Just thought I'd put out a quick parts warning:
Part: Shorty Headers (application: All E36 non-M/Z3)
They are sold at www.bavauto.com
(Part: 32 E36 OBD-II C) and http://www.mmotorwerks.com
Product info states: "Our headers are designed to bolt directly to your engine and stock or aftermarket exhaust systems."
Although I was told it would hookup to my stock exhaust, it took 13 HOURS of custom modification work to get them to fit on. Obviously I can't speak for the other models this part is offered on, but I can tell you that this was the case with my 1996 328IS
As far as the good news....I'll post up tonight and let you guys know how it sounds.
