Thank you for the feedback.
Was thinking basically the reverse of what you did: one resonator to two mufflers side by side.
Not finding the post, more important, not finding a video of the sound. These inline engines are unique and can't even find one for BMW except Magnaflows or mufflers for specific applications. Trying to avoid sounding like an American or Asian and express the uniqueness of an inline engine.
As an environmentalist living in a smoggy valley which has emissions testing, can't run without catalytic converters. The high flows are better than stock and with the larger pipe, flow better than stock even with stock resonator. If the resonators were instead high flows or none at all, certainly be even better. As I understand, you want
some restriction to keep the low end torque, though some better flow help with efficiency and temperature. In the end, not going building a high performance race vehical, just a little more sound, but less than running without a rear muffler as now.
B.T.W., did once for grins run no pipes, just the headers, and wasn't all that loud, reminded me of an inline aircraft engine. Though not sure the neighbors appreciate it at dawn
As I understand, the 280SL M110 had a dual in, dual out, stock unlike the W123 European that seems from what little can find was a dual in, single out. Right now I have the former and love that it's a better design and who doesn't like two pipes?
Speaking of pipes, plan to extend them a little more so hopefully the exhaust doesn't get into the fog lamp like stock since those are a pain to get here in the States. Leaning towards pea shooters so obvious that have something special and keeping with a SL thought.
