

My TSP Rumbler doesnt sound like a truck on my LT1. I actually get compliments on it all the time.

 

Magnaflow...
