Re: KR> 4-into-1 exhaust system help?
When it was time for my exhaust on the KR I Talked to a local muffler shop and then loaded it up on a trailer and took it to them. He said he would be glade to do it because it was something different. It only cost me $350 and everything fit. It was not stainless and I did have it wrapped and it lasted quit a long time.

Re: KR> 4-into-1 exhaust system help?
Mark I feel your pain.Last years inspection revealed similar issues related to rust[mild steel].Only one pipe was rusted thru but we know what that means.Revmaster will make me another one in 30 days for $510 and I would do that in a heartbeat If it weren't for retirement.I bowed up and used some mandral bent pieces left over from an intake project.Welded up the offending pipe and I'm in the air again.I have not seen anything but the 4-1 with offset offered in quite a while.GPAS and Revmaster may get theirs the same place.The area around the collector was a challenge but doable.Repair will get you flying and buy some time for better fix.Tommy W.

Re: KR> 4-into-1 exhaust system help?
Chris Gardiner wrote: The only difficulty I had with the Revmaster is that it is slightly different at the back and interfered with my intake manifold ( Zenith 1821 carb.) Is your intake a Great Plains that angles back toward the center for a few inches on top and then goes straight down on each side, then a 90 turn in to meet in the middle? If so, that's what I also have. There's another incarnation of the GP intake that stays further outside. If it's not a hassle, a photo of exhaust and intake would be helpful, if you happen to go to the airport. I've looked at the Revmaster exhaust and it looks less compact in several ways, but maybe it's just an optical illusion. The photos at http://revmasteraviation.com/?p=183#more-183 also shows the same thing I see on John's exhaust, that the collector and exhaust pipe point down at a steep angle and extend a lot further down than my current exhaust. I'm afraid I'd loose 10 mph with that exhaust, and would certainly have to do major surgery on the cowling, on the bottom and maybe at the exhaust ports, as the radius on the ports looks larger too. A measurement from the bottom of the engine vertically to the bottom of the collector would be a good data point for me. I could re-angle the exhaust to make it more in line with the airflow, which is how the current one is. N56ML's exhaust is maybe an inch from the bottom of the plane, but I put a thin stainless sheet and fiberfrax behind it to withstand the heat. The stainless steel is a no-brainer, and this is probably the way to go in the end, if it'll clear all the crap on the firewall without a major under-cowling redo. Thanks to all that replied...

Re: KR> 4-into-1 exhaust system help?
Mark, I can send you some dimensions on the GP 4 into 1 pipe as I have one. The pictures John Bouyea posted show the offset from the front view as well as anything I can send. Suggest you consider the Revmaster stainless 4 into 1 option. I installed it last year for peace of mind that it will never rust out . It has about the same amount of offset. I will take a picture of the SS style and measure it today for you. The only difficulty I had with the Revmaster is that it is slightly different at the back and interfered with my intake manifold ( Zenith 1821 carb.) This may not be an issue for your set up.

Re: KR> 4-into-1 exhaust system help?
Mark, Here's what I can share right off. If the Quickie exhaust system would work for you, lemme know. http://www.bouyea.net/cur_proj/n5391m/exhaust/Default.htm I also have another 4-into-1 for a TriGear but no photos of it tonight but I can have some for you tomorrow.

Mark Do you necessarily need a 4 into1?

KRnetHeads, My VW exhaust system broke while flying last weekend, and given the location and pervasive nature of the welds required, it's not repairable. GPASC has no KR exhaust systems in stock, but they can make one for me in 30 days. They also no longer sell the 4-into-1 "centered" system, offering only a "KR Tri-gear" model that has the outlet biased towards the pilot's side. This would be fine if it didn't interfere with something else, but I don't know exactly what it looks like, and I don't think GPASC does either. One choice is to build my own, but it would be a lot more expedient to buy the Tri-gear if it'll fit without having to modify a bunch of stuff. That's a big question, because I have a fuel rail with gascolator, totalizer, and pressure sender down low on the firewall, and would rather not have to conjure up a place to put them all, because that's about the only place they would fit. So I'm wondering if somebody with the GPASC (or other) 4 into 1 Tri-Gear exhaust system can lead me to a few photos and maybe some dimensions of their exhaust system and surroundings? My current system has the four equal-length pipes all bending in parallel to the collector in about the same plane as the rear exhaust flanges, if that helps. Another option is anything else that looks like it might work.

Re: KR> 4-into-1 exhaust system help?
I know this is not what you want to hear but if you can not find an exhaust "fiber fix" will help seal it until someone can build you what your looking for. It is water activated epoxy impregnated carbon. I have used it in a jam and it's still holding up to everyday abuse on a Detroit diesel exhaust in my work boat. Just a thought.
