Sorry to ask so many questions, but my 964 has stalled on a few occassions, but I am pretty bugged out by the new old car because of all the mods. Today it bogged down in when I was cruising at a low speed in 4th gear. I had to shift it to second and it kind of stumbled and came back on while rolling at about 40 mph. I am just curious as to whether the different back pressue could cause problems in idling or the engine. Should I run it at all with the hole that is about 5 inchs by 3 or 4 inches. Right now it is just loud.

Dear Doug,
Please change the muffler. Yes this will cause all kinds of running problems as well as being potentially dangerous to your health.
