Sparks X-6 on stock motor?

[the-ex-files]

Would the Sparks X-6 complete exhaust, do any good on a stock 400EX? I wanted to get a exhaust and heard Sparks was the best. But I also heard there can be too much back pressure. Does anyone have an X-6 on a stock motor? Gains? Or would I be better just getting a slip-on,because I probably won't do motor work for awhile. Thanks!

the x-6 performs just fine on a stock motor. you dont need to worry about the back pressure issue. you won't really gain lowend power with this pipe on a stock motor, but the gains from midrange to top will be nice. don't waste your money on a slip on as you will be regretting it later if you ever do engine mods.

the reverse megaphone x6 is awesome for top end.
