The chip I had it with Upsolute in Dallas and I had my muffler replaced with Magnaflow Part # 14220. Try the Magnaflow first then chip your ECU.....it'll make you fall in love with your Crossfire!

I'm working on getting my XFIREX lowered with Eibach Springs, brake rotors, wheel spacers and possible new 19" front and 20" rear wheels ( still trying to decide...I kinda love the stock wheels ). I found a TireRack store in Shreveport which is around 100 miles away from Tyler. That's where I'm gonna get my stuff before we can hook up....it'll be great!
