Polini evo 4 exhaust

[woodsracer22]

Is there any exhaust besides the Mach 1 that will work with the evo 4. I know you would have to make a 3 bolt flange.

I used Hetrick's pipe. Made the 4 run really good. After getting the Evo 4 with Hetrick pipe, won 4 out of 8 races. Should have won them all. Broke axle, 2 broken chains and one getting flipped.

polini evo 4 is great motor. Polini makes a pipe for the evo4 that fits scooter with some work it can be modified to fit the quads, it doesn't have the power of the mach-1 but it does work real good.

we had the same set up with a mach 1 pipe made for that motor ,great set up all around power, i would just get a mach 1 for it. bedause when your child is racing your going to say wish i had a mach1, marc At hot quads spends a lot of time with mach 1 pipes getting these things tuned in , topends and pipes are like a married couple you dont want a divore it cost a lot of money in the long run and your not happy

on the real im wondering how the mach pipe will hold up to long term abuse??
and for the price thats the last thing to be worried about

we had 3 of them and our whole district had them and we raced two other districts and abought 90 % of the bikes had them , the older one s , the silancers came loose from the bolts , but the newer ones are way better and they are real carbon fiber, these pipes are instant bolt on horse power

We run Mach-1 pipes on all ourr quads now , 45 minute races and they hold great, no worries.
