I have tried the stock muffler, and side dumps from Abell, Bennett's, SPE and even tried a Mac's header pipe with a mousse can muffler which gives a real performance boost but is extremely noisy. So far the Bisson side dump for the G23/G26 with 16 cu. ins of volume versus between 5-8 cu. ins for the rest, and which has the same mounting dimensions as the G20 seems like it could be a very good choice. Has anyone had any experience using this muffler??
