For me and most of us enthusiasts, hearing the car is an extremely obvious and exciting way to enhance the driving experience. But, like I said in my previous post, I want the car to remain relatively OEM+ without doing anything too crazy and obnoxious. After a lot of research and hours on YouTube finding sound clips, I decided to go with the Strömung E30 325i specific catback exhaust. I read some good things on the R3V forums, but quickly realized the posts were years old. I reached out to the company and the owner, Scott, was extremely receptive and personally interacted with me. Though they didn't currently produce them at the time I bought mine, he got the BPs and made one for me anyways. The quality is second to none, finished in a super nicely crafted polished stainless steel construction, resonated exhaust tips, and some of the better welds I have seen on an exhaust system.
Quite honestly, its not as loud as I wish it was, and sometimes I feel dumb spending the $ to make it just a little louder...But, it looks much better, and is probably the equivalent of a modern day factory optioned 'M Sport Exhaust'. Again, OEM+ was my goal!
