I have a 2011 Dodge Ram 1500 Sport and I was wondering if straight piping it would A) make it have a loss of power or B) make my truck loose fuel faster ?

I was told by my friend that that it would have a loss of power because he did it to his ford and he lost power :sad:

Well I have had a few trucks straight piped and it does eat on gas compared to running a flowmaster or magna flow. As far as power it is little to be gained or lost with just the pipes. Headers make the difference as far as exhaust goes.

I've mentioned before that I come from an F-150 background. Yes, the Ford 4.6 and 5.4 need some backressure to work at their best. Adding straight pipes to them will cause a lose of lowend hp and torque. Not sure if the Dodge engines have the same results.

the loss of power he was talking about is indeed due to the loss of backpressure. you need that to pull away quicker from zero. my dad says he did straight pipes on his camaro and he had a lag getting off the line cause of the loss of backpressure. as far as your truck i dont know how much it will affect it. you could just get a different muffler if youre looking for sound.

Its a trade-off. You will lose low end, but gain a little in the top end.
For daily driving would i do it? No. For a track vehicle? sure.
Fuel consumption is regulated by your right foot.

You won't lose power (at any rpm) or lose fuel(not sure where you heard this lol).

The backpressure thing is not correct, backpressure is always bad for power potential at low or high rpm. The reason many people experience a loss in power with exhaust changes is because they increase the diameter of the exhaust pipe too much. A larger diameter pipe has slower velocity of media flowing through it as compared to a smaller diameter pipe. You want I high exhaust gas velocity because it helps "suck" the exhaust out of the combustion chambers, giving more power potential. The stock exhaust size is about as good as it gets, not too small, not too big. Differences in power output between some of the best mufflers and straight pipes will vary by less than 5 hp.

Back pressure necessity is a myth for 4 strokes.
Reversion is a different story

i duuno...my truck runs by people straight piping....they're louder...I'd rather be faster...

Thank you for your help I might consider straight piping my truck in the summer thanks again!!

Yeah well I could straight pipe my chevy aveo and you'd still be faster, but that doesn't mean straight pipes give less power lol.

Seriously though, I'd bet if you pulled your muffler off and replaced it with a y pipe you'd run the same times you run now.

Is that 12.10 a new time?

 

[snrusnak]

If mufflers gave more power than straight pipes, stock cars, open wheel, drag cars, etc... would all be running with mufflers.

The nice thing about straight through mufflers on a street car is that you get about 99% of the power of a straight pipe, but only say 50% of the noise.

Maybe it's just me, but "most" street vehicles I've heard with straight pipes usually sound downright obnoxious in most of the rpm range when trying to drive on the street. Unless the pedal is flat on the floor, the exhaust seems to have a variety of burps and farts that basically sound like crap. With the availability of so many high quality aftermarket performance exhaust components out there that sound so good and don't eat hardly any, if any power, why go with such a *******, straight-pipe system for a street vehicle?
