hey man i seen where you asked if i painted my mirrors i never did maybe it looks like it in the pictures tho and i love the intake it was the only one that was worth a **** when i was trying to get one for my 07 cause for some reason the throttle body kicks off to the side instead of going straight out like every other vehicle in the world ha but i like it alot

Hey.
When did you get the mirrors painted. looks awesome, how much was it and where.
How do you like the S&B, can you feel a diff.

Well I've ran about 2 tanks now and the first tank was me hot rodding around with the headers. The tank I am on now my scan gauge shows 17 mpg over 200 miles with 50 of that being hwy, but I was going into a crosswind both ways so I only got about 20 on that (usually 23-24 on hwy). So I would say the mpg gains are there, the power gains are not noticeable without my scan gauge. only like 2 or 3 hp. My exhaust sounds WAY better now, got a nice deep roar to it. I would say that it is worth it though, in about a month I will know more about mpg's.

I could feel it pushing me into the seat a little in econ. mode, havent put my programmer in performance yet cuz i have a small leak to fix. There was deffinately a gain. As far as changing to 373 i would do it. My 4.6 can beat my cousins 5.4 and until my headers we had the same performance mods, so that would really help you out. The only thing is if you have a lift or someone to help you put the headers on becuase it took me and my dad (30+ years of automotive experience) about 12 or 14 hrs to do. Good Luck.

yeah i get about 17mpg driving on intersate mostly getting to work and the rest is just 45 around the house but i have my flowmaster single in dual out, intake and my programmer on the 93 setting i still have my stock 3.55s which help a little more but im going to swap to 373 but but how about any noticable gains with hp and torque

Hey.
Well I actually just got them on last night.
I went and test drove it with my scan gauge that displays horsepower and gained 3-4, and I dont have it to read torque yet, but i would assume 15-20 there. I already have the full dual exhaust so i didnt get the full results that the jba dyno sheet said which was 9 hp and 29 or 39 ft. lbs torque. I also got 18 mpg on the 4 mile trip that i made getting on it 3 times to see the hp. It will take a few tanks to know if this really helps. But if you want to know what i have done mpg wise, here it is.
All stock except true duals (got them right after i got the truck) 12 mpg
Fitch fuel catylist 13.54
Superchip on economy 15.31 (also switched to 90 octane from 88 this tank, savings in mpg pay for going to premium and then some)

hey man i seen on yer sig you have shorty headers did they help out with power or maybe even milage wise and what kind... im thinking about putting some on mine there just hard to find for this newer 4.6
