TomRhere Posted October 24, 2003 Share Posted October 24, 2003 'Member reading that you would use 1-7/8" on an NA EA-81, and 2" on an NA EA-82, just can't remember where I read it. I used 2" in making mine for the '82 with the EA-82 in it, because it was real close to the exhaust port opening size, and sounded like the right thing to do. Can't say if it cost me any low-end torque, as it's the only EA-82 powered vehicle I've driven. Exhaust was shot when I bought the BRAT, so I couldn't drive it until I did the exhaust. I can say that I like how the engine feels while driving, compared to my '86 with the EA-81, even moreso with the Weber on it now. I'm going to get myself in trouble with the cops, ifin I don't stop mashing the loud pedal while running thru the gears. Just can't help it though. 2" duals, no cross connection, Xcelerator free-flowing Turbo mufflers. Gotta love it!!!!!!! Quote Link to comment Share on other sites More sharing options...
