Another great addition to your exhaust!
This ISIS product is great quality and super affordable. I used this to maintain stock emissions in my state and add to my ISIS street exhaust and down pipe combo. Turbo lag doesn'texist and the tone is aggressive but not annoying, even at highway speeds. The other noticeable difference is a nice RPM hang while decelerating. Great product! P.S. Called BTR and tech adviser was on point for my setup. Thanks!
