EDIT: Wait, am I reading this correctly? You are limited in your options? You might be able to have resonators welded in somewhere...

No it won't. I have double resonated test pipes. They don't do much. Art pipes probably would

Really? I originally had straight pipes, which was unbearably raspy on coast down, and then switched to CNT resonated TP's and that was a 100% improvement.

It still had a little raspiness, so fair enough, but it was substantially reduced as compared to the unresonated TP's. I'm surprised (and disappointed to hear) your double-resonated ones don't knock it out entirely.

Also, is your set up a custom one? I didn't even know there were double resonated TP's.

bingo!!

to kill rasp you need a helmholtz resonator like an ART design. an inline doesnt do crap. or you can add your own. i did mine in the X pipe and hey work 100%

It's amazing the difference the Helmholtz resonator design makes. I have yet to hear a raspy setup matched with ART pipes (including the HKS exhaust).

You heard hks exhaust + art pipes combo with no rasp?

So essentially it's just a resonator but capped off at the end? Any muffler shop should be able to fab this up, right?

I have test pipes waiting to be installed and you're all worrying me with this talk of rasp...
