I finally got dual exhaust installed yesterday on the Bonnie. It looks cool, sounds cool and hopefully will increase my gas mileage. Lots more jump off the line too! Now I think I'm done with the performance parts (except for some small stuff). Put money into necessary maitenance ( fix rust on doors, refill AC, new rad soon).
I guess you kept enough back pressure from the flows?
When I dualed mine I lost some low-end but gained a craplod of high-end. Instead of my acceleration peaking at about 10-25 it peaks at around 40-60 now, I haven't really opened it up since I screwed the engine.. :/
