I agree with those that say 4000-5000 for an exhaust is ridiculous!! My thing is weght. I took the stock muff pack off to anaodize the heat sheild and almost threw my back out! I couldn't beleive how heavy it was. Some where on here is a thread about shelling the stock muff pack. Atleast taking the cats out. I want to loose weight on the bike and spending all that money the cost per pound is WAY out of line.
I don't know if that will screw up the ECU, everything things else seems too!!
I want better sound but I would rather lose weght on the bike. And no I'm not a big guy. I just have a fetish about taking all that crap off a bike that does't lend itself to better performance!!
