flashburn · 01-27-2014, 08:55 AM

I got the following setup a couple of weeks ago:
RevWorks UEL Headers
Nameless Downpipe - with Cat and Helmholtz resonator
Nameless Axelback Exhaust 2.5" 5" mufflers

Unfortunately it's just a raspy mess. It's slightly noticeable below 4K RPM, but at 4.5K and up, it's constant, just sounds horrible.

Not sure if anyone else has this setup or not, but I figured I'd give people a heads up that were thinking about this same setup.

Any suggestions on what I can do (if anything) to fix the rasp would be appreciated.
