Someone posted a pic of a Boxster muffler cut open to display the baffling/routing. Does anyone have any additional pics?? I'm planning on modifying a Boxster muff ( ala 911 sport muff method) and I'll take any references I can get.

Also.........Someone posted a cool before/after pic of a 911 sport muff mod and I'll be damned if I see how a balanced flow is achieved for each header input. Am I missing something or does the baffling not matter because 90% of the flow just goes from the input pipe to the output pipe?

Horribly rendered thoughts (represented in red) on how to modify Boxster muff:

Cut off end pipes at inside bulkhead and weld up holes on outside, weld input pipes/flanges on front side, drill hole in each center bulkhead.

I have one of those Sport Mufflers for my 914/4 2.0

It was made from an OEM muffler just like a 911 or 914/6.
I got it from AJR many years ago and it was expensive but it
maybe one of the best, most fun parts I ever put on the car.

Loud? yea... maybe a little.
