well good luck; to each his own i guess. but i think you would do better if it was a true 'bolt-on' system that included all the pieces. universal mufflers are alot cheaper than $275, and if the person still has to cut their factory system AND has to buy tips to weld (or clamp) on, it doesnt sound like a "kit" you're selling.

my own $0.02; again please take this as 'constructive' criticism.
