The link to Andy W.'s install re: SHMs.I had the MSDS and went to SHMs. Butt dyno says SHMs provide power throughout the power band.
Warning On top of the $1200 or so price tag, I would send them off to be jet hot coated.
Here are pics of my SHMs after about a year:
They are probably much worse now, but will be removed and shipped to be Jet Hot coated.
IMHO, bang for the buck - no way. I think people are better off Jet Hot coating the MSDS at half the cost, and spending the remaining money on other mods.
