looking for a cat-back system?

[cycleman]

want some type of exhaust that has a good deep sound.

A cheap and effective way is to replace the existing midpipe with
either a crush bent or mandrel bent pipe. Sound is deeper and
not harsh enough to sound annoying at highway speed.
Perform a search, you should find lots of people here that have
done this with sounds, including myself. hth

Thermal R&D Stealth Cat-Back.

I LOVE mine!!!

Very deep sound. None of that raspy lawn mower shit either....
