Aftermarket Header Reliability

[Turboflash]

For what it's worth, I have been told by a very reliable source, that he has moved the same PEFI header 3 times as the owner had acquired new sleds; from one sled to the next to the next. Not sure the total hours or miles but it was over 3-4 years of normal riding. Original header still good, no issues, no cracks, no problems with bellows, etc.

A few years back,If I remember correctly, Sandale dyno tested all the headers available while developing their own and some performed much better then others...trouble was Sandale never made their findings public.

I bought a Sandale Terminator header years ago. It was a very nice piece and made good power. Running TD tunes, it had a little lean stutter at 25mph, which is too slow for the closed loop to fix. I never spent anytime at that speed and rarely noticed it, but when I would let my 5 year old drive the sled, he found it annoying.
