Guys'
It would be very helpful if anyone with good solid data & specs would stop in this site and list what they know.
An example: the grom header pipe is 23.5mm. Is that inside or outside dimension, I'm guessing outside
Anyone in Japan or Europe had a cylinder head off, what are the valve sizes?
Someone who has a removed OEM exhaust system could take a bunch of measurements
I just ordered a pile of steel tubing "J" bends, to start making a non cat lower pipe
The prototype will be steel, and the final stainless
Any info that is accurate, I can put into my computer programs, and start to figure out what is really needed.
Help!
