The HO model is designed more for engines bigger than 103. I would go with the standard Propipe. I've used that one with great results. Will the HO fit your bike, yes, is it the best choice over the standard Propipe, no. I just looked at the date too, this one has a new life since Nov 11 I guess.

 

will it hurt anything to run the HO pipe on the smaller 88" engine ?

 

can it be any worse than drag pipes ?

 

Put it on my 103" with some Woods cams and a PM intake and PCV... runs awesome.. Ran well enough without the cams I had a few second thoughts about doing them, I'm a fan of the HO ProPipe...

 

i love the pipe too just want to make sure im not doing damage by running it

 

2-1 pro pipe did many things for me
1) stop the burning of my left leg
2) bike runs great and better fuel mileage 165 miles per tank to 210
3) install quite baffle and now I can hear the radio
