Great exhaust!

There are so many companies out there now making evo x exhaust systems. I was overwhelmed at first. I was on a mission to find a single exit system that was built well and sounded great. This exhaust does just that and more.

Amazing sound and perfect fitment!

STM's single-exit exhaust is a great way to lose a ton of weight from the stock cat-back. The exhaust is beautiful; I honestly can't imagine that there is a higher quality piece on the market. I paired this with STM's resonated race pipe and STM's open-dump downpipe. The sound is really aggressive (especially at WOT), but not too loud and doesn't drone at all. The fitment was absolutely perfect. Overall, I'm extremely pleased with this exhaust!

We take a lot of pride in the design, fabrication, and development of our parts, so we thank you for the outstanding feedback.Thank you for trusting STM with your build, and thank you for your continued support- we appreciate your business, Austin!

If you want quality look no further. The exhaust looks amazing in person. Fitment is on point and it's lighter than the other SS cat-backs.

Enjoy, Alejandro! We appreciate your feedback, and we are more than happy that you noticed the craftsmanship that went into the construction of this piece. Our guys put in top quality work on every single piece, not just the parts we photograph, so this goes to show that the quality you see is exactly what you'll get.
Quality Craftsmanship

You can see the time and craftsmanship in the welds and the time they take to build the exhaust.

Thanks for the awesome feedback, Jason. Enjoy your new Evo X exhaust!
Impeccable Welding

The craftsmanship and quality of materials on this exhaust well surpasses mainstream brands and saves you money at the same time. Every weld looks like a stack of dimes. Highly recommended.

Thanks for the awesome feedback, Eric. Glad you recognized the craftsmanship and man-hours that went into the fabrication of these exhausts. Seeing the products online sometimes doesn't do it justice. We always strive to make our products look as good as, or better than what they look like in the pictures on our website- there's no smoke and mirrors like with some brands. What you see on our site is ALWAYS what you can expect when you hold our parts in your hand. Thanks again!
