HFC and exhaust rasp
Right now I have stock cats and Y-pipe, a coupe mid-pipe with a Moroso spiral race muffler in place of the stock resonator, and no muffler. Just a 2.5 pipe with a tip out the back. It sounds so good. I would like to upgrade the stock cats but I do not want to ruin the exhaust note of the car. Are all CAT upgrades going to produce a rasp in the exhaust note. I want no rasp, not even a little.

Any rasp you'll get w/b at WOT
NJ6MT, consider the fact that most of the restriction in your exhaust system is in those OE cats. Replacing them with quality HFCs like Fast Intentions will easily give you another 10 to 12 WHP. Any rasp you might get will be because of that OE y-pipe, it's like putting 2 lbs of **** in a1 lb can due to the extra flow...get the concept?

I don't know if you wanted me to say this but I hear a raspy exhaust note that I don't want my car to sound like.

So what exactly do you have?
- ART pipes
- ??? Y-pipe
- ??? midpipe
- HKS muffler?
Please keep in mind I do have a Sedan, I don't know what you have.

These did me so good, they are thick and not cheap/tinny like berks. I can't speak for fast intentions though. No experience with them.
