400EX Line Bored Header With Custom Chromed Heat Shield
This is a TRX400EX header off of my show bike. The header has been bored at the head end to give it 18% better flow. These come from the factory with a giant weld restricting the flow. By boring and polishing it, you will get better throttle response and more top end power. A must for someone that has a slip on exhaust!
what do they mean by line bored and the weld that restricts the flow? how would i do this to mine?
