Hey Everybody,
Just Got this installed by Tim's Air.This is a modified field approval of the Maule system to be STC'd soon. Even Jeremy came by to check it out and he gave it the big thumbs up!

In regards to the clamps around the heat shields-why the starboard side towards the center and the port side on the ends?

Hi Gary,
After talking to Jeremy & Tim they recommended moving the hose clamps toward the center because they could vibrate off the shroud. I haven't had them fall off yet but since I did notice without screws the heat shrouds did move off center. With screws the shifting off center is not a concern. I still have a concern about the screws in the corners of the heat shroud because that is where the fatigue cracks were exhibited on the old shroud. I personally don't think the corner screws are necessary and I may take them out. The entire effort from my point of view is to make the System / Shrouds endure as long as possible and eliminate any concern over Carbon Monoxide or damage to the aircraft. Although others on this site do have the hose clamps on the ends of the muffler but without the corner screws.

Suggest that you make sure to support the tailpipe in a manner that it can't twist as I put this system on mine about a year ago, first long trip the tailpipe twisted at bend area allowing contact with the cowl and burnt about a 2" hole in it.... The original mount at bottom of tailpipe and vibration encourages this situation and the old system has the tailpipes pinned at the muffler so that this can't happen. This new system does seem to illiminate the cracking tendencies though...

Thanks Jim as a matter of fact I am on my way to the airport to get that very thing done with tight clamps so no twisting hopefully
Not to get too far into the where and when on this, but I know I have happily been running one of Tim's improved muffler systems since May 2006 on my M5-235C
I think mine is Rev. 1.1 or 1.2 and there have been a number of improvements since.
W&B essentially did not change. I may have gained a pound.

Tim is great the system he is working on works well hope someday it will get certified...
New to the forum. I maintain a 1997 Maule MXT-7-180A since 1997 have had several instances where the aircraft has flown a max of 50 hrs. and a min of 17 hrs. and each time the exhaust has cracked. Cracks were found at the headers where the tailpipe meets the muffler and the actual tailpipe has cracked, all from vibration. Interested in info on a fix, recently heard about the ball joint placed in the system. Appreciate any input. Understand there has been field approval and possible STC for the 6 cylinder. Anyone gotten approval or STC for the 4 cylinder?
PM Tim, He has a user name of TimB on this site, you can look him up in the memberlist. Tim maintains a lot of Maules and has been improving upon the exhaust systems for quite some time now.
I had this done about two years ago but only the ball part that goes into the muffler and it was done on the left muffler... the rest of the system was ok....
