Hey guys, I didn't want my car stinking up the garage every time I needed to warm up so I opted for stock cats. Decided to go with 98 m3 cats (midpipes) with no modification and with a custom catback. Here's the results. I will try to get a newer video.
All in all I was happy and it was less than 1 bill with a helping friends hand. (DMS)
