Headers always look nice and the SS ones sure do look good.
A few things. measure out the runner lengths. you don’t want the front runner and the back runner to be off measurement wise more then 1" other wise there actually not going to be doing much to help.
The look like they have a nice sweep so that should help.
what is the size that they open up to after the Vband
I would measure the gasket size and then the port size of the stock and the headers. Also take your exhaust manifold gasket and mount it up to the headers. This will let you know if the ports are all on center. The china B5 S4 Turbo headers were always off. I don’t think your going to have any issues but its good to check.
I like the Vbands as well.
It all looks great. when is the motor build going to start.
