that paints quite the picture. Im in a shared garage where I back into my spot against a wall for a quick getaway with the stock exhaust modded cold start, and that doubles up the volume I feel like... this may be an issue with the magnaflow as is haha. Wasn't necessarily looking for more volume, I just remember DPs on my e92 335 back in the day and they made a noticeable difference in the exhaust flow. I may have to hold off til I move to my own place in a few months, but regardless I'd have to think it would sounds pretty good with DPs.
