[Sydney111s]

the varex is not a cut out- its a dual circuit muffler-watch the u tube clip for the VE commodore (4 door version of pontiac GTO).

I used the:
Single Tip Oval VAREX:

Inlet Size:3";
Barrel Size: 6"X10";
Tip Size: 4" or 4.5" Round Double wall tip ( I cut this off, and connected a tail pipe, that eventually leads to twin tips in stock location)

Have done 4000km on this exhaust with no CEL/MIL- car has been great.
