I have the Alien system, it makes good gains, easy to installed and looks good. i hear they have really good customer service too.

 

i got the full gyt-r system, awesome gains and sound but the spark arrester is bogus it pops off within a couple of hard rides.

 

Does anyone have the white bros carbon fiber pro? Or know anything about it?

 

LRD better low end torque with the same or more hp in the top

 

Mod the cam, get the GYR-T kit and you'll be set if not, go with a pro circuit pipe, screw yoshimura your paying a lot for name, do a whole exhaust not just slip on

 

Hi im new to the forums but I have a DR.D pipe and thinks its one of the best.I had procircut,LRD and hmf and my yfz pulls harder with it

 

Yoshimura TriOval Titanium ..... only $620.00 full kit on Rockymountain ATV.

 

I just bought a Dr.D slip on and it is an AWSOME PIPE and it came with a 172 main jet and a 48 pilot and the directions told me to put the needle on the sixth position did you put the pilot jet in as well as the main?

 

i run a yoshi on my 05 the main jet is a 172 and the needle postion is #6 now and i removed the air box cover awesome difference in power

 

hey is the sparks racing exhaust to loud??? just wondering also.... does it sound good??
