Back in the day we put those lightweight glasspacks on everything. Purple Hornies, Orange Goose (or something) Thrush, Cherry Bombs, etc. The tailpipes were 1.875, and barely adequate for a slanty; but when you stomped yur 340, she was barking a mean tune. Noise laws? IDK I ran straight pipes. Got off with warnings.
1.875 straightpipes are not that loud until second or third gear when the engine starts to really work. Mine were off the collector and under the rear axle, I mean steer8.
IMO nothing sounds as good as a LONG 3-pass muffler, stuffed with fiberglass, and terminating in turn-downs at the back bumper,like a Walker/dynomax/type. Then just stomp yur Hi-compression 360 and wind her up to 7200, and keep her there , spinning the tires to oh say 65 mph,lol. Stop, turn around and go again, but you better beat it after the second time......
