Another happy camper! Thanks crios!!

I did the drill mod on my 2003 Boxster and ended up using a 7/8" drill bit as final hole size. I did not have a 1/2" for my heavy drill. Worked as desired with a nice low growl at low RPM"s but no noticeable droning or noise increase at cruise RPM with the top up. I did have to use a cold chisel to start the hole for the drilling and had to step up drill size to make the final hole.

Changed exhaust tips to the two round S type to go with the new sound.

Great Mod!!
