I was wondering if anyone has a t-4 setup on there p650 or p700. I would like to know how you like it and if possable how it compares to the IDSX supertrap. I have a supertrap on my p650 and I think I would like to try something different on my twinpeaks if it ever gets here.

 

I have installed the PC T4 on my P700. I cannot compare to the IDSX. But I can compare to the MBRP. Look at it this way, I cannot see how any silencer that is designed by either a mutli-chamber(reflection-cancellation) or a Disc setup can flow well up on top(higher RPM's). Maybe some one can explain this to me. Yes, they are quieter, but more restrictive than an OEM system. How do I know this....No matter how I jetted(rich or lean), I lost 3 mph top end using the MBRP. Sounded good though. I took the MBRP off and returned the jetting/exhaust to stock. This restored the my original top speed. The PC T4 gained an average of 2mph over the stock OEM system. I hope to dyno tomorrow.

The T4 seems to be the way to go if you want the most HP gain. However, I would not take your ATV hunting with this pipe installed. I don't hunt.[img]i/expressions/face-icon-small-happy.gif[/img]

 

What jet's did you go with when you put the Pro-Curcuit on???????

 

Stan, where did you get your T-4 pipe and did you go with a slip on, or a complete system. I have herd people talking about the T-4 for the prarrie but have not seen it offrered anywhere ex. rocky mt and other catalogs.

ps. thanks for the help

 

BTO motorsports still has the best price for the full system. This is were I bought it from. Of all the systems out there, and the research that I've done, the PC T4 is the way to go. Well, at least for me. I wanted more midrange and top end. This pipe delivers. I was supposed to dyno this weekend. I got side tracked cleaning my garage for winter and installing the plow on my P700. 148/145 mains are in there now. I still think the motor wants a little more. I'm not going to change them again until the dyno verifies the A/F ratio and the RPM max HP occurs. I think I have my clutch set alittle to high. Its still impressive for a 4WD tank.

I went to the BTO web site and fond were they list a T-4 for the 02/03' p650's, does this one fit the 04' p700's and does it come with a head pipe or just the muffler. The price they had was 395.00 I am guesing that would come with a head pipe for that kind of price. I am also wondering what end cap you went with down spout or cone type. I am not sure what the difference is.

 

The P650 pipe does fit the P700. This is what I ordered and installed. I believe they (Pro Circuit) changed the design of the silencer from the standard motorcycle tip to the Euro design. I was expecting the latter but got the Euro type...like the T496. The end cap included, with the FULL SYSTEM, was the 1.75". No need to order another. The core itself appears to be 1.75". Going to a larger tip will do nothing...on the newer Euro can. Going to a smaller 1.5" may quiet it down some but it would be more suited for lowering the power band alittle. I think the P700 makes enough low end HP. I had all the optional tips ordered then cancelled after installing and re-jetting. Sound is nice. Looking at the plugs right after a 68mph (66mph stock) run down the street, the current 148/145 jetting is close. This is for my setup. It may not be what your ATV needs. Elevation, ambient temp, track pressure, air box mods...all have a factor in this. Just remember, you have CV carbs. Don't remove the lid, or cut holes in it. Too many people confuse these with RS or FCR's(flatslides). Probobly the best thing to do is the DG snorkel. I don't have one yet, but the dyno tests of my Vforce show that the snorkel will make a significant difference. I'll try to get it on the dyno this week with the P700.[img]i/expressions/face-icon-small-cool.gif[/img]
