Rule 1

I didn't see any dyno charts on the ebay store. Maybe I just missed it? It did say their opinion was 10-15 HP gain, but who knows really...

Did you go with the Maxspeed exhaust also? I have a B&B and like it so far.

Do you have the chart you can post along with sound clips, etc? I'd love to hear the sound difference.

I'm wondering if you can extend the O2 sensors that were in the cats and have 4 O2 sensors after the secondary cats thereby tricking the O2 sensors not to throw a code?

I will update if I get anything from my local mechanic.
