GT Black Series Exhaust Options
First thing I’ve seen published is the Opus downpipes … helps a lot but but I think a catback would help.

Right now the all exhaust packages they offer for the BS require ECU tuning because they are for cars with particulate filters.
I am discussing with him the possibly of making a no tune US version for cars without particulate filters.
Are we sure btw that US cars are built without PF?
If you decide to buy his exhaust package mabe he can put it in your BS stuck at the port so you can save shipping costs.

Do you know if your BS is on the water and headed this way?
I hope so.

"The result is astounding."




I had their high flow catless DPs and 200 cel cat relocation pipes on my F10 M5 and it was very nice setup.
