VXR Exhaust onto SRi??

**Casper85** · 21st August 2019, 06:11

Morning guys,

Haven't been on here for a while, no thanks to boring adult life & working too many hours!

Anyways, I'm in the middle of a project to convert my Vectra SRi 2.2direct into a VXR replica and have a query regarding the exhaust system of the VXR...

I have managed to source a good 2nd hand cat-back system off a breaking VXR and was wondering what size reducer pipe I would need in order for it to fit onto my 2.2 exhaust or will it be a simple straight swap??

Any advice, as always, greatly appreciated :-)

A simple tool called a "Vernier caliper" will actually measure the outer diameter of the pipe on the car and you can use the same tool to measure the outer diameter of the pipe you got of the vxr.....

Or a tape measure and PI

I fitted a full vxr system cat back to my 2007 2.0t Sri... Not sure if same exhaust but my standard is 55mm and the VXR 65mm. Bought a reducer from MIJ direct... Exhaust was relatively easy to fit on the driveway..
