Exhaust system delete?

[Sheepdog]

I'm noticing that there is a clamped slip joint in the exhaust system just ahead of the muffler, which also happens to be pretty near the back of the cab.

I've seen all sorts of muffler deletes, but has anybody tried just deleting the entire remainder of the exhaust system at that joint and replacing it with a simple turn-down?

Turbo engines are not nearly as loud as comparable non-turbo engines, especially when exhaling through the kittys...

You guys should just swap each other out.

I don't know if I'm willing to give ours up, but thank you.

Trust me it would be loud and sound like trash. But some people love the sound of trash

I removed my muffler and put a straight pipe in, keeping the rest of the stock exhaust.

I hated it, my wife hated it.

I ended up putting a muffler back in because it droned so bad and just plain sounded awful.

I don't think I would like a turn down there at all, but YMMV.

You know what they say!
One man's trash is another mans..........kid driving down my street at 3:17 AM with a loud ass fart-can muffler and a stereo that rattles my fillings.

I can't imagine the girls that swoon for this chap.

I'm more interested in the potential of losing some weight, for free.

I've got other irons in the fire right now, but I may pop it off at some point and see if we can live without it. If we don't like it, maybe a race bullet muffler on the end of the pipe may calm it down. The Ranger is not gonna be a daily driven vehicle anyway...

It's been a very long time since I have messed with exhaust systems on cars or trucks.

I know on motorcycles you have to have some type of muffler to maintain back pressure for proper performance. On such short exhaust systems found on motorcycles, maintaining back pressure is a must so that you do not burn up valves.

Those with more experience can give more information on how much back pressure you need to maintain with the 2.3L Ecoboost motor.

I personally would not run any type of motor without some type of muffler to maintain some back pressure on the system.

Back pressure isn’t as much of a concern on a turbo motor.

That's an old wive's tale. I have successfully built and raced cars and motorcycles in numerous motorsport disciplines. All engines perform best with no backpressure, ESPECIALLY turbo engines. The turbocharger's turbine wheel already adds back pressure- you don't need any more.

I suspect that particular old wive's tale comes from people removing restrictions from the exhaust systems of stock vehicles, which increased the engine's VE (Volumetric Efficiency), allowing it to move more air, but they failed to add more fuel to that larger amount of air, which results in AFR (Air-Fuel Ratio) going way above stoichiometric, to the point that EGTs (Exhaust Gas Temperatures) went sky-high, torching pistons, spark plug electrodes...and exhaust valves...

I agree back pressure don’t matter. Chop the exhaust an inch after the turbo and let her rip tater chip

This is an RCC turbo kit for the Hayabusa. Take a look at the "exhaust system", the stubby large-bore dump pipe bolted to the turbine housing. Also note the giant fuel pump and four additional shower head fuel injectors to supply extra fuel. This particular kit is good for about 550 horsepower on a 1.3-liter (80 cubic inch) engine on gasoline.

I wonder if he thought that because so many Harleys have no mufflers and are incredibly weak?

thats dope! Hayabusa’s are amazing bikes. So smooth..

Wive's tale or not, I won't argue.

I have seen plenty of people take off the mufflers from motorcycles, just running the headers and ended up burning their valves. I am sure that they most likely did not properly rejet their carburetors after removing the mufflers either.

Those with more experience can give more information on how much back pressure you need to maintain with the 2.3L Ecoboost motor.

And that is also why I said that too. While I am use to working on motorcycles, I have not messed with turbo charged engines.
