My favorite exhaust

I've ran a tomei extreme ti catback before and I enjoyed it, however I felt the need to get out there and try some of the dual exhaust set ups, cut outs and whatnot. In the end came back and bought a brand new Tomei to install for my tune. The sound quality, the weight, the overall look it's all amazing and then you get to the price and if it's not on sale you're kinda like mehhhh noodles until next paycheck is okay because you bought something that'll make your car look and sound good!

this exhaust is as good as it gets, people. easy to install, perfect fitment, looks sexy as hell with all the burnt titanium goodness. 11/10 definitely recommend. I have it paired with an ets race test pipe and ams downpipe and sounds like a damn monster. my neighbors hate me by the way :) and since installing it, I don't think I've turned on my radio. it's that good to listen to. throws mad fireballs too

I love the sound of this exhaust. Its extremely light weight. I can't wait to get the test pipe for it.

Looks great, sounds great, and it weighs less than the packaging it comes in! Fitment was excellent and because of the clamps you can twist the pipes to get it just right. Highly recommended.

  • Q: Tomei vs Greddy Loudness  Evo_X_FE 2 years ago


    I am considering this exhaust vs the Greddy Revolution RS for a 2015 Evo X. Do you have any sense on which exhaust is louder? I'd prefer to add some additional volume to the stock exhaust, but not get something so aggressive that long distance drives become unbearable.

    • A: The Tomei will be a bit louder than the Greddy Revolution RS because it does not have a resonator. This Tomei Expreme Ti catback is one of the loudest catbacks that we offer.
