Done plenty of research and have found that most series 2 vy's come with twin cat set up. My brother has a series 2 made in 04 with the single cat stock exhaust. Will a series 1 fit? If not why? Everything looks the same. Any feed back is muchly appreciated

Has anyone put a series 1 cat back exhaust on a series 2 that has a single cat set up?

If you swap the whole exhaust then it should fit straight up..

I've asked a few exhaust suppliers that say they've never come across vy s2 with single cat exhausts so that's no help. Has anyone put a series 1 cat back on a series 2?

managed to get a cheap 2nd hand 2.5" v6 vt cat back exhaust. It bolted straight on with no mods needed

i have a early series 2 and it came with a single cat exhaust but in 04 they went to the twin cat system because of emissions thats it
