Gt3 cat replacements

[NIgt3]

My 97gt3 needs its Cats replaced, I'm running with a fvd muffler bypass and was wondering does anyone know of upgraded cats can be used are do I have to replace with the standard cats? I was reading a topic on rennlist about side muffler delete pipes but was told by the vendor that these will not fit with my centre bypass and also will be waking the dead loud when combined with it, any addvice appreciated!!

Have a chat with Matt at Fearnsport, he'll get them rebuilt with the cats of your choice.

Also speak to Gert at Carnewal in Belgium....he can also apparently get them rebuilt & has a very good reputation amongst the Porsche community
