DIY 1998 Volvo V70 Exhaust Manifold Replacement

Alright, my exhaust leak has been chronic for a few years, as it turns out, it is a leak at the Flex Pipe, just in front of the Catalytic. It gets worse and noisy, so I decided to tackle it.

Search forum for “OBX Exhaust Manifold” brand, about $200 on ebay etc., many people seem OK with it. I could not find any long-term report (such as 5 years or more) of happiness with OBX, also from my research the Honda people have some issues with OBX. Since this is a job I don’t want to do again for another 10 years, I decided to go with Volvo OEM because the OEM held up for more than 10 years!
