HMF or R4

[400ex Ride Red]

I have a white brothers r4 slip on and I was wondering if it would be worth it to buy a HMF slip on? I see lots of people on here seem to have it or think it is real good so I thought I would see what you guys think.

most slip-ons give almost the same power the main difference is mostly the noise level.

if u do get an hmf how mcuh for the r-4:D

i have an R4 and love it, although it louder than most. The only problem with the R4 is that White Bros. discontinued it. I would say keep the R4, its not worth the money for a new pipe. Spend it on something more important.

If I were to buy the full system a HMF would be a better system than the R4 wouldnt it?

had the R-4 slip- on with 155 main, nice torq, sounds great. Switched to full HMF with 170 main, needle in 3rd pos. from top 40 pilot 2 1/2 turns out. UNbeleivable power & torq gains. U won't be unhappy with it.:eek2:
