power cones

i scheduled my dyno tune for april 7th. the shop asked me if i had powercones in the exhaust. i don't. he said he highly recommends them and it makes a big difference. anybody agree/disagree?

i have them in my 98 dyna, carbureated. didn't really notice a difference.

i haven't heard anyone on this forum talk about powercones. was this just a sales pitch? he quoted them at 50 bucks for the pair.

RE: power cones

IMO, they go in the wrong end of the pipe to do any good. People wouldn't use the thinner SE exhaust gaskets if stopping up the exhaust port was good for peformance.

RE: power cones

the shop's quote was "they don't do much for back pressure but they won't let any exhaust gases back into the head".

i thought that's what valves were for...

I have power cones in my Samson II, Rip Saws. The Rip Saws come without baffles. The bike runs real good. I don't know how much if anything that the power cones contribute.

RE: power cones

you will be pleased....they stop reversion...something i wont explain cause most have no idea what it is or what it does...they do however give you a seat of the pants feel in the lower rpm range
