FI Exhaust 12" Resonators to Non Resonated

christian370z

Recently, I have been thinking about changing up my exhaust a little bit. I currently run an F.I. cat-back with 12" resonators and Berk HFCs and have been looking for a bit more volume as of late.

Has anyone made the jump from resonated to non resonated FI exhausts? How much additional volume should I expect? Any increase in rasp? Thanks in advance!

I did this... it will add a lot of rasp to the mix. It increases the tone of the exhaust, it will be a good bit louder as well.

I'm guessing you're looking to go non-resonated because you can't do headers or test pipes right?

Sorry for not responding sooner, been really busy lately! Yeah, I can't really go with LTHs just to avoid headaches come emissions time and I don't want to have the drawbacks of test pipes (loss of torque, rasp, smell)... Ah, so it does add some rasp then. Darn, I really don't want to add any rasp.
