H3 HUMMER L52 engine 5-1 exhaust manifold fabrication timelapse| Rusty collector into a trick header

In order to rebuild an old, rusty motor, you need to go through every single component. As a matter of fact, you'd be better off replacing factory parts with aftermarket goodies. On a Hummer H3, replacing the stock cast iron exhaust manifold is a necessity, due to it being prone to cracking. I've made a high-flow replacement manifold with equal length runners using AISI 304 stainless steel. Each runner is 42.4 mm wide, wall thickness is 3 mm, while the 5-1 merge collector is 60 cm long. These specs allow for increasing engine efficiency and improving exhaust gas flow out of the cylinders on this inline-5 L52 Vortec 3500 GM's engine. This exhaust manifold is durable enough to allow for installing a turbocharger. The manifold was made using a TIG-welder fed with argon. This timelapse video shows the entire process of how the exhaust header was made. For more comprehensive information on the key stages of developing and welding up this manifold, see my series which includes the following videos: 1. Making a jig for welding an exhaust manifold with dimensions identical to stock. https://youtu.be/VGiX4U52iDE 2. 5-1 merge collector.

Whoever is first to answer the following question will receive a cash prize (5$ transferred to bank account or cell phone balance): - how exactly did I screw up (multiple times) after first test fitting the mock-up manifold to the car? #ZergBush #fabrication #welding ★★★★★★★★★★★★★★★★ ✅ My instagram: https://www.instagram.com/sergbush/ ✅ FB: https://www.facebook.com/Serg.Neo.Bush ✅ VK: https://vk.com/neomadc Sound: Epidemic Sound https://www.epidemicsound.com/referral/sipwlm/ Music: Martin Sehnal https://promodj.com/martin.sehnal Liked the video?
