I have the same exhaust and let me tell you that you wont be disappointed with it. It sounds amazing when going WOT, and if you drive at the right RPM you cannot hear it at all so if your cruising with some older people like i do they dont complain at all

 

i think i want to go with the fi

 

I thought that the Stillen basically sounded like the stock but was a bit louder?

 

they arent made, i believe sebring tuning makes them and FI buys them. all of their kits are made on a Jig by hand, so its just a matter of changing the tips at the end.
