Installation was easy & I'm by no means a mechanic. Prior to installing this, acceleration seemed louder in the cab & the bulk of the noise came from the engine compartment (I already had a cold air kit, but factory exhaust). Now the truck has more power, inhales/exhales easier & acceleration noise is more from the exhaust & sounds a LOT better. The touring sounds beefy at startup & acceleration (not overpowering) & is quiet at cruising speeds. Perfect!! Would buy again in a heartbeat.
A must buy for any vehicle!
These headers instantly provided more HP and gas mileage. If you are on the fence about purchasing headers, you shouldn't be, these headers are exactly what I was hoping for. I've purchased a cold air intake, gibson dual exhaust and superchips power programmer over the past years. The headers provided the most noticeable HP and MPG gains. Only issue was the lack of detailed instructions when removing exhaust manifolds. Additional tools required, O2 sensor removal required and not mentioned.
quieter then i thought
Listened to a lot of videos on the flow master 50 series for Chevy trucks and they sound a lot louder in video then in real life. Also bought a k&n intake and installed it same day. It has a pretty good tone and all the piping fit perfect. It took about a week for the truck to get used to it. I had a huge lag in throttle response for about a week. Sounds good enough though I guess.
