Default Re: Air Intake, Exhaust

I went with a the K&N "Fuel Injection Performance Kit" (57 series) and a Flowmaster American Thunder exhaust (with ceramic Gibson shorty headers).

I did the K&N first...I noticed a bit more response from the throttle and a bit more growl from the motor...nice.

The exhaust work was done about a year later...much better sound, maybe a little better throttle response and pick-up, but I could also just be 'thinking' it's better cause the truck 'sounded' so much better.

Just like Xotik H3, I got about another .5-.7 MPG after doing both. I've averaged 11.8 over my last 10,000 miles.

These CAI and exhaust are the first two mods I do to every vehicle. They're the mods that keep on giving...power AND MPG! Let that motor BREATHE a little easier.
