What type of exhaust system do you prefer

 

Maybe 5 years ago there was a good article on pipes. I think it was in ATV Magazine. They tried several pipes from different manufacturers on a single quad to get a direct comparison between them. Some had less power than stock. Some were worse than stock at one part of the powerband and better than stock at another. 1 out of 10 pipes was better than stock through the whole powerband. It gained a whole horsepower. Big @#$%^& whoopee! The other 9 out of 10 pipes sucked but some people thought they sounded better than stock. Why spend that money just for the sound? If you aren't doing any mods to it putting a pipe on it is nearly useless.

 

That really depends on the bike, where(being a fan of dyno charts even though you can always trust the results) many will run much worse untill you dial in the rest of the motor to handle the extra breathing room. My KFX 400 benefitted greatly from a White bros. E serries with a YZF style turn down tip, it did even better because I made sure the jetting was spot on and had a UNI filter on it. some companies do only focus on sound, so just do the research before you buy. Heads up all 2 stroke quads benefit from anything but stock.

 

Motoworks all the way...... the new guys on the block have really figured some things out....

 

if it for a 4 stroke a vote hmf im its a 2 stroke i vote fmf
