Go for the LRD. Get it chrome and it will run right at $360. Don't know any certain hp gains. But i know i can smoke other piped, jetted, and filtered ex's and mine is all stock except for pipe. I beat others from top to bottom and gained about 8 mph on top end.

 

did you jet yours if not you are probably running a little lean. this makes them run better but is hard on the engine

 

What other pipes did you go against?

 

I haven't jetted yet. Thats my winter project. I have beat ex's and 350x's that have DG, Haveen(i think thats it, it's the ones that come from honda dealer) White bros, Cobra, and big gun. If you want to spend a little more money I would prolly go with the Duncan double barrel. But i love my LRD
