I didn't notice much of a diff in performance on my 3.7L V6 when I installed the CAI but I did get my exhaust done less than 24 hours after the CAI and well I noticed a diff after that... and both mods make the truck sound alot meaner and leaner... granted I have a quiet exhaust system...

 

yeahp can't wait to put my headers on....i have them but don't wanna put them on just yet! cause 1) still have my warranty and it only has 10K on it...I know some guys on here will say....Just through it on your motors ready...but yeah not just yet...got my 180 degree thermostat put in yesterday...got Stage 1 on order...got my intake in so by this weekend...intake, thermostat, and stage 1 will be on by Sunday! so hopefully that will make my truck breath alot better and run better and get better Gas Mileage MAYBE....but yeah by next summer i should have alot more done...and hopefully by next fall have a Supercharger on it pushing like 5-8 pounds of boost!

 

well I will...its called i'm lazy and yeah not that tecnically and computerly inclined as some of you people...lol i'll get my truck pictures up shortly!

 

Ah geeez here we go again...

I'll Get pictures of my dakota up soon enough...i never have time to do anything...to busy...with school and working...not an easy task iight...

 

Hold off on the side bar conversations please.

4X4, your warranty won't run out with headers on. You'll be ok. It may, on the other hand, run out with the S/C on it since you have to crack open the engine and change out the cams and a few other things.

 

yeah....i know that just uhm....you know my exhaust makes enough noise in the cab as it is and yeah putting headers on it right now wont' exactly help that out!

 

Yeah, we should try to keep it in the other threads though. tbh this thread could really use some cleanup where it's stickied and really only supposed to be about mods. We've taken it a bit off topic...[&:]

 

ya, that it does need

 

Thought you guys might want to see these. That's about all you can see of the headers once they are installed, not too exciting. The dyno graph shows a 42 lb-ft torque gain @ 2500rpm & 20 hp gain @ 2500rpm & 5500rpm, and you feel EVERY bit of it! The parts installed are Doug Thorley Headers (not Doug's Headers) shorties and a Doug Thorley Headers cat-back exhaust.

To explain the graph, the BLACK line is my all stock 2007 4.7L (non HO)2wd Dakota, the RED line is the headers only & the GREEN line is the headers & exhaust.
