I've got an 03' JCW. The JCW exhaust is quiet...really quiet. Although when you are stopped and rev it up a little, you can hear it pretty good....when you are actually driving in the car, it's really pretty quiet. I've driven a few stock S coopers, and I think my JCW exhaust isn't really much louder than the stock MCS exhausts. Even after I removed the resonator....it's really quiet.

I want something I can hear a little more....not something that's loud and obnoxious...just something that sounds a little more "sporty"....and has some "pop and burble" to it. My exhaust seems a lot quieter than the videos of seem of other MCS's with the JCW exhausts on them.

What would you guys suggest?

 

Stick with the exhaust, add a header.

The JCW exhaust is actually one of the better performing exhausts out there, a header will give you near the same sound under normal use but considerably more under harder acceleration.
