Cone Engineering for Exhaust Components

[Longitudinal]

When I built the exhaust for my GS1100GL, I bought all of the materials (tubes, collector, collector bullet, bends, muffler) from Cone Engineering. Price was very reasonable and quality was excellent. I highly recommend them and will definitely buy my exhaust parts from them in the future.

They have some cool kits for Harleys. Unfortunately, they don't flow as well as a few other assembled exhausts (at least on HD).

That's a surprise. It must come down to tubing sizes, because their collectors are the nicest formed collectors I have seen.

One thing I absolutely have to give to the HD community is its obsession with dyno tests. There is a very reputable HD tuning shop that has exhaustively tested pretty much every HD exhaust out there. The manufacturers send them pipes in advance because they know people will want their opinions. It's not just tubing sizes (that would have been fixed), it's reversion due to shapes and lengths.
