Best exhaust for the money

No to bash products i had a hks carbon ti installed before the stm, perrin test pipe and map o2 dump also, the hks was quiet but just lacked the aggressive tone the evo should have, the stm ss gave it that mean sound deff not overly loud just righf 10/10 would buy again

Glad to hear that you're happy with your STM Cat-back exhaust, Andrew! Thanks a ton for your awesome feedback.

Exactly what i was looking for!!

Had been holding off on buying this and I don't know why I did, because I love it!! I'm currently running the ultra quiet resonator and combined with the quiet muffler on this exhaust my car is not too loud at idle. Which is what I want as the car is my current daily and less attention in SoCal the better. However, when I go WOT the exhaust comes to life with my STM open dump! Great craftsmanship as always and it was such an easy installation. Thanks again STM!!

Glad you're enjoying it, Joe! This is exhaust is definitely one of our favorites, and it sounds like you have the set up all dialed in. Let us know if you ever take any sound clips, and we'd be happy to share them on our YouTube/ social channels.
