It will fit regardless.

The series one had a single cat, the series 2 had twin cats, but they had a y pipe that brought the front flange of the exhaust to the same place anyway.

Just didn't want to get their hopes up by saying it'll be a direct swap..

The stock system is a direct swap.

You must have removed the Y piece off the cats from yours did you?

Nope..

I went one better and upgraded it all.. From the heads to the muffler tip..

Now its a twin cat setup designed for a L67 but with a single 2.5" catback..

But that was after the S1 exhaust wouldn't fit up to my otherwise 100% standard series 2 exhaust..

Yep. Was advertised as a direct fit for all VT-VY ecotecs.. I don't think it would be different in terms of length compared to a standard s1 exhaust..

If I was going to stick with it, I would've had to cut off the flange (from the catback) that joins up to the S2 Y piece and add in another say 2-3" give or take of pipe and weld on the flange..
