00:00If you've ever had a gas engine go quiet on you at 200 feet, you already know the exhaust isn't
00:05the place to save a buck. A bad header, a cracked ring, or a pipe that won't hold a seal
00:10can cost
00:10you an airframe, and that's why I went hunting through the listings to find the best deals for
00:14the top 5 gas engine exhausts for RC planes. Some of these are full exhaust systems, and a couple
00:20are the small supporting parts that keep a gas setup reliable, so stick with me because number
00:25three is 13 bucks and it might save your plane. First up is the YAO Saito Ring Exhaust, and this
00:31is the big one at $607.57, with a 4.8 rating and almost 5,000 sold. What makes it
00:39worth the money
00:39is the ring row design built specifically around the Saito four-stroke family, so it fits the FA-120
00:44or 3, the FA-200 or 3, the FG-60 or 3, the FG-90 or 3, and even the
00:50FG-73 or 5 radial. You get a
00:53genuinely tuned, smooth mid-range instead of that harsh bark, and one exhaust covers half your
00:58hanger. If you're running a radial and want it to sound right, this is the buy. Then there's the
01:04aluminum prop spinner, and honestly at $7.08 with a 4.8 rating in roughly 4,700 sales, it's the
01:11cheapest
01:12insurance in this whole list. You're getting a lightweight, balanced cone in sizes from 32 all
01:17the way to 114 millimeters, so it fits everything from a small nitro plane to a big gasser.
01:23The balanced part matters more than people think, because an unbalanced spinner will shake your
01:28firewall loose over a season. $7 to kill a vibration problem, that's a no-brainer.
01:35Number 3 is the Resexel Opto Gas Engine Kill Switch, version 2.0, and this is my favorite value pick.
01:42$13.39, a 4.9 rating, and over 4,000 sold, and what it does is shut down your ignition
01:48cleanly from
01:49the transmitter with full optical isolation, so you're not feeding ignition noise back into your
01:53receiver. That means no more random glitches and, more importantly, a reliable way to kill
01:59a running engine if something goes wrong on the ground. For $13, everybody flying gas should have
02:05one of these. Number 4 is the other ring exhaust in the Saito family, the FA and FG series ring
02:11row pipe,
02:11and this one sits at $337.84 with a 4.8 rating and 3,600 buyers behind it. Same engine
02:19fitment as
02:20the flagship, so it covers the FA-120 or 3, FA-200 or 3, FG-60 or 3, FG-90
02:26or 3, and FG-73 or 5,
02:29but at roughly half the price of the first one. The build is clean, the welds hold, and it does
02:34exactly what a ring exhaust should, which is keep the noise reasonable and the back pressure where the
02:38engine wants it. If you want the performance without the premium, start here. And number 5 is the budget
02:45entry, the gas engine ring exhaust pipe for the same FA and FG lineup, coming in at $232.64 with
02:52a 4.7
02:53rating and just over 3,300 sold. This is the one I'd point a first-time gasser at, because you're
02:59getting the correct fitment in the ring designed for a fraction of the cost, and the rating tells you
03:03people aren't sending them back. It's not the fanciest finish, but it seals, it fits, and it
03:09gets your engine breathing properly. Spend the savings on fuel and go fly. So those are the 5,
03:16and honestly there's a price point here for every budget, from a $7 spinner up to a full radial exhaust
03:21system. All the links are in the description below with the current prices, so check them before you
