Didn't knew whether to post this in motorsport or the m50/m52 section, but i could use some advice on an exhaust setup.

I run a track dedicated e30 with an m52 and e36 m3 manifold (LHD car). The manifold is welded up to a standard e30 type 1 midsection and back box, but it hangs quite low and it is leaking a lot. So i am looking for a new setup that connects to the m3 manifold. What should i do?

It is a track only car, so no MOT issues regarding the cat. But don't know whether to decat or to use a race cat. Any decat experience with the m52? Also the question is if i should use a single pipe (2.5"?) or a dual pipe system. The car needs to pass noise regulations at Zandvoort, Zolder, Spa (92dB at 4500 rpm i believe), so cant be extremely loud.

Any advice? I live in the Netherlands and so does the car, so tips on local exhaust shops are kinda pointless.

Thanks in advance!
