Exhaust ?

[Pimpin400ex 15]

I just put in a dynojet and put in the jet you need if you have an aftermarket exhaust but the only problem is that I do not have and exhaust and I need feedback on what works well and sounds great. If you can tell me which one gives the most horsepower that would be great. Thanks.

sparks is my first choice and hetrick and lrd tie for second...all 3 r great and u will be happy with any of them

if u want to see test on websites try these 2: http://www.atvnews.com/output.cfm?id=30961 and http://www.dirtwheelsmag.com/detail.asp?id=181. Hope this helps a little.

Thanks so much, and only one more thing, Cost Efficency. Right now we are looking at HMF because of price, is it good?

hmf=great pipe...good midrange hit...average power...if i was u i would spend a lil more to get a lil better and higher quality pipe...like the sparks lrd or hetrick

Do you know any sites with Dyno tests on the Sparks pipe?

I havent heard to much about lrd, and i dont know any one who has one. If you do just reply and tell if its good.

one person on here has one and he loves it. he had a sparks x-6 and he thinks the lrd gave it more power everywhere. i think he is running a built motor. i have the sparks and i like the pipe. no pipe on a 400ex is going to give arm pulling power differences. i have no personal experience with the lrd myself.

he ran both pipes on the same EXACT motor? im running a sparks right now...and when all i had was a pipe i raced my friend who has a lrd and i KILLED him..i mean not even close and that was over 10 drags or so...so i am sticking with sparks they havent done me wrong sept the filter...but ill get over that
