R1100S Exhaust accelerator

Postby HarrisBikeNut » Wed Apr 04, 2018 5:14 pm

Came across an exhaust accelerator kit for the R1100S on the Pelican Parts site. Made by San Jose BMW. Looked well made as is the air filter housing I've already got fitted. Wondered if anyone had (has?) any experience of this bolt on? It is designed to smooth gas flow into the headers by all accounts (keep the gas speed high to aid emptying?). Is. It proven or more witch doctory?????

I saw these some years ago Bob and I remember thinking that although they could in theory make a small difference they also add weight. I don’t recall anyone on any forum ever giving an opinion which I think says it all!
