Finally a day without snow or rain, in fact it was a balmy 54° today. So I was able to shoot these today.
I drilled ¾" holes on each side and it is not excessively loud at all. Just a nice throaty growl to complement the perma-grin.

Woo-Hoo thanks all, this mod works great!! It took me about 15 minutes to drive to the hardware store and about 2 minutes to drill the holes. My Boxster has a much deeper sound at idle and up to about 3000 rpm. I have a 1999 Boxster with the single outlet all I did is drill slowly and hold the bit so it was firm up against the outlet. Drilled one 1/2 inch hole in each pipe and with the angle I suppose I ended up with a 3/4 inch hole in each. Thanks for saving me the $350.00 I was going to buy a %is&#& after market bypass this does the same thing.

Can anyone post pic's with the welded Oval tip exhaust? I have a 2000 986 with the single oval tip and was thinking about doing this mod. Is it any harder without being able to remove the exhaust tip? Should I angle it a little more?
