Is there any way to get this exhaust's decibels down to 95 or lower without utterly destroying good flow characteristics for a wide powerband, maybe using some kind of internal baffles that can work miracles?
No more length can be added to what you see here, nor changes from the shape seen here,
nor a muffler added to the end.
However pipe diameter can be changed, and stepped diameters can be included in the length, if somehow this allows for miracle working internal baffling while keeping good flow characteristics across a wide powerband and limiting decibels to 95 tops.
What I'm dreaming of is an exhaust with this ultra shorty I'm-going-to-punch-you-in-your-face appearance and the performance to match...but without the I'm-a-Harley-pirate-pay-attention-to-me sound level.
