The QG header is for a B11 swap GA16DE. The QG down pipe no is problem, I need modified the down pipe to adjust in my custom exhaust.
I decide this because the GA header in ebay is $200.00 with shipping and the QG18 is $120.00 with shipping to my country and i need modified the 2 down pipes any way. The most important is the QG18 primary header fit and this is not a problem . Thanks!
