Been wanting to put on an exhaust and intake on my 09. After I first got the truck new in winter of 09 I put in a K & N air filter and it put my truck into limp mode. I was curious if I upgrade my truck with exhaust and intake, would a tunner be need too?
Awsome. Now what exhaust would you recommend. Not looking for something with a lot of bark. I actually enjoy how quiet it is now. Something close to stock. Not lolling to turn it into a racer. Just some more power and maybe better mielage.
You don't need a cold air intake unless you are going to be making more than 500hp. I have a 5" magnaflow downpipe back system with a muffler and it is quiet when cruising and sounds really good when i get on it. I would also suggest EFI live for your tuner.
Hey Farmer.....As Gweber said, you don't need aftermarket CAI unless you're hitting 500+ horsepower. Just do the exhaust, EFILive & something like Edge Insight CS or CTS w/egt probe. I also blocked the EGR. The last couple tanks I hand calculated back in September were right at 21.3mpg running my 90hp tune. Heck, last time I towed my enormous toyhauler I averaged 15.1mpg on the 65hp heavy tow w/turbo brake tune. Very satisfied with these truck mods. Money well spent. Good luck to ya !!
