Bottom or top??

[krt400ex]

O.K. I can get a sparks full system for around $400 brand new. I was told this pipe gives me more on top. I want more off the bottom as well as more throughout the power spread. Does this pipe add bottom as well? And does the spark arrestor and quiet core really make it quiet.

The 400ex is plenty good on the bottom, a sparks pipe combined with a stage 2 hot cam, or even better yet a HRC cam, lightened flywheel, a stock bore 11-1 piston and gearing for your area will have you ripping up the 450's.

I do not know of anything that will quite down a sparks....or any of the race series pipes on the market.
