Exhaust System

[Mark Anderson]

Any recommendations for a replacement exhaust system for a PA-24-250 that is an improvement over the stock system? Mainly less heat on the firewall?

Thanks,

Mark

Hi Mark,

The only aftermarket one that I am aware of is from APP who advertises in the flyer. For a # of reasons I think it is a good product and the products they sell have a good rep. It does appear that some people have found them to be hard to deal with but I base this solely on past forum comments. I have no personal experience.

The APP product essentially duplicates the 260 twin exhaust. That is what I have and if you fly in a warm area you will appreciate how much cooler the cockpit is after you move the exhaust away from the firewall.

Good luck, Don

Thanks Don, does it make the engine any louder?

Hi Mark,

I really can't answer that question as I never had the earlier system on my aircraft and don't have enough time in a 250 to make a comparison. I like the Harleyesque sound of the dual exhaust and don't find it too loud in the cabin although admittedly I have always used headsets. I imagine there would be a slight increase in performance due to less back pressure.

Hi Mark,
Just finished installing the dual exhaust in our 61 carbureted 250. Dave's product quality is outstanding. It's a much better system,utilizing slip joints, and stainless steel tubing. Dave support is great. He just gave me his cell number and always picked up with my many numerous questions during the install. I am very happy with the result. It also eliminates the recurrent muffler inspection AD.
Is it any louder? I would say no louder, but different. More throaty perhaps. Admiringly I have only been able to take a few test flights with the new system, and that was with the interior completely removed. Right after the install it went in for some avionics work.
The installation is not too difficult. I am a do it yourselfer , and with the help of my IA got it done. It took me about 40 hours for the install, but I addressed other issues while it was disassembled , ie oil return lines, intake gaskets, chaffing prevention, etc.
It definitely will help get rid of all that heat on the firewall. That was my main reason for the switch.

Good luck
Andrew

If you need exhaust work on your current system, do not pass go, and do not collect 200 dollars, call Dave and order a set of duals. You will be VERY glad you did. The engine breaths better, its cooler in the summer, the heat works better in the winter, your steering rod boots will last forever, you will not get vapor lock on the ground, and your mag condensors will last indefinitly without all the extra radiant heat of that stupid stock transverse muffler. If this sounds like an glowing endorsement of the product, it is. Not only are they excellent quality, but the investment made today will pay dividends in all the other areas mentioned down the road.
