Clubman exhausts...
Soosh my mate Tavspeed (he's on here) has a BGM think it's a V3 he replaced a Saigon Taffy with it, I've a Micron on think it's based on the DJ...read that on here maybe from one of Dave Webster's friends a few years back. But that old RS44 is still rock solid! When it was on the bike people used to say why don't you get rid of that standard pipe and put something else on? As tailpipe is so narrow unlike AF ones it looked like a standard box pipe...that was until it fired up and they wanted to know what it was lol (sure you already know all about that pipe though).
Hendy that pipe would almost be an old under kickstart Fresco hehe...reasonable grunt and decent mid range. I've an ADS3 to try on another engine, can't say I like it's looks that much, but it's supposed to pull very tall gearing with ease while only revving to 6k.
