Hey HT, so I just got my B18c (GSR) from HMO and i am planning to put in it my 00 Civic Si.

But i have no idea how the puzzle of these exhausts go together. Ill just list what i have now.

Stock Exhaust Mani (b16)
Stock Cat (b16)
Apexi cat back system 2.5 inch

Now, for this b18c, I am getting a ITR Toda 4-2-1 (2.5 inch collector) header, Now comes the missing puzzle piece. .... the test pipe ( or cat... what ever)

What kind or size do i get? it should be 2.5 inches on both sides. but i don't know what length or angle the flange is at,...

I was thinking I might as well get a adjustable test pipe, but then I wonder if i get that, does it only adjust is segments? as I take away sections of the test pipe it gets smaller? IE (either 17 inch or 12 inch)

Any information is better than what i know now.. So thanks in advance.
