Test Pipe (cat delete) and vacuum lines for E36 M3

Hey guys, so my M3 is pretty modded out, Dinan S2, Schrick Cams, Stage 2 Vanos, Dinan Catback, Shark Programmer, big injectors, big throttle body, M50 intake etc and so-on. My car recently had a miss, which we've potentially diagnosed as a vacuum leak from one of the six vacuum lines under the intake manifold or potentially from the intake elbow. I'm ordering a silicone elbow from Turner, but don't know where to find the proper vacuum lines for our cars. Any ideas?

Also, while I'm in there, I ordered an Ebay header, which I'm going to have inspected and coated prior to install, but my issue is, I can't seem to find a good cat-delete (test pipe) for my car, other than the $700+ ones from Turner. Any other ideas? I'll also need an o2 sim, if you have any good leads on those, it'd be greatly appreciated.

Thanks.

Just realize that running a cat delete on a street car in the US is a criminal offense. Fine and possible jail time.

And high flow cats give as much power, without the issues.
