Hey up peeps

Looking for a twin rear system for my gsi as mine has the diesel 1s put on for the mot and then sold

I have found a cat back system but it's off a 1.8 sri am I correct here
That the twin exhaust systems are all exactly the same

Depends on age of 1.8 sri, mines 57 plate (vvt) 40mm dia standard pipe,2.2 is 45mm, would thought gsi would 45mm or more. Now have full cat back powerflow system 50mm fitted.

It's off a 2003 mines a 2002

if dia is to small then it will restrict gas flow, check yours first at down pipe, what is dia off system you've found.
