Motorcycles don't have exhaust manifolds; the headpipes bolt straight to the head with 2 studs per pipe. Never seem to give any trouble. Of course it would be possible to MAKE a headpipe fitting (preferably in stainless) to be permanently bolted to the head, with headpipes attaching to this, but it would be a custom design. -- Andrew Grebneff Dunedin New Zealand Fossil preparator <andrew.grebneff@stonebow.otago.ac.nz> Seashell, Macintosh, VW/Toyota van nut HUMANITY: THE ULTIMATE VON NEUMANN MACHINE DEMOCRACY: RULE BY THE LOWEST COMMON DENOMINATOR |
