The resonator came with your hf cat? I didn't know hf cats can come like that. Does the RP come this way if this is true?

 

The RP high flo cat does not come with a resonator on it, however, you can have one added on. Just talk to Chris at RP. They've done it before.

 

k, im gonna sound like a douche asking this.. but what does RP stand for? ive tried to search but its "to short" and ilooked at the top of the main page where it has all those groups and what not.. couldnt find one that had Rp... does RP stand for.. Racing pipe perhaps?

ah, kudos, thanks <<no homo

 

Which will make it less noisy, but also less flowing?

 

^^^ Correct. You can always try it out with just the cat first (as that in itself will reduce the noise vs a straight midpipe) and if it's too loud, you can get a local shop (if you're not in the DFW area) to add one on it later.

 

Sorry for the random question, but would adding the RP Supercat affect the Mazda warranty?

 

I don't get it. How a straight through 3" resonator can affect the flow?
