Which exhaust should I get?

FI OPTIONS:
high flow cats w/ resonators - least power gain & least volume/drone
HFC/no res - low drone decent power
test pipes w/ res - good power slight drone reduction
non-res test pipes - most power/most noise
long tube headers -

CBE:
18" resonators - least drone, slightly less ext volume
12" resonators - small drone
no resonators -

on a sidenote pretty much any aftermarket exhaust there is going to be some drone at some RPM its kinda how sound waves work and if you want to add some power/volume you cant be a little bitch about a bit of in cabin noise. its a sports car, its how it should sound.

i have the non-res CBE w/ CF mufflers and non-res TPs. also i have my set of FI straight pipes.

Yes, they are Tony approved! Frank, when I get around to it, I may put your pipes into production. We will call them, "The FP" option.
