I've had the Apexi WS exhaust for several years now. It's very quiet when tooling around town so you won't draw unwanted attention. On the highways it won't drone you out either. The Apexi WS has a nice low note and if you do step on the gas, it will growl in response. Have had no problems with build quality even through a few Michigan winters. I'd recomend this cat-back to anybody without reserve

Great product, if your looking for something that doesnt give you those ricey sound effects and wont make you sound like a bumble bee on crack, this is deffinatly the way to go. When i put this on my car i could feel a serious difference in the lower and mid range rpm range. In my book this product would come highly recommended, no doubt about it.

I enjoyed this exhaust while I had it. It was really quiet around town and never drew any unwanted attention. I went the extra mile and painted the canister flat black to give it a more stealthy appearance. I was very impressed with the finish as it held up over 3 northeast winters. I have since sold the muffler and kept the piping. I would recommend this exhaust to anyone that wants a nice mellow sound that's bearable for all types of driving.

Nice low tone, not flashy at all, gets the job done with power gains. Awesome !
