You have to be INSANE to have long-tube headers on a big-block A-body Mopar!

I used to drive my cuda with 3" exhaust to the races, race it, then drive back, 100 mile round trip.....I'd get home and my head would be ringing even the next day. At the time I kinda thought it made me a Warrior/Badass/Bad Dude but now I look back and have to admit it didn't do anything but make my head ring.
My Dart was the same story. Would drive to track and back. I got fed up and welded up new pipes from headers to tailpipes adding huge 3" Chevy Suburban mufflers. Now I can hear myself think. I have flanges at the tailpipe so if I want I can put the old X-pipe with the Racing mufflers on in about 30 minutes.
