Anyway, just got test pipes on, and yes, it hisses a bit.

My buddy who did the install thinks it might be due to the fact the pipes are single walled, and that's just how they vibrate.

Note the big weights on the either bank of the exhaust around the Y-pipe -- this motor just has a lot of weird resonances to work around.

How long before you know for certain you're in the clear for getting a CEL? I've not driven too much yet, but have gone through multiple "trips".

Your not tuning exhaust pulses, just relieving back pressure, I don't' want to get into detail...wrong thread. I haven't heard anything about single walled pipes or weights on stock exhaust, that is kind of interesting.

As far as your CEL goes, you can get codes at any time....any time! Personally I wouldn't ever use steel wool, just seems like poor mechanics. Not that it is going to cause damage, but your just asking for problems down the road.

Get some high quality fittings and do it right the first time, you shouldn't have any problems with a high quality fitting for your O2 sensor. If that doesn't work the steel wool might....but your only buying yourself time and I guarantee that it will fail at the worst opportune time.
