I'm glad my swap progress has been slow so I can be patient with this lol.
edit: I submitted an "order request" yesterday evening to Stromung and mentioned R3V. I have not heard back so I'm guessing they're waiting for someone to say the GB is official.Last edited by Zzyzx85; 01-14-2026, 11:14 AM.- '89 Alpineweiss 325i 4-door, 5-spd swap in progress

I’m IN on the “quieter Stromung SS cat-back system for the E30 cabriolet” dual wall exhaust tips for my 325i!
What’s the next step?
I replaced the rusted stock muffler with the IE cat-back (as seen on eBay ; )) which has great flow and NO DRONE, but my little inline 6 has lost some of it’s “German accent”.
I'm hoping the new Stromung design will be “just right.”

wonder if they would sell just the muffler with the pieces welded on so it fits the stock e30 hangers. I'm going 24v turbo, and the plan was to just hack up my OG group buy exhaust to work with the new engine, but I would rather just a brand new muffler instead of doing that1991 318is --- currently not road worthy
1991 318i ---- 308K - retired
