Following on from Rayner's questions about exhausts for a Z20LET, I was wondering what's available for the 2.0 XEV (N/A)?
I've just had a look at Courtney's site and they only seem to supplu zorts for turbo Astras, so where's the best place to look at?
I'm after a zorst system first before I go ahead with any planned remaps as this seems like the most sensible option, so i'm not bothered about noise, just power! What's the best in terms of replacment cat? For example, the difference between a pre-cat and sports cat? What can I get for XEV that's MOT legal but sitll improves peformance?
