best exhaust

RJ86 · #1 (**permalink**) 10-09-2009, 01:29 PM

Have a 08 ds450x and I am looking for the best exhaust that works with it. I am looking at FMF but I just want to if there is any exhaust and programmer combos that work really well with the ds.

No dyno testing have been done on all pipes for the ds450 to see which one performs the best. Alot of people on here will recommend the Motoworks for exhaust, I would also get a Dynojet power commander to go with it.

the hmf is good too...heard the ron woods is the best...a lil loud tho. def get the power commander if you dont get the motoworks package. dont touch the other ones lime moose, fmf or whoever...and dont touch the fmf pipe. its garbage.

A guy from work installed a Rossier Eng to his quad full kit and man it made a big diffrence. That company dyno tunes there stuff.

The motoworks pipe that the national guys use. Its 96 db. It also apparently makes more power than the regular system.

motoworks, rossier, ron woods, yoshi, hmf, but I would not get a fmf

I had a yoshi & was surprised how much it helped, fmf seemd to help some but still did not help the low end

You can buy only steel/aluminium motoworks exhaust. I think it'd be better to put something with less weight than stock. Which exhaust is available in titanium, is 96dB and is comparable to motoworks?

I would go with whatever pipe you want and do the pink wire mod. The 08's have a built in race map on the stock computer once you do the pink wire mod that enables the race map.
