youll be better off getting a custom one made for that price. comptech mufflers arent available anymore, but you can get other brand of mufflers for a good price. piping and labor shouldnt cost you more than 200. so i would say total 400 for a custom job.
I got the last of the comptech mufflers. I'm having a custom mandrel bent stainless exhaust done. It should be completed tomorrow. The cost:
$400 for labor and pipes
$95 for Comptech Mufflers
$62 for Comptech 4" Tips
