I didnt weld this myself, had a buddy who owns vettesandperformance.com do it for me. My tig welder is jacked up and isnt putting any power out right now. I can do small stuff like exhaust..but not this and feel comfortable with this. He does amazing work. He did the vband turbo flange, wideband bungs and npt on the collector.

Individual cylinder trimming, I'm running full sequencial spark and fuel. This will help me tune for more consistant cylinder to cylinder afr. I didnt do it for this reason, but I heard some honda n/a guys getting 10-15whp more on 200+ whp cars..doing before and after individaul cylinder tuning.
