Well, it's been a few months now since this thread started, so time for an update? Has anyone experienced problems as a result of this? Has anyone ran a/f ratio readings since the install? I've noticed that my car only does it sometimes, usually when the temperature outside is in the mid 40's. Sounds crazy, but I've only had this problem for a couple of weeks in the spring, and then a couple of weeks in the fall. Now we're having mild weather in Atlanta, and it's back again this week.
Getting fed up, plus it's embarrassing pulling up to a stop light with an exhaust that already gets attention and my engine's at a steady 1,200 RPM idle in neutral, not too mention I practically have to ride the brake to avoid rear-ending the car in front of me!
Just a little frustrated, so any new input would be appreciated, otherwise, I'll probably do the mod this weekend.
