In chatting with ECS, they mentioned its fairly quiet, just about louder than OE.

Which, IMO, I do like, but I know I am a black sheep in that regard.

The mufflers need to be straight thru with 2.5 inch perforated core. No chambers no bends
Just a perforated core and some packing material.
Avoid bends like the plague.
For quieter systems use dual mufflers that are 40cm long
,less length> sound

I would be interested in a resonated 2.5" section 2 w/ no crossover and a section 3 with similar characteristics to the scza in that it's quiet at idle and normal cruising and doesn't drone but really opens up when you get on it. Hopefully lighter and would prefer slant cut double wall polished 83mm tips. That would be my perfect setup.

I guess they make an exhaust for the S54 already on the Z4M. Here are some videos. So far I haven't seen any of their exhausts with slash cut tips though.

Default Re: Help me bring a new exhaust to market

Alright, so I am going to pass on this preliminary wishlist:

Must haves
  • 2.5 inch piping from header back - I need to dig deeper and see how we can make this compatible with OEM sized connecters - stay tuned for an update on this one
  • 0 drone
  • Resonated mid-pipes
  • Shed weight

Wants:
  • Two muffler options - 1 more civil dual-duty system and a high performance screamer
  • Multiple tip options - both in color and design (slant cut vs dual wall)
  • Optional crossover in/near the OEM location in the section 2

Once I hear back, I will let everyone know what is feasible and we can go from there in terms of design/sound/pricing.

I think you most of it! Maybe incoroaprte what Hassan said about minimal bends for the muffler. Maybe something similar to the SS Race design and the one Hassan made custom for himself.

Stromung consistently makes awesome stuff for other platforms! I'm excited to see where this ends ups.

No need for a difference in performance between the civil and loud mufflers! E.g. SS street performs 100% identically to SS Sport performs 100% identically to SS Race.

If you're going to focus on optimizing a muffler around higher flowing headers/1/2, I'd target SS Street/stock levels of volume. The SS Sport is nice with stock everything else, but it's pretty loud once everything else is flowing freely.

That is 100% accurate. Performance and sound levels are not linked to an acceptable degree. If the muffler uses absorption(straight perforated core /tube with packing material ) performance won't be affected at all, like this :http://www.m3forum.net/m3forum/attac...8&d=1487101083 If there are sound barriers, deflectors and restrictors/chambers, then forget about it, there certainly will be power losses. Also see video below, although it says cheap vs expensive, the real argument is about design and how sound is absorbed rather than restricted and deflected/reflected restricting flow in the process:

I loved my Stromung on my old e36. It sounded great AND was one of the LIGHTEST exhausts for the car.

Weight would be a major selling point for me. Sub 30lbs for section 3 at a minimum and less if possible. That might be geared more toward the "race" version.

I'd prefer a single exit over quad but am probably in the minority on that one.

If its light and sounds good I'd buy in a heartbeat regardless of price. Save myself from hunting down a Dixis and paying top dollar.
