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

Cost was £700+ then fitting costs. I have a K&N57i Induction Unit also, defo a difference but not massive but just sounds and looks the nuts :D

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.

Please advice me guyz from your end. Thanks. .......
 
2.5 Inlet manifold, 67mm throttle body, USA z3m cams, s50b32 exhaust manifolds, and cats and back boxes, remap =245-250 bhp
