Default Exhaust system design for Legacy TT engine?

I have free rein over the exhaust system for this engine in the project so, do I need to run both pipes into one or can I run 2 seperate systems and also as I don't have any cats, I have heard that running without them can cause boost spikes on the primary turbo.. any ideas on how to prevent this?

Cheers.

Anyone?

I had planned on using a couple of Porsche 996 (911) silencers as they're fairly compact, flow up to 360bhp (the pair together) and have 2 inch bore pipes throughout. I've not measured the stock downpipes from the turbos but I'd expect they'll be a similar size.

When removing the dash to get the loom out, I stumbled over this!





Obviously some has been fiddling! maybe this would help with the boost spikes?

Has anyone here used a Fuzzy Boost Controller? Any views on how well they work etc?

Thanks
