Any tips/tricks for installing GTHaus valved exhaust?
 

Plan on doing the install Friday. I subscribed to https://www.youtube.com/@specONE Rodney and watched some of his install video, but I wanted different perspectives.

I assume that since this is built for the IS 500, everything is the correct fitment-wise, and the vacuum tubes/wire harness is the right length? I'm really curious on how people have everything run. Maybe it will be obvious once the car is on a lift.

I have two OEM exhaust gaskets and six torque solutions 12mm exhaust hangers. Is there anything else I need?

Can’t comment on the vacuum line as I have valveless but just a general installation tip. A portion of the midpipe was touching the sheet metal around the driveshaft. You may need to push the metal out of the way slightly to prevent rattling.
