I have tested some different drag pipes and wanted to give an update on the outcome...

I have ran the duall drag pipes and did not see any power increase really at all.

I then put the ron wood pipe back on and it ran better..

MR Horsepower then sent me a custom experimental down pipe, I ran it and felt more HP and torque gains than I have ever felt with ANY mod I have ever done, No joke...For those who drag race, befor you go and get a big bore kit, or other expensive mods, I highly recomend you try Mr. hp custom pipe...you wont believe it until you ride your bike with it on...I still am scratching my head wondering how it works, but I think it almost vacumes out the exhaust..If anyone tries one please let me know your results..Thanks, Hope this info helps...I almost didnt want to tell anyone about the results due to more competition..LOL

 

Any pics?

That looks like an old megaphone pipe from the sixties.

 

a dual drag pipe setup should make more peak power in theory. who makes the dual drag pipe? is there a pic of the dual drag pipe?

 

I think my name is already on the list to receive one of these pipes. I can't wait to check it out!

Here are some pics of a drag pipe that I am working on for my Raptor if anyone is interested.

I dont have any pics of the duals...They are really straight head pipes that dump on each side under each foot peg, they are width of the RW head pipe with 2 mild bends( I dont think they flow like this down pipe)..I noticed such a bigger gain from this drag pipe that I have to gear completely different due to different torque range...It feels like I am running bigger cams also, I run smaller cams for the hill and It streched out my gears quit a bit and even helped up top, but I still need to go taller due to more bottom end, probably 17-35 w\hard 2nd gear launch.. Talk to Eric about the theory of his pipe, I think he designed it and adjusted it running on the dyno..I think. If I get the Pami cylinder and run a 108mm lightweight piston (stock stroke) It will really let the motor breath with the pipe..Scooby, If I can make it to Glamis in a few weeks I will let you ride the bike with both pipes so you can see what I am talking about.
