Looking for some cheap speed and it looks pretty good too. Have seaplane exhaust but is landplane.
1. Any measurable speed gain? 1kt would be worth it
2. Where's the best place to buy?
3. Any prep other than a rattlecan of matterhorn white?
4. Ease of installation?
5. Any cooling benefit?
6. Other pointers on it?

Here’s the one I know of, I don’t have any experience with it though. https://aircraftspeedmods.ca/products/e ... stc-sta-4/

I'm also interested in any PIREPS - I bought this as part of my new firewall forward (pponk, seaplanes west engine mount, acorn exhaust). I bought it because:

1) I like how it looks
2) For the purported effect on reducing engine temps

Anything else is just a happy added benefit.

I'm also interested, particularly if there's any difference in engine temps with one of these.

My exhaust fairing easily adds 15-20 knots TAS. Right. Minimal gain I’m sure but it does look ok. Haven’t flown without so don’t know about the temps. Must be removed to get lower cowling off but nice machine screws attach it. I’ll try to find STC paper on it for more information.

Yep, Maple leaf, thanks Limerick!

I installed the Maple Leaf exhaust fairing on my C180K approximately 7 years ago to reduce CHT's as I did not want to install the shark fins. SoCal and Arizona flying temps. The fairing took approximately 10-15 degrees off the CHT's. YMMV. No speed increase as far as I could tell. I slip a heavy sock on the exhaust when removing the cowl to not scratch the paint. Easy cowl removal and it was simple to install. I drilled out a few rivets (heads were in the way) to get a nice flush fit. Prior to final install, I used a small airbrush to primer and shot Vestal white JetGlo to match. Highly recommend. Looks good too!

Please note: the fairing does not need to be removed prior to the lower cowl removal. Cowl slides out easily from the exhaust pipe. Cheers!

My sister-in-law has a full Maple Leaf kit on her Cardinal. We’ve been doing some things and talked to the Maple Leaf guys a few times. It appears their stuff does what they claim. Limerick’s pirep on the actual product being asked about seems to agree. Hard to go with a $300 airplane mod...

I’d like this mod, but I’m adverse to plastic on my 185.

Other issue is I bet it only fits the right hand side. I’ll soon have the Leading Edge Exhaust by Powerflow, with dual exhaust and would want a fairing for each side.

I hope two exhaust openings aren’t going to cause me a cooling problem.

Sam here, I just purchased one from maple leaf but have yet to get it installed.

I installed this fairing many years ago primarily to reduce stress on the muffler after I installed a slip -on exhaust pipe extension from Kenmore. The Kenmore extension eliminates most of the soot stains. The cowling is easily removed and installed with the fairing in place. I've never had a problem with high CHT so I didn't notice any change. Speed gain - I gave up that quest a long time ago - it's a Skywagon.

Very nice photo in any case....

I like this one better than maple leaf, just from a looks perspective. It does help with CHTs a bit. I don't know of any approval to install it though.

Much better

Don't see that product on their website.

They sold one to me about 6 years ago, STC SA10351SC, Texas Skyways Drawing TSFG-100-1.

Hard to say in my installation if it helped CHT as I replaced the engine, baffles, and baffle seals at the same time I installed the fairing. Highest CHT I've ever seen on my machine was around 390f.


Since this photo was taken I’ve switched to Acorn Welding/Seaplanes West muffler, no problem slipping cowling off with that setup.

I have the same set up. Did you install two Pinecone?
Thx

I installed the maple leaf fairing on my 175, which has very high chts on one cylinder, No change I could detect. Speed? Not that I can tell.
They were quite candid with me about potential benefits....said it depends. I wouldn't do it again, certainly not just for looks.

I still have the exhaust system here in the box it arrived in. I was flying regularly until it got really cold and didn’t want to take the airplane out of service. Now it’s been cold or I’ve been busy. Hangar is not heated. I haven’t considered the fairings any further. Can you get them as a pair now?

Installed the maple leaf. It looks nice. I didn’t have great winter baseline temps but before I couldn’t get away with fully closing cowl flaps now I can. So it’s a speed mod in so far as you can do that. Estimating 10 degrees on cylinder 4. Would recommend as long as it doesn’t crack up.
