ABSOLUTELY AMAZING

Exceptional

I had considered doing a full tbe, but decided to just try these to begin with. Excellent craftsmanship and sound. Very glad I went with stm, over invidia, nameless, etc.

better late than never

Ive had these on for a month or so, and just thought to do a review. Looks are amazing as you can tell, but the sound will put constant smiles on your face. Lets face it the stock exhaust is not ultra quiet but waaaay to tame. These give a much more aggressive sound but still not obnoxiously loud. Stay fairly low rpms next to cops and no problem, Open it up under a overpass and your ears will thank you. One of my favorite upgrades I've done so far. Install was no problem in a driveway. A+

CRAZY

Best exhaust I’ve ever had... you can tell they take their time with the welding and the noise is amazing. Couldn’t be happier and will be back to buy more parts ! Thanks again STM team.

Best axle back for the money

Great product. Welds look amazing compared to everyone else's and the burnt tips looks so much better than any other axle back exhaust

Thanks for the awesome feedback, Brandon! We're glad you noticed the detail of the welds and construction of the exhaust. We put a lot of design time into this axle-back exhaust, and we're extremely happy with the result. Enjoy : )
