KMS Firestorm Exhaust System - Volvo C30 Pre-Facelift

Loving it!

It's a great system, fits perfectly and easily as long as you can lift the car with a proper lift instead of a floor jack like I did. Resonated sound is civilized enough not to bother the neighbors when you leave in the morning but growls higher and louder under higher load and rpm. It's not a screamer by any means but more of a quiet performer. It doesn't drone per se with regular driving but on my car at least I do have a louder low rumble inside the cabin then it does out the back but that's probably due to my install than anything to do with the exhaust itself. To note though my current setup is 3" stainless from the turbo but made myself a downpipe with the original CAT while I wait on more upgrades before a more suitable high flow cat and tune. I recommend!
