Thanks for your concern ,i have talked to a few people and they do agree with you.So i have decided to start small and work my way up .

thats absolute crap. We fit john bowe, red back and herrod systems at work and still have them under warranty. we have a GT-P that comes in regualry from running rough, we have had that exhaust on and off several times and its under warranty. I'd dig deeper, cars arent cheap...they should sort it out for you. oh and as for the exhuast wrecking the motor, tell them to walk east, total crap.

The dealer may provide warranty, but Ford/FPV won't.
