I bought a really clean 76 GMC C15 (250 6 cylinder, three in the tree) last year, and the only real issue with it was the exhaust system. Both the cat and the muffler were shot, so I eliminated the cat and ran 2.5" pipe from the take down pipe through a Summit Race muffler (2 chamber). I wasn't happy with the sound (loud) so I installed a Walker Tru-Fit muffler. That helped a lot (nice sound at idle) but it is still too raspy under load.
I know an inline 6 cylinder will not sound like a healthy V8, however, this setup makes an otherwise nice truck sound cheap. Before I waste any more money on mufflers, anyone have a thought here? Would adding a glasspack muffler act as a resonator? My current setup has the exhaust dumping in front of the rear wheel. I'm sure that is part of the problem, with the tailpipe kinda in my ear but I am looking for a simple (cheap) solution.
