The pipe did a little bit on acceleration on my China girl, not much for my overall speed. Which is fine, it’s actually quieter than the stock exhaust. Is there a muffler out there that you might recommend for better performance? Many of which I find say they do a lot, but come to find they’re just as you said, fancy.
currently I actually moved the needle down one thinking that would fix it, so I probably made it worse with that, it’s 1 notch above the lowest setting. I’ll raise it up to 1 notch above half (where it was originally and had issues at full throttle) and see what happens there. Also no altitude stuff lol I’m in Wisconsin.
