2010 Camaro SS Cold Air Intake & Long Tube Header Installation

August 2, 2010 1 comment

Now that the Camaro is almost a week old, I figured it is never too soon for additional horsepower, right? For the first round of mods I chose to install a Roto-Fab cold air intake system (CAI), and a set of Kooks long tube headers. I followed the rule that if you allow your engine to breathe easier it will better produce more power. The LS3 is no exception to this rule.

I decided to install the CAI first. This is about the easiest mod that one can perform; installation takes less than one hour to complete.

I have to give GM credit here. The engineers did what appears a pretty good job on this stock intake system. There are no severe bends or restrictions at all, and the lower part of the air filter housing contains a large port to suck in cold air. I was beginning to wonder if I would see any gains by installing the Roto-Fab setup. After reading several forums, and looking at dyno test results for the Roto-Fab, people are seeing peak gains of 15 hp and 11.7 ft/lb torque. The average hp and torque gains were 11hp and 11 ft/lb across the RPM range….sold!

Now for installation of the Roto-Fab system


Now for the more difficult of the two mods, the Kooks long tube header installation. I won’t go into all of the details of installing these headers, but basically I followed the instructions found here: How To: Install Header System on a 2010 Camaro SS

Here are the stock exhaust manifolds/cats removed from the vehicle

Here is a side by side – Stock vs. the Kooks long tube header with off-road connection pipe

The overall length of the Kooks header with off-road connection pipe is the exact same as the stock setup. This allows you to bolt right up to the factory exhaust (which I did) or install an aftermarket exhaust with no cutting or welding required. This setup removes the catalytic converters from the exhaust system, so custom programing of the PCM is necessary to tell the computer to not to set a check engine light due to the missing cats. Even if you choose to go with the catted version of these headers, a custom tune is required to allow you to utilize the full potential of these headers.

This combination of CAI, headers, and custom tuning is good for about 50 RWHP! At idle and when cruising, you can hardly tell the difference in the sound of the exhaust. However when you mash the go pedal it becomes apparent that the headers are installed, the exhaust comes alive. As for a cat back exhaust, I am probably going to stick with the stock setup for now. You get 2.5″ true dual exhaust with an H pipe from the factory. Adding an aftermarket cat back exhaust only adds 5-10 additional horsepower, but makes the exhaust considerably louder. I kind of like the sleeper factor with the stock setup anyway!
