Disappointing quality, avoid these headers

these headers are not up to par with other automotive parts. They fell apart during installation, causing further delays and expenses. The only upside is that they come at a slightly lower price, but the poor quality makes it not worth it..

Pros
  • Pro: Lower price
Cons
  • Con: Poor quality, fell apart during installation

Improved Exhaust System

The Flowtech headers improved my car`s exhaust system immensely .The sound is deeper and louder giving my vehicle a more powerful feel. The installation process was a bit challenging, but once completed everything fit together perfectly. i highly recommend these headers for any automotive enthusiast looking to upgrade their exhaust. The only downside is that they are a bit expensive compared to other options on the market..

Pros
  • Improved exhaust flow and increased horsepower
Cons
  • Higher cost than some competitors.

Do not buy these for the Cutlass Supreme 86 5.0L

I bought these for our 1986 Cutlass Supreme 5.0L/307. Landing on the engine is great until you want to put the starter! So I decided on a mini starter. still doesn't fit. After a few hours with BFH (pipe half flat) cleaned the starter. They baked the finish (don't know why they can't factory paint them with header paint) and painted them with header paint. Thermal cycles passed on the engine stand. I was about to install the engine in the car and hit the frame from both sides. The driver hit…

Pros
  • Port Sealed O-Rings
Cons
  • Large and Bulky
