Weird. In your pics, the pipes look like they are level side to side. I was originally going to get this exhaust, but many pictures that I found online showed that the LHS tips were quite lower than the RHS. Even the pictures on their website (red E92) shows this quite clearly.
That's why I decided to just go with OEM exhaust mod (bypass method). A bit cheaper, and painted black, it looks fine to me. Both have that lower V8 NASCAR tone though. I love it!
