O.k, i'm looking into my next mod, thinking at getting the RRM Cat back exhaust with the RRM high flow cat,My questain is now that the RRM cat back has been out for a bit, for those of you who have it, what are your thoughts on it, any input would be great, At the moment my exhaust is stock, would the RRM catback with highflow cat make my car sound rasppy???

 

I did the RRM Catback and RRM High Flow Cat at the same time. You notice the hp difference off the bat. And it wasn't raspy at all. I actually drove my car with the catback on to a muffler shop so they could put the High Flow in, sounded the same deep tone.
