Stromung cat back Group Purchase

Should we proactively get a list started so we can get to 10 buyers confirmed once Scott at Stromung is ready to produce? -
MAybewonder 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 that

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.”

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.[/QUOTE]
Scott has yet to complete the prototype "quieter" system.Leave a comment:

I'm glad my swap progress has been slow so I can be patient with this lol.

It'll be swell if I know that the 89mm 318i exhaust could fit the M10 without issues, Although I will be ordering very soon so I wonder if I need to include the "Group Buy" In the message request?Leave a comment:
