What diameter pipe fit in the resonator?

Never heard the pe in person but from YouTube it sounds louder than my setup. I'll try and get some vids up soon. In hindsight I would have wrapped both pipes and I still might.

Also the pipe wasn't welded in place yet in the pic.

Same question, what diameter pipe did you use to fabricate onto the existing piping? Also do you have any videos of how it sounds?

He built me a custom 3" stainless axleback with anti-drone chamber (like the afe) and dual 89mm tips. Deeper sound, less drone, and has a smoother, less raspy sound with the catless downpipe. (Plus it was free!)
