Here we are "exhaustively planning" the next stage of 1970 Honda N600 exhaust refinement. The old straight pipe full length exhaust system was a little raspy, yet flowed really good and gave the 2 cylinder 600cc a nice top end kick. This new 1.5" baffle pack temporary exhaust system offers a tad more torque, has a nice deep tone, but is very short, just temporary, and feels lazy on the top end.
