Planning on having custom 4" exhaust from the turbo down and dump it before the axle. Looking for a good high flowing muffler that will take some of the sound away because i dont plan on running CATs but have it still be fairly loud. Was looking at the XR-1 muffler but started to think that might be to loud. Anyone have any suggestions?

 

Magnaflow and Dynatech also make 4" mufflers

 

XR-1's are one of the more tamer mufflers

 

in terms of sound dissipation? cause its going to be driven on the street cant be insanly loud but loud enough to get some attention
