I currently have the FI CF cat back with no resonator in the mid pipe, and on cold start up I experience a little bit of rasp that goes away.

Will RHFC add rasp to my exhaust system?
I currently have the FI CF cat back with no resonator in the mid pipe, and on cold start up I experience a little bit of rasp that goes away. If I add the FI RHFC will this rasp be increased and will I hear it all the time instead of just on cold start.

Yes you will. I would look for resonated cats if I were you. It will reduce or eliminate any rasp and keep a clean exhaust note. It will cost more, but it's better to get now than to spend more money later.

from what i understand,any hfc or test pipe will add rasp to our cars. no matter what. im also considering buying the FI resonated hfc,for power gains and to add a bit more sound to the exhaust...however i dont want it to sond like a bunch of rasp.
but resonated would be the way to go to help avoid the rasp. |

that being said there was a forum member who has test pipes with a catback and got rasp, he modded his exhaust with helmholtz resonators and now gets a clean exhaust note.

Resonated high flow cats will not cause rasp. I've ran them in the past (Fast Intentions) and loved them.

yes deleting your stock cats whether its test pipes, high flow cats, art pipes (resonated test pipes) or resonated high flow cats, will bump the exhaust volume
resonators help a lot with rasp, inline mufflers help even more
