Review on Agency Power AP C7 175 Stainless Chevrolet by Roy Whetstone

These tracks sound great! The fit and finish was perfect! I installed them myself in about 4 hours on the passenger side, you will need to remove the fuse box, loosen and relocate the coolant overflow, the driver's side is a bit tight but make sure you remove the stock manifold outlet and your dip with one Stock one, both stock headers, after the bolts are loosened from the heads, disconnect the crampons and center pipe from the main header and remove them from the underside. The new agency manifold fits from below and fits perfectly! You can still install both oxygen sensors and screw them directly onto your xpipe. You sound amazing. I noticed that the RPM's picked up a little faster and I only got about 10 miles on it before the check engine light came on like yours. I will publish the video on my YouTube channel.
