Stromung cat back Group Purchase

[Stan]

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.
