Let customers speak for us
from 239 reviewsHave had mine going on 2 years now and looks great, especially now that I have the Stillen Strut tower brace.

Changed the whole look of my car and the material looks even better in person . Super durable I highly recommend

Took a minute for them to make it, but it sounds beautiful. You can hear the turbos spool up and the rumble of the VR30 engine. The metal has a weird frequency resonance with 2500 and 5500 RPMs where it gets louder, but I personally like it. I've only gotten compliments from the sound so far. Also, the tips poke out, so it looks incredible compared to stock exhaust.

Easy install, zero issues on 24 trd OR. Works great, noticeable difference.

Defuser looks very nice. gives my 2020 maxima RS Nissmo the perfect final touch.

Great product! Works as described.

Great fit and finish and awesome sound. Only recommendation is to weld it together or have someone do it as the supplied clamps aren't great and could cause leaks over time.

Came as advertised - packaging was thorough for a delicate item. Shipping was a bit expensive.

Night and day difference from the stock air vent, improved throttle performance, IAT drops significantly quicker. Paired this with an aftermarket oiled air filter and have seen vast improvement. Others have mentioned an increase in MPG but I haven't had the scoop on long enough to get through an entire tank of fuel. 2023 GMC Sierra 1500 LZ0 Duramax.

The minute I started it after getting it installed I loved the roadie and meteor sound and it was definitely not overdone. It's the perfect amount. I love being able to hear my RPMs go up and down and it's not too drone by any means I also noticed a little bit more Kick when driving it.

Deep tone, great looking under the truck and easy to install! Also you can really feel the extra horses on the throttle!!

I bought this thinking it wasn't going to do or change much, but man this makes driving my maxima so much more fun and smoother!

My wife and I bought a brand new 2024 Z knowing that the stock exhaust was terrible. Almost immediately, we ordered the Stillen Comp exhaust and absolutely love it.
Totally painless to install and a WORLD of difference. Listen/watch the comparison videos - Stillen is the way to go. Even the guy that installed it said it was one of the best sounding exhausts he’s installed.

I loved this product, i wish it came with rubber grommets to bette protect the metal
