I need to order the ss for the exhaust.  Tracys' manual calls for 1-3/4"
size, is this connected to the flange by a cone shape or have you used a
hole smaller than the exhaust ports in the engine.  Awhile back someone
posted a picture of some enserts for the pipes, has anyone found some that
havn't burned out shortly.  Would the exhaust pipes need to be 2" at the
outlet so inserts could be installed.  The 13B is installed in a Tailwind
W-10 w/ tri-gear and I don't have any room for a muffler under the cowl.
Thanks for any and all input.  JohnD in Michigan
