['68OrangeSunshine]

I used to run 2 Weiand steel packs. Sounded mean. I was a college kid so I had no bread for muffler shops: I just wedged them over the collector ends of both headers, and held the aft end up by baling wire [or coat hanger wire] wrapped around the trailing arms. Rough RR crossings were my bane. I once dropped one --when the baling wire broke-- on the street and backed up to pick it up out of the road. A squad car passed my by, they were laughing their @sses off. I was lucky they didn't bust me; it was about 0300, IIRC.
Later in the '80s I went whole hog at the 4x4 fabricators. I had them resurface my Clifford headers, make up a cross-over pipe [more like the Russian 'N', than an 'H'] after the trans and splice in a pair of turbo mufflers with 1-7/8 tubes exiting behind the rear tires at a 45* angle so I could look at the exhaust color thru the WC rearviews.
Still set up like that.
