Someone correct me if I'm wrong, but the 2 into 2 exhaust with the crossover inbetween them(which is supposed to equalize the 2 pipes and improve scavenging) should be as effective as 2 to 1 exhaust correct. The crossover inbetween the 2 pipes should work similar to a 2 into 1 exhaust system. V8 cars use crossovers too.

I have a 2007 FXDSE which is my eighth Harley and I did not know they had a SE air cleaner. If there is a more effecient air cleaner can anyone give me details, pricing, part no. and hp increase. Does it look the same and is there any information online? I am going with a Sert and Big Radius pipes, sticker tires, any other ideas for more performance? Any recomendations on tires I do not care about mileage only traction.

 

Look to your right and click on Doherty under the Featured Sponsors section and check out their PowerPacc Air Cleaner. From everything I’ve read it is the one to buy, check out the testimonials, there are some real substantial hp gains claimed there. The only thing I can tell you personally thus far is that it is a very well built piece, I’ve had one for a month but it is still sitting on the workbench due to the weather not cooperating and not allowing me to fetch my bike out of storage.
