Had done my exhaust and open pod in speedwork, not really happy with the craftsmanship, they are even terrible than wei yip.

Get to main point, I had some question here. The exhaust setting they give me was like this
it was a straight flow, and I dunno why, I`m a automatic transmission. They said i`m using open pod, so I should use straight flow.

Anyway, The exhaust system by speedwork are using stainless steel piping and extractor only, the muffler and resonator part are metal spray...
