header bolts

[bets400ex]

all new to this so im wondering what grounding down header bolts is all about as for performance wise

[coryatver]

it makes it so you can't get your bolts to tight and lets a little air leak out at the header so you make more power:eek: seriously though I think you are talking about grinding the weld off in the stock header. it lets the header flow better maybe get an extra hp

[bets400ex]

is this for the factory header or aftermarket?

Factory, go take your pipe off and look at it
