Sutton Exhaust on a Pacer
I talked to Brian Sutton with Professional Pilots, Inc about his exhaust system for the Super Cub. He has had several people get field approvals to install it on Pacers and he sent me a copy of the Super Cub STC paperwork and copies of these field approvals. Rex is going to see about getting a field approval for the exhaust system on his Pacer. The system is basically a Grumman Tiger exhaust, mounting the muffler in front of the oil sump instead of against the firewall. It requires a hole in the bottom cowl for the tail pipe. Brian designed this system to allow for the rear mounted prop governor on his STC for a constant speed prop on the Super Cub. He said he will pursue an STC for the Pacer and Tri-Pacer but needs time and a donor Tri-Pacer to work out the clearance issues for the nose gear. This will probably take some time but will be in the works. Nice to know there could be another exhaust option without the muffler AD.

Re: Sutton Exhaust on a Pacer
Is there really room for this system on a T-Pacer and the nose wheel?
It would be great to have another choice which is also lighter.
Re: Sutton Exhaust on a Pacer
I have several pictures from another short winger who had his field approved. The STC includes going to a more modern oil cooler and moving it behind the #4 cylinder. You end up building a new lower cowl but you get a real clean install.

Rex, Get Kim to post those pictures. ;)
Re: Sutton Exhaust on a Pacer
Put the Sutton system on my Pacer last year. It is a very clean installation. It is superior to original in every way BUT you do have to get used to the stack sticking out the front part of the cowl.

Re: Sutton Exhaust on a Pacer
Paul, Nice installation. Did you notice any difference in the round air filter or have you ever compared it with a square?
Re: Sutton Exhaust on a Pacer
Sorry. No point of reference there. The round airbox is all I know on this engine. My bottom cowl is fairly beat and when/if I ever install a new one, I've thought about going to a square box.
I do have paperwork on that installation if anyone needs it pending the Suttons getting their STC ammended.

Re: Sutton Exhaust on a Pacer
I will see if I can get more pictures posted.
Re: Sutton Exhaust on a Pacer
Thanks for starting this thread Steve.
I also got Brian's paperwork and have been picking away at a field approval. My FSDO(or perhaps just my inspector...) is very particular about 337s these days and I'm afraid the previously approved ones Brian gave me won't be much good. Anybody else out there with picky FSDOs having any luck with stuff like this?

Re: Sutton Exhaust on a Pacer
Does anyone know what the rationale is for not simply mounting the oil cooler directly to the rear of the engine baffel?
