i believe FMF makes a pipe for outlaws. https://www.partsforatvs.com/default...Q+OUTLAW+POWER

i'm pretty happy with how my 500 runs, but my buddies 525 will eat it alive...
as for MX, i dont really get into it, i do more trail ridin n IRS is so much better for rippin across rough terrain. i've got 11 inches of ground clearance in the rear vs a straight axles 4. n i dont have any problems makin it slide.

 

i have a ltr450 with some mods. i have a trinity exhaust. if i were you i would go with a hmf pipe they sound good.

the sad thing is that i have more money in my quad then my truck

 

My buddy spent about $6500 total on that white 04 450R including price of the quad. My 05 black one there had about $5500 total, including price of quad. He got his quad a LOT cheaper than mine, but both still pretty inexpensive considering the hardware.

Those 525 KTM motors rip! Is noise an issue where you ride? What type of riding do you do?

 

hmm noise, NOPE!!! I want loud as $HIT no noise isnt an issue i like loud. and most of my riding will be screwing off, i wanna make that puppy scream but im way to damn big to ride mx

 

Too big for a fast quad? Try a Polaris Sportsman 850 Touring. Its a 2 up quad with over 800 cc, it's a monster and FAST.

 

im not sayin im big like fat and huge but compared to them lil bastards that ride, im big

 

I'm over 220 with gear on...

I'm all for loud pipes over here, but just so you know, loud pipes are like the black smoke of the diesel world now, cool to have and do and see, but usually shunned by other riders/drivers in the community.

HMF makes some nice slip ons at a relatively inexpensive price.

Are you looking for full system or just a pipe?

 

hell i live in the middle of no where and wanna be heard . and im not sure, which is the best?

 

I hate wearing EARPLUGS, cause some guys run open exhaust Nice & quiet is the way I like it, cause you can talk to your friends as you riding
