dont ever put a magna flow on a 4cly toy. nothing worse than taking your wheeler out for a drive and you sound like a ricer. don ask me how i know. 40 series are sweet sounding as long as you stick to 2.25 all the way out. if you cut it off before the rear axle the cab will always hum in side. glass packs are for people on the cheap nothing else i have changed my exust so many time it hurt to think about. if you want performance get a the new flowmaster crawler series and a high flow cat great sound but not over powering.
