Cheers chaps, I have done a bit of reading up about engine specs and pipe sizes. I cant remember where I read it but somewhere, it stated that with a standard 996SPS lump, it was thought that the 50mm headers were slightly too big. Im sure that with me riding the bike with the 50mm system, I would be unable to tell the difference between 45mm and 50mm. I am sure that if a 996sps engine was tweaked then it would need a bigger (54mm ??) Anyhow............................... Ok chaps, thanks for the help. Im just gonna have to ride it and see sometime in the spring when its all finished. DC. |
