Had the motor rebuilt and put on a 3inch dump pipe but couldn't afford the rest of the exhaust.
The engine builder broke out the digital micrometer and measured the inside diameter of the stock exhaust system and the downpipe.
The bolt holes all mated up perfectly to the stock exhaust system, with the use of liquid gasket there was a perfect seal so no exhaust leaks.

It seems they are not all created equal. Did you have wastegate troubles?

To the OP, it is a quick and easy job to grind the downpipe to get rid of the sticking wastegate trouble if you get an ebay pipe.



where did you grind?
