Removing the rasp on this exhaust?

I don't know. I found another like it on ebay. Love the tone but not the rasp at revs, I assume it only gets worse as RPM's climb.
So hopefully my HF cats will somewhat suppress that.
Assuming this has test pipes... The cats will suppress most of that rasp. OEM Cats will get rid of all. 300 cell HFCs will get rid of it mostly.. 200 cell.. sort of. 100 cell you'll notice some improvement - you get the point.
The bark as [MENTION=4282]docjohn[/MENTION] said will be attenuated as well. The tone will also get noticeably lower tone. Technically, it doesn't get lower tone, the cats just filter out the higher frequencies better than the lows.
I'll post a video of my setup with 300 cell HFCs. I'm calling it my Laguna Seca setup. The cats alone dropped it 5-6 dB on a meter. I'm at about 95 dB now from 20ft away on a WOT pull.

I am almost done. I see a light at the end of the tunnelits great to have members who pay attention to the details of mods.....ryu has been on quite a journey with his car....
(I just bought a OS Giken LSD. There's really nothing left to buy LOL)
Thanks for the advice Regan. I am rather disappointed though. I have both 300 cell cats and res TP's from Pride and really like the unusually nice tone of this exhaust plush 3' should flow great for NA. Seems to be well built as well.

Hi Dave, contrary to popular belief, 3" is way too big for an NA. I'd stick with 2" for each bank. Keep the exhaust velocity high. It'll sound better too.
