Dual exhaust

[richmill20]

Has anyone installed a dual exhaust on a Titan? If yes did you see any performanc e or mieage improvement?

Do you mean true dual or single in to the muffler and dual out? From what ive heard true dual relieves too much back pressure. To get the most power gains single is the way to go. Not sure about gas mileage on the dual though.

I went with just a muffler replacement. Sounds just like the stock sound, just louder. No loss of low end power. MPG never really changed.

my 2007 has 2 pipes into the muffeler and 1 out. I was thinkig of 2 muffelers and 2 tailpipes. I tow a 6500 lb trailer so any little bit more power helps

These trucks love backpresure to get out of the gate alot faster.You cant have both as of what i've seen.

my mpg has gone up 2 since adding the intake and exhaust, dont know if its just the intake though. i really like my setup with single in to the muffler and dual out, sounds and looks bad A**

True dual relieves to much back pressure. I got the JBA evol catback system because I was told it gave the biggest performance gains without any low end loss.

All the Titan needs is a single catback. Add an intake and yes you may gain 1 or two miles more pg.

I went with single in dual out 2.25" pipe diameter. Went with small diameter piping to maintain backpressure.
