gncc 400ex pipe ?????

[xcracer416]

i was thinking about switching pipes b/c my alien is way to loud for the GNCC and i was thinking about getting a curtis sparks full system. would it still be to loud with it?

last year at the texas gncc my 400ex sparks tested at 102, keep in mind it hadn't been repacked, this year the sparks on the 450r tested between 92-96 on most bikes. keep in mind their testing isn't the most accurate. if you are worried about it we made a quiet core set up for the sparks or you if you wanted to be sure your could get the hmf pipe and the quiet core.

Hope this helps
