TRUE DUAL EXHAUST on a 4cyl? how it sounds, and how to do it.

[@hoost3056]

Old school four cylinder motorcycles with dual exhausts were set up like this.

[@quinnobi42]

my first thought when hearing it was that it sounded like a motorcycle.

[@vaughngordon1095]

Ford Ranger 2.3 liter engines always impressed me. They are durable reliable and full of surprises. Oddly enough, the nearly same 2.3 resides in some fox body mustangs and I found out how to get that lovely low end rumble of a v8 without the high end weed whacker fuzz. It was simple and a happy accident. I pulled the busted stock muffler and grabbed a length of 2 inch exhaust stock pipe and used the bender with the 2 and a half inch dies. Staying in plane, I put two bends to line up like the muffler and decided to use the pipe with its flattened out oval shaped turns. The result is that as the sound resonated through the oblong curves cancelling out certain frequencies which used disruptive harmonics to cancel out the "fart-pipe" noise.

I Was kind of agreeing with you on that. Kind of sounds like a detroit to me.

For it to sound like a V8 they would habe to custom make a crossplane crankshaft and change the firing order with a custom cam. And then they would end up with a great sounding engine which would absolutely shake itself to death while making less power.

Yep this is what I thought of as well! 8v Detroit

[@marv8481]

There are some confused people in this town still looking for a Subaru WRX lol (fyi, subis get their sound from an unequal length exhaust header leading to the turbo. Actually most v8s lope/burble is as pronounced as they are is because of the crossover pipe, making their exhaust headers essentially “unequal” as well. Yes, most v8s will have a lope without that but it’s more pronounced because of that)

[@direfox240]

Idea to quiet it down and get rid of the clapy sound. Non-true 4 into 4. Basically done the exact same way you have but instead of putting cyl.s 1 and 3 into one pipe, leave them in two pipes but use two X pipes(total four for whole system). Each X turns the positive pressure wave into two positive and two negative waves, the second X is important for using the negative waves as sound canceling. I've seen/heard some exhaust shops use this method instead of adding mufflers to some vehicles. Also have no idea what would happen if you Y'd each side down to one pipe after it goes through the double X. I for one would really like to see/hear you try it.

[@just2dudesinabasement464]

@@direfox240 I actually have done an x, and a y setup before. The only reason I don’t run them is as soon as you cross the two sound waves it kind of cancels out and sound like a regular 4 again. By a performance standpoint, yes it would be very helpful. I tried putting the crossover just before the exit to try and keep it separated longer, but when it’s that far back in the system it doesn’t really do much of anything. I think mostly for the “snappy” problem the best way would be some larger diameter pipe as all of them I’ve done are 2”. It’s just a little difficult to fit big pipe under small cars, with a muffler, and twice. Maybe some resonators, or just actually good engineered/ more expensive mufflers would do it.

[@MrMinuteman69]

I had put dual exhaust on a 1976 Subaru DL 1.4 liter, 4 speed manual trans, 4 door car I had. Original exhaust had rusted away. The engine has two exhaust ports one on each head. Boxer style engine. They originally had 1 1/4" pipe. I put 2" from engine to rear on both sides with a 24" glasspack on each. I was working at shop that did exhaust work. Tips turned down behind rear bumper. Reving it up would blow dust up. Sounded wicked as heck. Ugly little rust bucket of a car but sounded mean. Had several kids want to buy it. Car finally rusted so bad rear suspension started coming lose from body and I parked it. Some day I plan to use motor and trans to build a small buggy or cart.

[@sirjhonson8218]

[@spartanboss4189]

I’m excited to see that inline six setup, pairing 1-5, 3-6, 2-4 would probably sound similar to your 1-2, 3-4 setups on your trucks. Now If you did 1-2, 3-4 and 5-6 it’ll have a 120 (240* crank) degree firing ( except 3-4, those will have a 360*firing) and sound similar to a Harley coming out of each pipe. Or more like an Indian scout since those have 60 degree twins and have similar firing

[@spideronco86]

Outsides together and insides together gives you equal pulse distribution, which is the route to maximum scavenging. Many Toyotas use(d) a cast manifold that paired the outsides and the insides, then a steel dual downpipe that merged about 18 to 24 inches down.

[@Krankie_V]

[@garyuselman8597]

[@-CHEF-]

Before you unveiled the cavalier I just had a hunch that it was probably gonna be the cavalier after you said “both my cars have the same firing order and engine” there’s only one truck and car combo that comes to mind that basically share the same exact parts 😛😛 staring at the 96’ s-10 engine in my 02’ cavalier as I type this I passed right at 2:00 when i saw those darn headlights I just knew it!!! Gonna try this on my cavalier it has a custom ground cam in it let’s see how she eats!!

[@ItsDaJax]

I love it, sounds better than most performance header setups. I'm curious if there's a performance difference, or how it'd sound going into a single pipe.

[@bjsteg79]

On the 2jz would scavenging increase or decrease if you gave each pulse some time between firing? Meaning, instead of sequential firing order, go every-other cylinder so it would be 1-6, 5-2, 3-4. Performance aside, I'm more curious to see if the exhaust notes from the tri-pipe setup harmonize or clash. One of the headers is going to be considerably shorter and higher in pitch unless you make all the runners equal length. Lots to consider, this is fun!

[@steveengelbrecht7271]

Bet the neighbors are thrilled.

[@jacak47410]

dude. I wonder what a ford 300 would sound like with that setup. pretty good sounding engine.

[@twoeightythreez]

So, if you pair 1&3 and 2&4 , and then make the primarys unequal length, you will come very close to a crossplane sound (but at the expense of power---but who cares) 😊 A crossplane 4cyl would have a 1-4-3-2 firing order (with firing events at 90 and 270deg) which is a big part of the choppy sound, not the exhaust piping. A flatplane 4cyl has even firing events at 180deg. Thats why a Harley has that unique sound, a Japanese cruiser V twin is even-fire so doesn't have the potato-potato idle a harley does.

What if… If each exhaust port split into two separate runners for a total of 8 runners? Then you have 4 equal length runners, 2 shorter, and two longer runners. Would that achieve close to cross plane v8 sound?

Both header arrangements will give you the same 180 degree firing. If you want to try a different firing you can pair 2-3 and 1-4 for a 360 degree firing, and I highly recommend a glass pack on each side to take the edge off the sound
