So, for 930 (9dreizig), I don't have a great pic, but here goes anyway. Sorry, I am new at this.
Jackb911, I appreciate your offer. I am going to run it on the weekend without the muffler (pre-muffler only) to see how that sounds. For special occasions I may keep the pre- and stick a tail pipe on it. If that's the case, I am interested in your test pipe. If that's too much I will let you know, and we can work a swap.
Thanks a lot.
