We have the same mufflers, Flowmaster 40's
Mine has a catted x, yours is a stock H with 4 of 6 cats removed..
You know what mine sounds like, a catted H would rumble like yours, but maybe a little quieter
You also know what an O/R x sounds like on your car too.. lol
well technically, it only has 2 removed, since it was from a 01+ lol
and i like the sound of the h, its all beefy and i'm not so sure about being quieter...
and as for that or pipe, it sucked, a lot... i got less hp from it, but then again, it was a Pypes O/R, i wonder if its different from a different brand
