Default Exhaust back pressure true or not?

Does any one out there know if there is any truth to the story about these modern trucks exhaust system all set up to accommodate exhaust back pressure. I was going to have a new y-pipe installed and got talked out of it by the Muffler guy. I was think of installing ceramic coated shorty headers and keeping the factory CATS on then having true dual installed after the CATS on my 2013 Ram R/T instead of expensive LT headers. I'd appreciate some good feedback on this and thanks in advance!

Okay well firstly I would recommend saving up for the long tube headers cause they are so much better. Buying shorties is a waste of money because they essentially do the same thing as the stock manifolds. As for the y pipe definitely get it because the factory crimped Exaust into one is stupid lol. If you get the American racing headers you will get high flow cats and a built on y pipe. <--- So worth it a must do mod, especially on a r/t

Back pressure? No its not good. Velocity? Keeping it high is good. People often use the terms as the same. Say you put dual 5 inch exhaust on your truck. It wouldn't be good, the velocity would drop off and the exhaust wouldn't flow out the back well. Put a single 1 inch exhaust on, velocity would be great, but back pressure would be sky high and choke the engine. Some where in between is best. My challenger came with true dual exhaust so it's not going to hurt your truck, but how much it will help, I can't say. I'm not that familiar with how the factory stuff flows.

Btw, everything I said above applies to gas engines, not diesels. Turbo diesels can have huge exhausts and it doesn't hurt performance.

the guy that talked you out of it isn't wrong. the new engines are setup to run within the set parameters. including back pressure from the exhaust. if your goint to get a good performance exhaust you will want a tuner to help change the tuning and get the most out of your exhaust, and fastram was right as well. longtube headers will give better performance and better flow. your engine relies heavily on the computer and tuning to run properly. if you increase the flow of exhaust gases the o2 sensor reads the computer will see it as a problem and make changes to get the normal readings. a good tuner will allow you to make the necessary changes to get the best possible performance out of your engine.

^^^ He is right. In a sense the factory Exaust is set up for the performance and tuning from factory. When you switch to a cold air intake, a cat back Exaust and some nice longtubes, with a bigge throttle body or whateve future mods you plan to do to make hp you need to tune it so it all works with you and not against you. A trinity 1000 seems to be the best tuner for mods. Especially with a hemi fever tune for the mods. When I first started messing with my truck there were a few glitches and engine light went on. After a fine tune it made one hell of a difference.

When I see this:






I think anything is better than stock.. screw stupid stories of back pressure no back pressure... here is a Dyno from the guys who make long tube headers.

as far as the question goes my dad use to tell me the same thing every time i did something to my s10 in high school. Son the engineers designed that truck that way for a reason. with that being said yes their are certain parameter the truck was designed for but i think what he was getting at is replacing the part where the y pipe meet up isnt going to give you much gain.yes the air flow is disrupted by the kinks in it but you still have 2 2" tubes throwing 4" of air in a 3" tube so all you would be doing is giving the air a smooth transition in one place but the exhaust fumes still have to collide somewhere and the is what gives you some of your back pressure

If I were you and I had the money(still saving up after last mods lol) I would go long tubes high flow cats x pipe going into true dual 2 1/2" pipe(muffler of your ears choice) with air intake(ram air or cold air) and a tuner.

Nailed it, it is all about the velocity, it allows exhaust gases to be scavenge out. Keep in mind that flowing exhaust gases is different simply because the gases come in pulses as each cylinder discharges. Each exhaust pulse is a pressure followed by a vacuum.

Thanks guys for the input. If I go LT headers it will run around $2100 which also includes having them installed. And unfortunately money does not grow on tress so I will have to save and wait. I had mid length headers on my old 2002 Z28 Camaro with no cats and oh wow it made a difference! I understand about the programmer and that will be another 600 so it will take even longer to save but you guys have helped in my understanding of this. Keep up the good advice!
