I installed this in my car about 6 months ago and then ran the tune on my DiabLew built i3 Sport Diablo Tuner (highly recommend). Pros: SIGNIFICANT boost at low frequencies. . Slightly hoarse sound. Cons: Had to finish the welds on the flanges, too sloppy for the bolts. Flange gaskets were not included. You sent the wrong manifold gasket (I have an 8 cylinder, not a V6). Regardless: It's a PITA setup simply because the Camaro doesn't leave much room on the left and right banks. Although there is more space on the right. Conclusion: I would do it again. I love the result, I love the sound, I thought the upgrade was worth it simply because I can feel and hear the difference after a day of work and less than $400. Observe the screw tightening table and use a torque wrench!
