Another pipe Question

[RideRed400StYlE]

I am going to be racing MX, and I wand some more low end and mid range power, I posted about a ct pipe earlier. but I was reading up on the hmf on here, and it sounds pretty good, so once again can I have everyones Input on what would be best for MX

HMF
CT
TC
Curtis Sparks
Or any other reccomendations?


This would be a great help, also I have an XR cam, and Curtis sparks ignition advance key on the way if that helps. and I am putting an FCR39mm carb on

I have a Curtis Sparks X-4 complete system I'll sell you. It's like new.

Sparks, TC, Duncan, CT, LRD, Hetrick`s. Any of those Pipes will be Good.
