OK, so after a few interested parties contacted me I am going to use this thread to track interest in a Group Buy on the Stromung catback exhaust for the e30 M42..
At this point, I have had a discussion with Stromung and I have requested a breakdown on price etc. from them depending on how much interest is generated. The last Group Buy for these ended at $399, so I would hope we can at least get close to that number.
Just to be clear, there is nothing in this for me other than convincing Stromung to make another batch of these. No payments would go through me but directly through the manufacturer and I am not getting any kickback, just the same better price I can hopefully get from them for doing this.
One last thing, it is my understanding that Stromung will only make another batch of these if we get enough interest, so while this system (pictured below) is listed on their website at $469, I don't believe you will actually be able to buy one at all unless we get enough interest here. I will also post this over at M42club as well under the same username.
I have personally inspected one of these on another members car, the fit and finish is great and they sound fantastic. Not raspy, a nice deep sound very befitting of the car it goes on..
Please either PM me or take the list below and add your name to the list.
Here is the catback, it has an 89mm (3.5") stainless 304 tip and is a straight bolt on. I believe the main piping is the same size as stock but this isn't where the restriction is anyway on these systems. These are hand made..

Final GB pricing is $439 for the complete catback system. Remember, this system is only made to order so if there are any more of you out there in need of a quality catback for the M42, this is your only chance for who knows how long. The only other system for these cars that is IMHO not as good as this setup is well north of $600!!
