how would true duals, no crossovers...2.5inch pipes to flowmaster 40series sound on my 01

 

great. not too loud but still pretty damn loud when under acceleration.

 

wat could i do to make it loud...mustang loud..not annoying loud...i dont care about drone or cops...i just want it to sound like a stang

 

dumps

 

take off the rear cats, that wont be emmisions legal though. thats about all you can do. that or dumps but dumps will be loud and annoying inside the car.

 

i have the exact original setup u are talkin about with cats and love it, i am gettin my cats off as soon as money permitts but do what u want, with em on it still sounds good, and dont dump, it will echo really bad
