ok guys i need some help i have a 99 scrambler 400 4x4 and i love trail riding and going through mud, also steep hills but i love to drag race also...i am going to get the hpd trail pipe and either an agressive clutch or standard i want to be able to pop wheelies also do yall think the standard would do the job...it is about $70.00 cheaper...you guys have been so helpful lately thank you.

 

as a rule(not always though) you dont have have the best of both worlds. i know w/ the h/c kit, it says on the site that you can adjust it for torque or speed to maybe that ways the best to go. if you have a high engaugement clutch setup i dont thinkit wouls be good for hard trails, but thats just my opinion.

 

On a 400 you need to clutch to the pipe.Which means a higher engagment and heavier weights to bring it down some.Your goal is to get to the SWEET spot of the pipe as soon as possible and stay there.
This is one reason I recomend the Dynoport pipe to trail riders over the others.
