Pypes exhaust

I just ordered a set of Pypes Violator along with TTI's for my 383 Dart. I read on one of the boards that the system was intially designed with a 68 383 Dart with 1 3/4 TTI headers. I wont have time to install them for another month or two, but I'm quite confident everything should fit reasonably well. Great deal for mandrel bent 2 1/2" x pipe stainless! Might want to "search" over at Moparts or Big Block Dart sites. PG and BE&A have the 2 1/2" & 3" Chrome exhaust tips aswell.
