Exhaust for 13 taco

What??? Both Turbocharged and Supercharged engines are "forced induction" but I have no idea what you are talking about with the cylinders downwards and the air in/out. That doesn't make any sense. As someone who has owned several supercharged and turbocharged cars I can tell you that both do the same thing (add more air so you can add more fuel and therefore make more power). They just go about it differently. A supercharger uses the engine's accessory drive to turn the impeller (on centrifugals or the rotors on a roots-type) while a turbo uses the heat from exhaust gases to turn the turbine which then turns the impeller. Turbos tend to make more power than supercharges (with all other things being equal) because the supercharger robs the engine of some power just to turn the blower where the turbo uses waste (exhaust) to turn the impeller.

One does not inherently make your pistons (that is what I am assuming you mean when you say cylinders) move down any faster than the other. And the other doesn't move air in and out any faster than the other (that is handle by the pistons and cam(s)).

 

If I wanted to just cut out the stock muffler and have a Magnaflow welded in, would I need 2.5 inch in/out, or 2.25?

you did a better job of explaining it yeah, and im not saying youre wrong, but i took an engineering class at my university, and the forced air does accelerate the pistons

the more air and fuel allow for more combustion, which inherently force the pistons to move faster. which is why you have to control the fuel injection and the boost, because if you don't youll either create combustion too early and not allow for max power because of lack of space for combustion, or you do it too late and the power gain is too late.

 

I'm not trying to bust your chops or anything like that, but this is an area I have a lot of knowledge in. Piston speed is not determined by forced induction and it certainly doesn't matter if your car is supercharged or turbocharged. Piston speed is based on the length of the stroke and the RPM of the engine. Your piston is moving at the same speed at 4000 RPM whether you have a turbo, supercharger, or are NA (naturally aspirated).

Now, the more air and fuel you have the more power your engine will (theoretically) make and more power will help your engine accelerate faster (in revolutions per minute); but adding either type of forced induction will not change piston speed. The only thing that makes your piston move faster is either more RPM (revving the engine) or if you change the length of the stroke (longer rod/stroker crankshaft). Forced induction plays no role in piston speed.

There is a difference in the type of exhaust you want based on the induction method of choice. With the turbo being exhaust driven you can say that it is the most influenced by the exhaust. Generally NA motors require more back pressure to keep the exhaust flowing (and scavenging). Supercharger create more exhaust (than NA) and so a higher flow exhaust is needed to expel the greater volume of exhaust. Turbos also create more exhaust than NA but because they themselves are a restriction in the flow and need to flow to allow themselves to spool, they need the highest flow exhaust of the 3 different types of inductions discussed. I hope this helps clear things up a bit for anyone interested.

 

Again you explain it better haha an engineer that learns all the theoretical and nerdy side of things its hard to translate. but yeah youre right

 

I have Magnaflow part #12256, 2.5" in and out, welded on stock pipes. Best $60 I ever spent.

 

Thanks, Khaos. They are now $90 at Summit.

I called a local shop about doing the work late last year when I first got the truck. He said "oh man, you want to cut the muffler out of a 2013 ???"

It kind of scared me from doing it then for some reason. I'm going to go for it now though.

its not a big deal...............if HE was scared, then go to a dif shop. Its a simple process.

 

No, because the other cylinders are on other strokes. For instance one cylinder might be filling with air but another would be on a compression stroke, so it would be fighting to compress the air. Remember the pistons are not independent, they are all attached to the same crankshaft so one can't speed up independently. Again, the only things that determine piston speed are stroke and RPM. The type of induction has nothing to do with it.

 

Yes it does, the increased air flow and fuel allows for quicker piston movements, hence faster acceleration, which is more power. You go from 500rpms to 5000rpms quicker with a turbo/super.... Why? Because you're pistons are moving/accelerating faster. How do they accelerate faster? More air and fuel which allows for a bigger combustion, a bigger combustion allows for quicker movements.

 

You are not understanding the difference between engine speed and piston speed. Your engine may and I stress may, rev faster but your piston moves at the same speed at a given RPM no matter what induction system you have. Your piston will not go any faster than the speed it is going at redline. Unless you move redline higher by fortifying the motor for more RPM. Your piston moves at a given speed at a given RPM. End of story.

 

Do you really think compressed air is strong enough to move a vehicle? Then why do we use gas? Just push compressed air in and out of the cylinders and the car would go, right??? Wrong! Compressed air, especially at such lower PSI (what 25 PSI max?) isn't enough to make our engines move the cars. You need the fuel that causes an explosion to get the cars, or in this case trucks, to move. You guys are really kidding yourselves if you think pushing compressed air into the engine is enough to make the pistons move and the vehicle to move. Don't believe me? Try it. Get a compressor and stick it in the spark plug hole and see if the car moves.

You guys really have no idea what you are talking about. Sorry, but you don't. AGAIN: your piston is moving at the same speed at any given RPM no matter what power-adder or lack of power-adder you have.

 

Get one from Amazon dude. I paid $67 shipped from Amazon Warehouse Deals for one new in box. Always go to Amazon first when looking to buy anything.

It took maybe 20 minutes to get it installed. Magnaflow mufflers break in, so keep in mind when you first instal it that over time it will grow deeper/louder.

 

Wow, you really don't have a clue. Compressed air is NOT strong enough, combustion is needed... with that being said, I am done trying to explain this to you guys... good luck with whatever you do with your rides.

 

Dude these two guys still don't get it. It's been several hours now and even the cows in Castaic probably got it by now.

Piston speed is based on the length of stroke and rpm of engine... plain and simple

 

There are no cows in Castaic, and I hope they got it.
