My bike is stock and I was thinking on some mods. I have a dyno jet kit and a K&N Filter in the bike with a moded end cap. Which MBRP pipe to get. The race slip on or the regular slipon. I also have a ron woods cdi.
Will I see any horsepower gains over the endcap mod for my 300 bucks. How much have it pick up bikes. I can't find any number on power out put of the pipe. If I can't find any numbers I figure alba would be the next choice. Get a full system for the cost of a slip on

 

You may not see any power gain with the slip-on over your end cap. When you add cams and carb then the full system will give you more power.

 

we found our biggest gains around the gearing. we did real well that way we raced several others with pipes and not geared right, and would win by a lot. my thought was to get the power to the ground clutch springs and sprockets, then we got a full pipe hard to say what the length gains were with just the pipe.
