Alright, what I have here is a roughly 3ft section of 3" steel pipe and two custom, laser cut 2-bolt 3" exhaust flanges. So if you have a welder or know someone that could weld for you for cheap, add some gasket maker and a 3" test pipe could be yours.
This will save you quite a bit of money and won’t be shitty like the ebay test pipes. This is great for a custom swap (s-chassis rb swap) or for people with custom turbo systems and don’t want to pay for a custom catalytic converter.
Note: the flanges on the pic aren’t welded on, they are just sitting on the pipe.
Price: $40. Those flanges are laser cut and aren’t cheap.
