very nice....just what I was looking for.....thanks

The top end is better as well.

Since I recently discovered my 525 had wrong head gaskets, questionable valve springs, bent bolts, missing pleniums and a blown head gasket pumping antifreeze into the oil..........I'll attest to that. I'm surprised it didn't grenade itself right there!!! We did a full blown inspection and all the bottom end is groovy (except for main seal) and the heads survived as well with only a little corrosion. Went ahead and changed the springs, I'm told that's the only weak link on the motor.

To confuse more potential customers, see what happens when you put sport tubes or sweepers on a 500EFI.

The additional MPH gains from the CMI's will depend on a few other factors. Call 661-295-7000 ask for Bob, he has done quite a few lately and should be able to help.

If the hp500efi is stock, I doubt you would see any gain from going from stock headers to the sport tube, or others. The restriction with the hp's are the heads. Not the intake or exhaust.

From what I have been told by many.
