near the end of my to-do list ... along with a myna/mencken pump, straight-pipe exhaust ...
anybody with experience?
Sounds like you bumped the pump pretty good, so you'll want to go with bigger and better flowing exhaust. My engine is stock '84 300D but I replaced the entire exhaust with a stainless steel straight pipe , no muffler or resonator. It is 2 1/2 in. to the axle, then 3 in. to the bumper. Gave me lots more upper end performance and sounds like a 6bt cummins! Actually too loud, so I made a resonator after the downpipe and it took it down a notch. Tig welded sanitary pipe from the scrapyard. You probably should go 3" or larger. I couldn't imagine the price for custom s.s. headers but sure would increase the flow .
