im stuck between 2 full exhaust systems....the yoshimura comp full or the DMC alien exhaust with the spark arrestor....

i kno the DMC is more BUT it claims 7.5 more horsepower and like 21% more torque at so many RPM's (i forgot)
and i got a friend with the DMC on his raptor and i love the sound and the performance

i have absolutely no experience with the yoshi

 

Well i see noise is no factor DMC's are loud. I wouldn't go with either. HMF seems to make the best power but its loud. 8hp gain 5ft lbs of torque.

The HMF also looks alot better IMO...

 

hmmm i guess i never considered them


i have the WB slip on right now

 

I would hope people would stayway for the loud pipes to help keep the sport going. I know here it is a big deal. At are local race track they are not allowing anthing over 98db on the track.

 

Why don't you call up Doug Nicholas www.nicholascycle.com he's right there in Iowa......he'll tell you which is fastest....and it's none of the above. [img]i/expressions/face-icon-small-smile.gif[/img]

 

hehe i know cus ive been down there and hes told me what is fastest, the ones they have right there in the shop are damn good.....but i was just curious if u guys had any different ones

 

what one is best my friends have the white bros. and hmf of which the hmf seems better.

 

Plain and simple, you want power and aren't worried about noise, HPD is the pipe. (Some say the HPD pipe doesn't look real good too, just a factor to consider, I personally don't care) All others, in my own opinion, are the same performance as the wb/pure polaris pipe, but they offer a head pipe.

 

I brought the w/b pipe when I got my new bike. When I rebuilt the engine this winter I brought the hpd full pipe. It's awesome and I looked all over for that cheap and poor look???? If it's not pretty why was everyone in love wy the look and sound as run it down the track lol. Maybe people that can't afford it call it cheap because it's easier than being honest.
