I really liked the auger inserts. They hardly weigh anything and you can't even see them when installed so it gives you that open exhaust look, but still has the noise reduction needed to not get hassled by Johnny Law.
I put the augers in the 3 inch exhaust on my 440 powered 53 Chrysler and am really pleased with the results both at idle and under throttle. Not only are they way quitter but at idle they have a nice deep rumble sound. Also got rid of the drone at 40 45 mph. We welded a 3/4 inch nut on the back of mine and you can then just screw them in or remove them if you want. These are hard to beat for the money and sound.. Sent from my iPad using H.A.M.B.
Hello, A long time ago, we teenagers used to try and keep any straight pipe exhaust noise down to appease our folks, neighbors and the CHP. Many items were used and as we can see, they improved the technology without hindering performance too much. The simplest method was to make the even flowing individual headers and then add in some inside fitting baffles. Ones with holes, slits and angular tabs. The designs were to muffle the straight through exhaust. Because of the exposure in design, mufflers were not going to happen on the lightweight T-Bucket roadster. So, those baffles did the trick, despite using a lot of them. The tone was altered to be CHP approved and after riding in the T-Bucket, it sounded very good to my ears. But, the whooshing wind passing by my ears also helped muffle the sound. Jnaki The Ford motor had an even number of exhaust outlets, making the symmetrical bends and curves very smooth and uniform. Cool looks plus the great sound makes this street roadster stand out from the rest.
The third ones are the ones like the Termi's on a Ducati. Here is a pic of a modified termi. You could leave the end open on the ones you buy and just wrap some fiberglass around the part that goes to the end. That could absorb some of the sound and you could tune it a little.
I can't tell you how nice it is having a car that doesn't blow me out with noise. I wasn't always like that, and wanted the pipes to be as loud as possible. Now I'd much rather enjoy my stereo and conversation with whatever passengers I have with me.
You don't have to tell us, we already know. If that's the experience we wanted we'd drive the daily driver. IMO there is something to appreciate in not having the stereo going or having a lot of discussion during a long drive, you settle in to the sound(s) of the car, the wind, the road, the smells, the changes in temperature. You aren't distracted by the music, or the talking, the news, arguments on talk radio, etc. You notice everything going on about you more, you contemplate things that have been on your mind. You want to talk to your passenger you lean over and talk, then you settle back into your seat for more. Maybe it comes from putting so many miles on 2-wheels. It's a nice way to travel IMO. Though I will admit it's more tiring, or fatiguing. If you really want to put in a lot of miles in a day, or a series of days, when the trip is all about the destination, than the daily driver is the way to go. When the voyage is as much the travel as it is the destination, then I'll take the exhaust & wind noise and do without the radio. Different strokes for different folks....
I can barely hear the noise from the pipes over my tinatus LOL seriously though what happened , loud pipes just got very tiring , Ive tried a few options without any great success , what I do like though is the chicken wire baffle .. so much so im going to be trying that later tonight ..
Check out these guys. They have been around a long time and have multiple noise solutions. I have bought many products from them and have always been pleased. https://www.carchemistry.com/ Warren
This is what me and dad came up with and it works surprisingly well, no need for earplugs anymore and I can still make it even quieter if I wanted by wrapping it in the muffler packing stuff. Eventually we'll weld it all up so I don't need the bars on the end.
I tried the chicken wire, first scrunched up and packed in , still a bit over loud . so turned out that I was at the end of the roll which just happened to be the same diameter as the inside of the header. so slid in around 18 inches, fired it up, nope still to loud . I had a couple of smithys so cut them open , surprisingly little inside them. Shortened the baffle tube bu a couple of inches , wrapped the fibreglass sound deadener tightly around the baffle and slid it in .. lovely tone at idle and not as head battringly loud as previous when revved but saps the power from the engine .. ( well what power a stock flathead can produce ) Gonna see if it can be tuned a little by fitting the wadding loosley as it was in the smithy .. next will be the washers up the baffle as above post .. Got a long trip with the car comming off and taking the wife , would be good to arrive without a headache
