Best sounding exhaust on the market today!

This product actually is on my 2015 STI - the installation was quick! All the tubing fit right into place easily, with the OEM hangar placements.

I’ve had this exhaust on my car for probably a year now - and it makes my STI sound like no other STI I’ve heard. It’s subtle yet when it comes time to WOT, that’s when she really sings!

The Carbon Fiber tips look absolutely stunning on this car - and for the price you get a lot of bang for your buck ;) I would highly recommend this product!
