The racetube or de-silenced centre section is ideal aswell.....the more free flowing the better!

I just did mid silencer bypass done feels more freeflowing, going decat as well soon. Either 2.5" or pikey method of smashing a spare cat up.

With mid silencer by pass the agu back box and mid silencer is one piece, so be prepared to cut some pipe. Get a diesel piece they are around 15-20quid, its the same thing as race tube.
