Hi all , can anyone with access to a TXS evo exhaust please measure the length and outside diameter please . Should be 14 to 16" long and either 4 or 4 1/2" OD . I just want to know whether or not they're using the 3 1/2" ID (4 1/2 OD) resonator in a 3" pipe and if that helps make these system quiet .

Cheers , A .
