Not what I expected from Corsa

I haven’t installed it yet because it was supposed to have a female inlet...read moreI haven’t installed it yet because it was supposed to have a female inlet and a male outlet but came with two female fittings. When I contacted tech-support they told me there’s should be a drainage hole to tell me which one was the inlet and which one was the outlet but there is no drainage hole. Tech-support then sent me a build sheet which shows metal screens welded which are not included and the drainage hole which was not included. Basically this is not built according to their own build sheet. Tech-support told me to drill a hole in the muffler…. What?!?! Hopefully they respond soon, I’ve requested to return the muffler and have a new properly built muffler sent but still waiting on response.
