Great upgrade for my vehicle

After I put it to the test, I noticed a significant improvement in my vehicle's performance. The exhaust system now flows better, and the power gained is notable. The aluminum build also reduces weight, and the finish adds a sleek look. However, the installation might require extra hands and experience under the car.

Pros
  • Durable and lightweight due to being made of aluminum, providing better performance and fuel efficiency
Cons
  • Potential for higher noise levels due to increased exhaust flow and lack of sound-dampening materials

Not so great. fits replacement parts

later I have used similar aluminum manifold gaskets in the past and had no problems. You screwed up the first run. Very disappointed.

Pros
  • Manifold Gaskets
Cons
  • I'll write

Works well on a 78ft Corvette!

After installing the header kit and upgraded dual exhaust on my 78ft Vetta, the progressive noise got louder. Knowing that typical exhaust gaskets are prone to catching fire, particularly due to the higher temperature of aftermarket headers/exhausts, I settled on an aluminum gasket kit. The engine was much quieter immediately after installation and the new seals did not show any signs of wear. The installation itself was quite easy, no problems were noticed. Although it was somewhat unclear…

Pros
  • Automotive
Cons
  • No Instructions
