Just to let you guys know my exhasut setup is: DC headers/Crawfords/JIC Ypipe/Amuse R1 Titan

As it is, I believe the Crawfords are already relatively restrictive compared to the rest of the metallic HFC's...so to get anything less restrictive will probably produce more rasp, if anything...the only thing that is probably more restrictive than the Crawfords are the stock cats and the Nismo HFC's (which I am not willing to pay $2k for anyway)...

It's kinda sad that I waste the lovely sound of the Amuse when I boost and it rasps, but I guess I wouldn't trade it for the 20 hp I gained with the Crawfords and freeing up more hp with less boost (safer on the engine)...probably should be happy with that....

The Nismo cat's have been discontinued for a couple of years now.

If you want baller JDM cat's get Mine's or Power Enterprise HFC's. I run the PE mettalic HFC's with HKS GT SC, Nismo Headers, Tanabe Y-pipe, and Amuse R1 Titan exhaust. Before the SC, I noticed a little rasp b/w 3-4k rpm. Now, I can't hear any rasp.
