exhaust system

[iwa]

has anyone used either a gasbox or a paughco stock exhaust system for a 52 panhead and which one would be recommended?

Iwa,

I've used them both numerous times on different bike build's.

I really dis-like an exhaust system that has any leaks in it. It bothers me a lot audibly and changes the fuel system calibration.

Quite a few times I've blended the Gas Box and Paughco systems together to get the fitment I'm after.
What I like about the Paughco is the one piece s pipe and y pipe. It eliminates one chance of a exhaust leak and gives more room to tuck it in tight without contacting the crankcase and brake bell crank.
It's not an entirely original design/look but functionality is more important to me as a rider.

If the bike was just a static display I would use the entire Gas Box OEM based design.

Hope this helps,

Gasbox has improved the fit over the year. Last one I bought fit without any alterations.
