NSW WTB mk3 CL rear muffler box

[Povi]

that is, assuming the exhaust piping on GLs and CLs is the same diameter?

CL is single 2.25" tip.
GL is twin 1.75" tip.
VR6 is twin 2.25" tip.

Spend $100 at your local exhuast place and get a new rear high flow muffler.

Or better still spend $250 for a 2" cat back sports system.

thats not what i meant,
the piping on the other side of the box, the side that fits onto the rest of the exhaust system...
