Great Performance, Easy Installation

This exhaust gave my car a great boost in performance while sounding amazing. The installation process was surprisingly easy, even for someone with limited automotive knowledge. The only downside is that it's a bit pricey compared to other options in the market. Overall, I'm extremely satisfied with this purchase and would highly recommend it to anyone looking to upgrade their vehicle's exhaust system.

Pros
  • Improves exhaust flow and overall performance of the vehicle.
Cons
  • Installation requires some welding skills and tools.

When using simple round manifolds on large square port block inspection heads (1974 454 in my case) 5911 gasket is best

I was between them and copper/aluminum gaskets, port sizes were crucial. When using simple round manifolds on large square port actuator heads (1974 454 in my case) the 5911 gasket is best suited to accommodate the two shapes. They're perfectly sealed, but don't count on them being reused. Once compressed, they will usually leak if you remove the head and try to reuse them. Plus, you can cheat with them with Permatex Ultra Copper silicone.

Pros
  • Expanded steel core provides stability and maximum torque retention to avoid gasket failure
Cons
  • Protection
