Title says it, which is better? Single exhaust or dual? Why?

Which muffler? 40 series or 50?

Does size of the exhaust make a true difference? I've heard just about every differnet option.

Looking for better airflow to improve MPG and horsepower. Occasionall, I need to tow something and anything of any weight seems to bog the truck down as it sits.

 

I personally went with a Magnaflow cat-back system. It definatley improved the power. Better acceleration, and i even gained a little in the gas mileage dept! I just have a single exhaust at the side. They do offer a dual kit as well. If you like a deep throaty tone, with little drone, Magnaflow is the way to go.

 

junk master suck, save your money. i had the cherry bomb and loved it until it rotted away, than had the junk master install, what a piece of ****, i have the 3 inch single catback, junk. all it does is sound good, nothing else. i lost torque and some power from the system. cant wait to cut it off and go back to a better system

 

I like dual exhaust myself, but thats just me

 

i went with dual exhaust my mbrp and love it look into that if you wants its a cat back system and sounds awesome and was cheap. it is a 304 stainless steel with lifetime warrenty added more power and a little it on the mpg only thing is you will want to hear it roar and thats where you loose the mpgs

 

canadiandodge: Why did you go side instead of straight back?

 

i like the look way better then out the back personal preference

 

I have the magnaflow single side exit and love the sound. As for performance gains, I have no idea as my truck was 2 weeks old when I put it on lol.

 

nobody really likes flowmasters...

it's the truth...

 

I have a Flowmaster 40 series on my Z, and I have a 40 series ready to go on the Dak. The Z sounds amazing with it, so I have high expectations with the Flowmaster when it goes on the Dak. Oh, and it'll be a single 3" inlet, dual 2.5" outs.
