So currently i have a full fast intentions SS CB Exhaust with 12" resonators. I am looking for more sound but have no idea what to go with. What are your thoughts on the RHFC? Is my exhaust going to be any louder with them or is it just straight performance.?

 

FI RHFC is awesome. I loved mine. Had to swap to RTP due to nitrous install. Selling mine now in the classifieds here if your interested. You cannot beat them for sound, quality and gains. TP's you may get a little more power up top but you will lose some low end. I know from experience.

 

They both perform identical from a hp standpoint. The non resonated will increase your sound more than the resonated. I just installed the resonated version and it did add some decibels to my stock IPL exhaust without question.

 

High flow cats and test pipes will perform very close to each other but sound very different. RHFC are your best bet overall with exhaust note, emissions and rasp all in mind. RTP are quite a bit louder and may get some rasp depending on your cat back setup. I love my RTP but here and there I wish they were just a bit quieter. No regrets though and they're never coming off, because racecar.

 

The HFC's will give you better performance along with a better exhaust note. As stated above, they are not as loud as RTP's, but they will give a less raspy exhaust.

Are you currently F/I or N/A? What are your long term plans for the car?

 

Incorrect. High flow cats WILL NOT out perform test pipes but do sound better.

 

High Flow Cats will give better performance than stock catalytic converters. I was not saying that they will out perform test pipes, sorry, I should have worded my response better.
