I went for the cat back only on mine. Down pipes and connecting pipes add another £2k+ Sounds great and gets better every time I go out

Just Google Z3 remaps for your area, should be plenty about especially if you live in or near a big City. As it's a 97 model that means it's a single VANOS so will take the M50 manifold and increase your stable too.

I did a complete z3m front to back swap, including manifolds.
A lot of work and deffo not cheap.
Sounds awesome though.
