Fast Intentions High Flow Cats

Makes sense. I've had hfc on my previous car and was curious, for your car regarding having the oem cats, test pipe and hfc. Is the testpipe considerably louder than the hfc. Im running oem cats with FI cat back and I wouldn't mind a tad bit more roar

Yeah the test pipes are definitely louder than the hfcs. The hfcs are a lot louder than the oem cats and the test pipes are a little bit louder than that plus a little less bassy. I have resonators on my test pipes and catback setup because I'm not super into the higher end sounds. I almost wish I went with the 18" resonator and not the 12" for the catback for the deeper sound, but i don't think it would have been a big difference. the hfcs I'm selling are non resonated btw.
