David, if I remember correctly you have the James cowl correct? If so make sure that Clint added the extra twist to the forward cylinder down pipes so that it clears your cowling. I had to send both of mine back to get this adjusted. He may have already incorporated that into the design now but thats the only place I had any issues that I recall.

Thanks Darin! I did look at your build site already. The pics were helpful.

Hi there, check that the flanges mate up to your cylinder exhaust port surface squarely. Mine did not, I had to file one side down to make them mount properly. Apparently the centre to centre distance on my engine was different than the fixture used to make them.

The up side is that I now have 290 hours on them, without any issues.

Wish I had known about the adjustment for the Sam James cowl, I fibreglassed a bump out to clear the left side.

Use mouse milk on all the slip joints before installation, and whenever you have the cowlings off.

Well I got the exhaust on last night and it seems that the forward ends of both heat muffs are contacting the cowl. I'll play around with it some more today then probably have to call Vettermans. It did go on easily though and was fun messing with something other than the canopy and cowling. Really growing tired of those 2 freaking things!

Default Trombone on 8A

Has anyone done the trombone exhaust on an 8A. The Vetterman website says not sure at this time for 8A.

I installed trombones (without mufflers) on my 8A - fit without any issues. However, be aware that trombones will not fit the M1B engine with stock sump.
