I just had this idea and wanted to know what you guys think.

On a v6 or v10, what would happen if you ran dual exhaust with mufflers, but cut the manifold from 1 cylinder on each side and bypassed the mufflers ?

Would you not get a v-twin type exhaust sound?

 

Um... what about emissions ? And the fact that the O2 sensor isn't going to "see" that cylinder firing anymore?

 

I was thinking of use on a tuned truck

 

It sure wouldn't sound like a v-twin as the cylinders aren't firing at the same time like the do on a Harley for example.

 

If you looked at the firing order, why could you not pick 2 cylinders with the right timing gap?

 

My father in law has a chev 4.3 gas motor, the rear cylinders fire 1 after another.

 

He wants to make is truck sound like a Harley-Davidson! What's the point? Just get a Harley. An Electra Glide weighs about as much as my F250, and by the looks of the women passengers I see on most HDs, the bikes must have the same load capacity as my truck.

 

That there's funny! I don't care who ya are!

Red neck-ish maybe, lol.

Anything remotely close to a harley would be 100x better than the exhaust sound from a v6 or v10.

 

Step 1, remove said v6-v10, Step 2, toss in the pile of scrap , Step 3, install 7.3L psd. Remove exhaust,intake and foil. Enjoy

 

How bought a loudspeaker and a tape of a 7.3 at 30 psi of boost?

A Harley doesn't fire both cylinders at the same time, does it? The cylinders share a crank pin?

You need to stop now...

 

I swear Art it was Monty! I left the IPAD in front of his food dish for 5min. and look what he does! Good Dog!

Yes the cylinders share a crank pin. And yes they do fire at the same time only there is a wasted spark. Ignition only happens on a compression stroke.

To the OP i love my Harley but i wouldn't want my SD to sound like my HD.

 

in theory, it would be possible to do to any engine.
take two cylinders that fire 270 degrees apart, and route them to a separate exhaust system, then run that straight out, while putting the other cylinders through a full muffler system.
the problem is that a vtwin sounds lumpy because there is not much momentum built up in the engine at idle, so the speed and timing are erratic.
the large heavy flywheel of a v6-8-or 10 cylinder engine will simply give you an even sounding two pulse drone, nothing at all like a vtwin
