dual seems to be most popular of the two. any major reason, or is it maily the looks? anyone knnow the advantages or disadvatages of the two?


can anyone clarify on the "duals usually result in torque loss" myth or fact?

 

Most people will agree the best solution is to replace the factory y-pipe with a flomaster piece, replace the garbage-can OE muffler with a 3" SI/SO performance muffler and a single 2.5 or 3inch tailpipe.... like a Gibson sweptside type system... not that I condone any single manufacturer... Gibson mufflers (non-stainless) seem cheap.

Unless you're running 350-500+ HP this is the most economical and powerful combo.

While some duals may sound nicer (subjective) you have extra pipe = more weight, more expensive for nothing.

In case you missed it we've discussed it to death here: https://www.f150online.com/forums/sh...threadid=73370

My 2 cents.

 

i have a single 40s 2.5" flowmaster muffler with dual 3" crome tips. I'm happy with mine sounds good course not much for hp/torque if anything. I was just looking for the sound on this one, not the power

 

My '97 4.2L responded very well to cat back duals. I noticed right away that my truck felt lighter accelerating from a dead stop and passing on the highway.

Back pressure is a big consideration. Reduced back pressure is good for high RPM horse power but very bad for low RPM torque.

A high flow muffler with a single 3" exhaust pipe should give a small increase in noticable power and sound good as well without much of an expense.

I have duals because I liked the look of 2 shiny, slash-cut tips comming out the back. It's a Dynomax Turbo muffler. The pipes are 2.25" and the tips are 3.5". Sounds very good as well.

 

My theory.......

Girls have how many *****? Guys are usually(not always) the ones who want dual exhaust. Let your mind and the laws of nature answer this question.

Ha Ha

 

OK, Babyblu...I give up...

What's the answer?...

P.S. I guess that's why I've got some "big tips" on the end of my pipes.

 

I personally had my Y pipe split by the o2 sensor and had two going inot the muffler and two going out. The only one that I could find to do this was a brand called Mean Streak. I have heard that Flowmaster now has this too. I highly recomend two going in and two going out of the muffler instead of a single in and duel out. MORE POWER!!!!!

 

I am having mine tomorrow. I am getting a Vortex Cherry Bomb with one in and two out. Have had a couple of buddies do it and the flow restriction is basically nill. They said it seemed to increase power a bit and is costing 300.00Can.

We'll see tomorrow??

 

Mine actually only cost $225
