Not a B but a C..
I have a TTi 2-1/2" system on my car.
It is bolt on and go.
The only exception was to drill a couple holes in the rear shock cross member for the second muffler bracket,and cut away on the other side a wee bit.
The flanges are really nice and thick.
I am really pleased with their product.
Well engineered.Nice fit and does not hang down.
I installed it in 2006 and the aluminized finish is still like new.
