4.3L V6 Vortec Headers vs. Stock Exhaust Manifolds
Upgrading from stock exhaust manifolds to 4.3L V6 Vortec headers is a smart choice for anyone looking to improve their engine performance. Stock exhaust manifolds often create more restrictions in the exhaust flow, which can reduce engine efficiency and performance. Here’s why upgrading to performance headers makes a significant difference:
Improved Exhaust Flow:4.3 V6 headers are designed with smoother bends and larger tubing, allowing exhaust gases to exit the engine more quickly and efficiently. This reduces backpressure and improves overall engine performance.
Enhanced Power and Throttle Response: By reducing exhaust flow restrictions, headers increase engine efficiency, resulting in better throttle response and more horsepower.
Better Fuel Efficiency: With improved airflow, your engine can perform more efficiently, potentially leading to better fuel economy, especially under hard acceleration.
Reduced Engine Stress: Stock manifolds can cause heat build-up and excessive backpressure. 4.3 Vortec headers are designed to reduce these issues, which can result in less strain on the engine components over time.

4.3 in a 91 Toyota fits except for the steering shaft
I got the 4.3 out of a 98 2wd s10 and put in a 91 Toyota 4wd pickup. Everything fits perfectly the only problem is the long middle tube on the driver header goes right in the way like I mean right in the way of the steering shaft. So I’m gonna have one of a kind custom driver side header lol

Tight fit
I put these on a 2004 Blazer. They will work if you can cut off the EGR tubes and weld up the holes. They are built very well and installed in the same location as the stock manifolds. Use a little high temp silicone at the contact areas and they seal completely. I am very pleased with these and love showing them off.

Great product for the price
I bought these for my 2001 2wd 4.3 s10 because the price was so much cheaper than 2wd headers and they fit just with a lot of time and patient and i would definitely recommend having mechanical knowledge if you try and attempt this, because you do need to jack the motor up to get driver side manifold out and header back in.

The product was spot on with fitment and performed like it was supposed to. Well worth the value.
Thank you for your comment and I look forward to receiving your feedback pictures!
Put this catch can on my ’21 Q60. Install was straightforward, hoses lined up perfectly. Engine feels smoother on acceleration, and I’m confident it’s preventing future carbon buildup.
Put these on my ’10 G37 Coupe last month. Fitment was spot-on, install went smooth, and no rattles or leaks after a few hundred miles. Noticeable bump in power and a deeper exhaust tone without too much drone.
Installed these on my ’08 G37X over the weekend, and I’m impressed. The fitment was spot-on, no weird gaps or alignment issues. Throttle response feels snappier, and there’s a nice bump in low-end torque. The sound is a bit more aggressive but still daily-driver friendly.
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.
