Update! I ordered a B46 Catless DP from EuroMotive Performance out of FL and installed it last week. I plan on keeping my stock DP incase I need to change back. It looks very similar to the ER downpipe at a VRSF price tag. I happened to order their very last one in stock. They don't have a lot of reviews for the G30 so I really took a risk.
Finish looks great, and I would give it a 9/10.
Fitment was kind of hard. It took me about 2 hours to install and the mounts were off by an inch, so I was not able to mount it to the stock mounts on the car. However the DP is mounted on both the engine and midpipe very tight along with a new gasket, so no issues there. So far, no real detectable gas smell and sound is amazing, a little drone at lower RPMs but that is to be expected. Because of all the wrestling I had to do to get it to fit, I would give fitment a 6/10.
Now I flashed to Stage 2 on 93 and the car is much more fun to drive, with about 20-21PSI max from my tune. All issues aside, installing a DP on the G30 was a breeze compared to my previous F10 550i. Cheers!
