OT here but are you going forward with the forged pistons or are you working on something else?
Cat back exhaust is UUC TSE3.

Installing forged pistons and better sealing rings that will stand up to 8 lbs FI better - too much blow-by.

These header/cats LOOK like they will install pretty much the same as OEM but there is always a doubt (for the first time anyway) that there will be clearance problems. Just a little concerned.
