good product

I installed these on my 2012 G37 Coupe. Fitment was decent—took some effort around the steering shaft but nothing crazy. Once installed, the car feels more responsive and definitely pulls harder above 4K RPM. The sound is throatier too, especially at wide open throttle. Paired with a tune, it made a noticeable difference. So far, no leaks or issues.

Header and cross pipe 1997 Jeep Wangler 2.5

This header was almost perfect had to drill the first foward hole out a little larger to fit the bolt other than that it bolted on with easy. Use a long extension for the fifth bolt from the front. The cross pipe lined up beautifully. From start to finish was 3 hours.

Thank you for the attention to detail.
