Me and Ed Kolano in the Sportster ! ! ! 

Below are some pictures of the exhaust pipes I just finished... 5-30-05.  I think they look real nice and will let you know how they fly.  

The old pipes were a 4 into 1 system where Cylinders 1 and 3 were piped around the front of the engine and joined with the Cylinders 2 -4 on the left side of the engine into one output.  Having 2 pipes real long and 2 real short is bad.  Also having 2 pipes travel all the way around the engine below the case is asking for a hot running engine - particularly on taxi when there is little airflow through the cowl.  Getting the carburetor heat air to the carburetor heat box was tough.  It was constantly wearing out the scat hose between the cowl and an exhaust pipe.  Maintenance to any cylinder required taking 2 intake tubes and all 2 exhaust attaches, a pain in the butt!

These new pipes are close to the same length but are 4 into 4 so I don't think it will matter as much anyway.  They go directly out of the engine.  They are ceramic coated to keep the heat in the pipe (they say).  Now any cylinder can be pulled without a ton of work.

3-4-07 Update.  Well I've flown these pipes for nearly two years but only about 150 hours.  They are doing great.  My oil temps are at around 170 on an 85F day here in Florida.  The ceramic finish is holding up well.  No cracks, no worries.  The exhaust sound I'm told is different (from local pilots) they say the plane sounds mean!  Inside I don't hear any difference from the 4 into 1 that I removed.
