My wife and I each have '03 Trailblazer 250's. We enjoy them a bunch, but I want to mod mine. We live in Colorado and usually ride trails from 7,000 to 10,000 feet. We do pretty tough trails with lot's of climbing, tight turns, etc.

I'm torn between HSP, HPD and Ritter's kits.

I'm looking to gain some low end without sacrificing the top end. I've heard the HSP pipe is VERY loud. In fact, I would LOVE to have the loud pipe, but I've heard HSP does nothing for low end.

I've also heard good things about Ritter and HPD kits.

Which one should I get? Should I call them prior to ordering to make sure I get the right clutch kit?

Blake, FYI the new hsp 250 pipe is over 12db quiter than our old pipe. It's still louder than stk but not near as bad aas our old one.

 

I have a 250 also and the best kit out for it is the reed conversion. My 250 has so much lowend with this kit its crazy. I dont think HPD still makes it, but AZBADBOYZ does.

 

Contact tooslow on the polaris forums. He has a trailblazer and rides in colorado at higher elevations.

 

I hear hpd pipes crap out quickly. Somebody quote me if i'm worng.

 

We live on the Grand Mesa and ride anywere from 7 to 11 ft my son has a 250 trailblazer that we had Bubba port (by the way its working great Bubba thanx) he didnt port it for all out top end but really wideend the power band we also put the HPD low end to midrange pipe on its louder than stock but not to bad also with the sparkarester silencer this thing works great in the mtns pulls real hard and will hang with my 500 Scrambler all day we still are running the stock carb but have picked up a 33PWK that were gonna try as far as the clutching I would contact Extreme over you way alot of the kits dont adress the high alt problems I know i pulled the Team clutc off my Scrambler because they dont have a set up for alt I'm trying some compound cut helixes that are working real good

 

I would go with the AZ BAD BOYZ

 

I ended up getting the HSP pipe and clutch kit. I got the white primary spring and orange secondary spring. The pipe is loud, but not as loud as I kinda hoped for. The clutch kit really makes the quad take off at a much higher RPM. Not sure if I will like that or not. Reminds me of my snowmobile. Still waiting on the KN filter and still need to rejet it.

 

Blake did you purchase the parts direct form hsp? Did you recieve weights and a helix with your clutch kit? I work there I just want to make sure you got all of the right parts, if you don't like the high engagment we can try and work around it but performance wise the higher engagment work the best.
