Rodneya Posted April 28, 2019 Report Posted April 28, 2019 Can somebody explain how different length stingers work on GP style pipes (both pipes exit on the same side on a road bike). I want to build a set for an aircooled 73 Rd350 I am working on. The inner pipe will have a much longer stinger than the outer pipe to get the silencers together if that make sense. Does the shorter stinger length need a piece of internal stinger inside the last cone to keep both stingers the same. Quote
locogato11283 Posted April 29, 2019 Report Posted April 29, 2019 They really need to be the same length. Both stinger diameter and length can play a role in RPM. Quote
Rodneya Posted April 29, 2019 Author Report Posted April 29, 2019 Thats what I thought. I remember a thread quite a few years ago of a member who put a banshee motor in a newer street bike frame and he had really long stingers with the silencers up under the seat, but I can not find the old post Quote
