Got got a Zoomers exhaust system cat-back. Sounds awesome. I hope to see some gas milage performance as soon as the engine chip recognizes the exhause flow.

I've ran exhaust's on pretty much everything I've owned. Haven't really seen that big an increase in mileage in my trials though. That includes adding a K&N filter. What I did notice was an increase in pulling power. Seems to "hit the hills" much better. I have a 1999 Chevy Suburban 5.7 vortec 2wd. I put the Magnaflow catback dual on it. LOVE the tone!! Sounds GREAT around town, but quiet while traveling down the highway!!!
