I got a quote of $400 from Momentum, but it sounds like they tape and wire tie instead of welding in a straight pipe. They also leave out the fiberglass. Not sure if that's the best way to do it, so I'm looking for a shop, too. Otherwise I may go for the Eisenmann Sport or another aftermarket exhaust.
