I took the SLR to Toms Mufflers on the Stuart Hwy (Darwin) today and can actually say they did what i wanted, and did a good job.
I got them to fit 2 1/2 dual system.
I got them fit 2 bolt flanges after the tranny so i can go racing without cooking the turbo 400.
They fitted my x pipe i purchased from evil bay.
They supplied and fitted 2x offset in, center out Supercat straight through mufflers with 2 bolt flanges at the back of them.
They fitted my old tail(dump) pipes.
All good welds, no leaks, no nasty bends and the pipes clear the tranny really well like i asked them to.
The sound is quiet and tuned.
