Stromung cat back Group Purchase

[Stan]

Any guesses as to the timing of this group buy? Estimated month items might ship? Don’t need a commitment from Stromung, just typical timeframe based on earlier group buys would be helpful.

typically once he gets the raw materials, it is pretty quick. The supplier of the pipes went through a change of ownership and once fully resolved the production should be soon. Also, he need t confirm pricing on his new stock before committing to a selling price. It will be discounted due to volume. Frankly he is amazed at the attention! They thought E30 interest was done so they tossed the jig and needed to make a new one after we started the group buys!

Can I get added to this list? 325i angled double walled If available, If not, then whatever they'll offer for the group works for me.

Once I hear about pricing I will update ya'll on my buy/not-buy...but probably it's a yes.



If possible can you ask for details on the new quieter design? Mainly I am wondering if it sacrafices flow (aka how did they quiet it down).

Scot was telling me it will be a redesign of the muffler itself and should not impact performance.

Did I get skipped, I'm interested unless there's only 10 spots.

Edit. I misread that part, my apologies. If a spot opens up, let me know, thanks!

My bad. I did skip you lol. I don't think there's a max limit, only a minimum for discount amounts. The more the merrier (and better the discount!)

Definitely not overstepping. I plan to speak with Scott today (2/10/26). This is a team effort.

Amazing to see but I already bought my exhaust from scott back in November of 2025! Please give my position to someone else who can help in the efforts of this thread! Thanks!

I got a few responses on FB and pricing came up most of the time. Hopefully I'm not overstepping Stan but I went ahead and sent an email to Stromung (Scott) to ask about pricing.

I'm interested for a 325i. Pricing would be great, I know it's pending!
