True Dual Exhaust on a 4 Cylinder - What Will it Sound Like?

Here's what I believe to be the first true dual exhaust video on KZbin. I put a true dual exhaust system on my 2002 Nissan Sentra SE-R Spec V to hear what it sounds like.

Subject to correction but exhausts work on pulse and you got to match the corresponding cylinders together for a balanced motor...if not you could end up with blow back into the cylinders which kills power of the engine...i think its mostly 1st with 4th and 2nd with 3rd banked together...depends how your engine is timed

[@HatersGarage]

I think the true dual setup out Subaru's the Subaru UEL sound.

[@GTRFREAK17]

@@HatersGarage Definitily, gives it a sound closer to a 270 degree twin cylinder motorcycle

[@identiticrisis]

If you just picked up the merged pipes off the stock manifold, you likely have 360° firing pairs in each pipe. It sounds a little lumpier because they're unequal length between the individual cylinders, and the spacing between the outlets doesn't even those out at all (like an x-pipe would...) The 360 pairing is like Honda's F2 engines from the 1960s and the S800 racer, both had "true dual" exhausts and clips can be found on KZbin. Pairing the cylinders differently at the manifold / head would yield something closer to a boxer 4 sound, or indeed Honda 4 cylinder motorcyles of the '60s and '70s :)

[@joshboyer8449]

I did this to my 4cylinder, with equal length runner and a center collector for each running side by side and the splitting at the end sounds really good, Borla exhaust for the win

[@bellsouth70]

Sweet! I've been toying this idea in my head for a long time. When making a "true dual" manifold for a single bank engine did you have any troubles with the upstream oxygen sensor properly reading the engine? With a 4-1 or 4-2-1 manifold the o2 is in the collector reading all of the cylinders exhaust and reading it but in a "true dual" setup you'd only be able to read 2 cylinders with the o2 (unless wiring up another o2 for the other 2 cylinders although I'm not sure if that's possible without stock ECU without mixing up the readings). I know like me this was more of letting the intrusive thoughts win type of deal haha but do you know which cylinders are preferred to have the o2s read or it doesn't really matter? I want to do this to my 4 cylinder but I wanted to research exhaust scavenging to get the best performance out of it when making the exhaust runners and take it a step further by creating 2 manifolds to see the differences in sound and power if any. My engine firing order is 1-3-4-2 so I wanted to make one manifold have 1-3 on one side and 4-2 be connected on the other so its two pulses on one exhaust pipe before switching then the other manifold could be 1-4 3-2 so there's one pulse on one pipe then goes to the other pipe one pulse and then goes back etc. Just trying to help make some sound that isn't a fart can :)

[@HatersGarage]

The o2 sensor on my headers was already sort of only on two cylinders to begin with. It's up way before the 2-1 collector and could only really read two cylinders anyway. The car runs fine, and there's no check engine light to do with an o2 sensor. My firing order is also 1-3-4-2, and my cylinders are split 1-2, 3-4. Having headers setup to have 1-3 and 4-2 paired would probably sound more "normal". As for flow unfortunately a dual exhaust is just never going to flow as well as a 4-2-1 setup will. An x-pipe may help flow, but will mostly remove the "choppy" sound as well as increase pitch. If you were to install headers with a 1-4, 2,3 split with an x pipe, I'm guessing it would sound like a regular single exhaust.

[@nobodynoone2500]

You can usually just do any of the primaries and its fine, some hondas already used 2 upstream o2 sensors for tuning as early as 1987 on the JDM b16a.

[@wallsmr1840961]

The slightly clappy sound could be alleviated by like magnaflows maybe and a resonated tip and x pipe. It helped my m45 which is a v8 nissan basically and them and titans have that cis/ clappy sound and doing what u mentioned above made my car sound great 😊

I really like the rumbling sound of true dual, it reminds me of the V8ish sound you get on old Inline 6s with true dual headers, with X and H pipe this just goes ricey. I'm tempted to have an exhaust like that but on flat plane 4 cylinders firing in pairs there would be a huge mess with the flow so it's going to lose performance for sure, there just isn't anything to pull a vacuum after each pair fires like in a single exhaust which has excellent flow due to each pair's exhaust pulling the other pair's out, not that the pulse from its own exhaust doesn't do it, it just doesn't do it as effectively.

@@HatersGarage how did you split your header? Believe it or not, a couple months ago i had the exact same idea, did the same research, found nothing but that exact same forum, and decided to do it to my honda accord. Did the exhaust about a month ago. (Low key pissed that i found this video cause i wanted to be the first to document it but you made a more interesting video than i did so i give you props (as long as you didnt secretly see my video and steal my idea 🤔) I already had a header that was 4-2-1 that i used. Though this header paired cylinder 1-4 and cylinder 2-3. And with that split, each pipe has an even firing split (firing order 1-3-4-2). And i wanted an odd firing split so i cut and reconfigured my header to pair 1-3 and 2-4 for an odd firing split. Guessing based off the sound, that you paired yours 1-2 and 3-4 which also would be an odd firing split. Thus, your car sounds EXACTLY like my accord. However, i think if i had not modified the header and had the even firing split, i dont think it would have the same deep sound. The odd firing split adds a fundamental frequency 2 octaves below the normal 4 cyl firing frequency, but the even firing split would theoretically only be 1 octave below, and would have a totally different sound. But i dont think it would be as cool.

Incredible sound

[@saltysavage3756]

That's music to my ears! It kinda reminds me of a 4-banger demolition derby car.

[@Audi8pOfSouthAfrica]

Definitely difference in that. Cool video, thanks 👍🏼

Some motorcycles already do this, and you can split a 4 cylinder exhaust system in two, and have them each go out the left and right side, so your ears on the bike hear different firing orders, Stereo sound. A great motorcycle channel, RacerTV, made a video about choosing an engine for your Cafe-Racer project. Splitting the exhaust is one of the tips he gave, for tuning your sound to your preference.

Had a pinto. 2.3 was balanced and blueprinted with 2 2-bbl progressive carbs. Homemade headers ending with glass packd mufflers. 40 mpg, and sounded like a harley.

That actually sounds really good

I'm actually hyped on this. Id love to hear that similar sound and say another wrx then see a honda or Nissan

[@NewHamburgShenanigans]

Sounds awesome!

Sounds amazing! 😀

I did it on a 91 Nissan 240sx with a 97 kade swap. Had a 4 to 2 to one header...I just cut it where it went 2 to 1 and ran 2 2.5 inch pipes side by side to the rear. Definitely sounded unique. The idea came from my dad who did it to his sisters hornet mack in the day.

Some 30 + years ago my friends and I raced a German Ford Capri with the 2.0L OHC 4 cylinder. It had a header but then right after the collector we added a "Y" pipe that split the exhaust flow into two. Since the car was RWD we ran one pipe to the other side of the car so it was a full dual exhaust just that it started out as one pipe. We liked the sound as it was different from your normal 4 cylinder. We had people come up to us and ask if we had a V8 in it. Not sure if was because of how fast it was or how the exhaust sound. Just saying we found out you can change the "4 cylinder" sound, just in a different way.

Nice job, I like it.

[@shortarms4114]

Sounds really,really good.

The Boosted Boiz did it with a twin turbo K24 put into a MR2. It was a shorter dual system and it was twin turbo so the sound was much different. It probably doesn't really count as to what you're talking about but its the only exhaust anywhere near what you were asking about. They do have a big youtube channel. This was about Two or three years ago. I hope rhis helps.
