cats back
No clips-but I can say for sure now---those clips are nice but they don't sound like being there. I heard this beast last night when I let my stepson drive it. Sounds like a monster! It might as well have open headers. Car is healthy, mean and tame when you drive it like the cops are behind you. When you step on it the gates of hell open. I've heard this setup on you tube etc., and those sound bites only give you AN IDEA of how it sounds. It is truly raucous. I'm not removing anything. I just want to quiet it a little and get rid of the fumes.
