First off, Fred gets this stuff to you *quickly*. He shipped it
Saturday, I had it Monday.
I went into this armed with info from this group on the various
exhausts. I knew I wanted something that gave me more performance,
and one I didn't have to repack. So to me the obvious choice was the

gathered up the materials he recommended and set to it.
The installation is very straight forward and I used the extra parts
John suggested, they came in handy. After a painless install I fired
the A15 up and liked the sound. Better than the stock, could be a
little throatier for my tastes, but definitely a deeper tone.
The test ride revealed quicker throttle response, and you can tell
the engine is breathing easier. The sound you get from this exhaust
up around 5~6K rpm is very satisfying. I got no backfires going

I installed the K&N filter and jet kit last weekend and everything

observation about what would be better - it would have been nice to
have a heat shield where the stock one had it to protect a passengers
leg getting on and off the bike. But then again, I'm not the
