3.6L dual exhaust installed

[Smerberj]

I recently had "true duals" installed in order to see if I'll gain any HP, Torque, or MPG. Check it out.

I'm currently sitting at 296 HP and 280 TQ to the wheels, and 23 MPG average, my truck goes into the Dyno next Thursday.

The system sounds way better than expected, it's actually very quiet and only gets loud at wide open throttle and the best thing is NO DRONE AT ALL.

Wow! It looks great! Seems like they really did a great job!
Glad to hear it's everything you want, now we just have to wait and see what the Dyno says.

Any update? Do you have a link to the exhaust you bought? Thanks! Also, do you have aftermarket rims? I have 20x10 and average 17 mpg at best. Thanks!

Crap, I completely forgot about the forums guys my bad, I've been busy moving and have been up and down Virginia like a bat out of hell. I need to find the dyno sheet but what I have recorded on my phone is a gain of 6 horse power and 9 Torque. It wasn't as much as I thought it would be considering how much more torque(E) it feels in the lower RPM range. My HP and Torque average with the single exhaust was 296/280 and my average after the dual exhaust was 302/289. The absolute best mod for torque IMO was the RIPP coil packs, those things are awesome. Would I do it again? Probably, I like the torque and I love how it sounds damn near stock. MPG wise, can't really tell, but now that I live 3 miles from work I only commute in the city and I'm averaging between 21.8 - 22.4. I can easily keep it at 22. Not bad for a 5,000 pound truck (4,998 to be exact).

I bought 2 Magnaflow mufflers, part # 11255, an exhaust X pipe (Amazon), and 12 inch black tips. I have the stock 20 inch night edition wheels on the stock bridgestone duelers (I think that's the tire, it's a generic highway tire).

Is that all city driving? what mpg were you getting before the 20x10 rims?
I only ask because right now I have stock rims on my 19' Big Horn 4x4 Crew V6 Etorque and get well over 24 sometimes 25 mpg back and forth to work, 32 mile round trip, and I was thinking of getting some 20x10 rims....but maybe not if its that big of a hit on mpg!

I have 20x10 factory wheels and get 22mpg, mostly highway, about a 10 mile drive. Lowest I've seen was 19 when I first got the truck.

I have non-stock 20" wheels with the factory Duelers, just did a few hundred miles with the cruise set at 110kmh/68 mph, and got right around 22 mpg.

 

[User_67930]

That makes me feel better!
I might pull the trigger on a set of rims. Thanks guys!


BTW, to the OP that is an awesome dual exhaust setup, great job. Any sound clips?

I live 3 miles away from work so my driving is easily 80 - 90% city and 10 - 20% highway.

Sounds cliche but what is your driving style? Also, I'm assuming you have the 3.6L? It's been hot the past couple of months which means my A/C has come on and my stop start has been turned off, this is causing me to get 20 - 21 MPG.

I like the gas pedal.
but on highway i use cruise alot.
ac is almost always on
