I have a 2006 lowrider with an 88cu twin cam and have just picked up a set of Hooker troublemakers that were fitted to a 2004 twin cam and after checking the pipe dia. when I got home I find that the hookers are about 10mm less in dia. Before I go to the trouble of pulling off my old set of pipes can anybody tell me if the exhaust ports on the 06 engine are larger than the 04 engine
Cheers
Chong
