The Exhaust Bible Series is finally happening! Kevin told you guys last year that he is going to test every single exhaust option we could get my hands on, but we instantly ran into an issue and have been putting it off. That ends today though. We are starting it off at the very beginning with the stock exhaust. Lets see if we can make the stock catback exhaust on the GR86 sound good with an aftermarket header and front pipe!

Installing an aftermarket header is one of those upgrades that can make a major difference in exhaust flow, turbo response, and overall performance when paired with the proper supporting modifications and tuning. While the install itself is fairly straightforward, exhaust hardware can be stubborn due to heat cycles, corrosion, and age.

This guide walks through the basic header installation process, the tools required, torque specs, and what to do if one of the factory studs breaks during removal.
