I bought a new 800 classic and put new pipes on it (cobra 2" drags) and was wondering if this would increase the HP or torque, or if would decrease anything?? Thanks

re

sorta depends on what you do with the intake,if you open the air box up with a low restriction filter, or other mods(hypercharger) the gains are noticed
in mid-range rpm's and hp/tq get a little boost,but i've seen hp drop some with dragpipes alone - letting more exhaust out without increasing airflow
can rob horsepower on anything-if tuned good after exhaust/intake mods
the 800 will perk right up :shock:

if the baffles are out of them, you will loose some low end torque but you will gain in the mid and hi range as you get more air and rpm's in the motor.

I forgot to dig up an ancient thread and comment on it while my post count was in the single digits :oops: . So I guess I will do it now and get it out of the way! BTW, those pipes should be pretty cool! Show us pics when you get them installed.:wink:
