Invidia Q300 Catback installed 2021 ILX

9th Gen Civic Si Invidia Q300 catback. Bolts up fine. A 98% match for the ILX but the shop had to heat the pipe before the muffler and pull at the tip to get the exhaust tip perfectly on center (the tip was pulling towards drivers side and rubbing the valence). I had an idea something like this would be the case- this is why I didn’t bolt it up myself.

Sounds great. Throaty and performance sounding with some pops when letting off the gas. Not loud or annoying. No drone.
