It usually goes away after a day or two of highway driving though.
How's the straight pipe for drone? Did you Tig the o2 fitting back on?

I had a shop do it because I didn't have a welder yet and he flared the ends of the pipe for me. He had a stack of sensor fittings and just mig welded one in. I got a borla glasspack behind it and theirs not any drone that I can hear over the tires.

Think I have my answer here fellas. Luckily I'm a metal fabricatior and can Tig it myself.

Thanks for all the positive feedback guys! Never seen a cat delete thread that didn't devolve in to a flame war. These are some great forums.

No problem. Incidentally, I also passed emissions with the pipe in there but your state may differ.
