pipe on a 300ex

[quad_racer_19]

i want to get a pipe but i dont know if it would be worth it, sure it would look good but can you notice a differentce right away??? is it a huge difference???

i heard it only ups it by half a horsepower????:confused:

most pipes offer between 3-7 horses..its worth it..also add some jets and an airfilter and you'll notice a pretty big difference

The FMF pipe on mine was almost twice the size of the stock one and it had a lot smoother of a bend for better flow. Don't forget, these motors only put out 17-19horsepower to begin with. So if you do a mod and it only adds a 1/2 horsepower or more, you'll be able to tell.:devil: You'll also gain some speed on the top end, because of the motor breathing better.

You may want to try posting this in a powertrain thread, might get a lot more replies. Good luck.

Hey dannyf how do you like the 400 carb on your 300?? I'm in the process of a little bumping up on mine & was thinking about a bigger carb but was surprised @ how big the stock one is really.

I like it a lot, I kept my stock one and just retted it every time I did a mod until I got the the head modified by Sparks. That's when I figured I'd better get a bigger one to help it flow better.
