Irs, LSD. same exhuast?

[orthaeeoul]

iv got a 04 S2 vy excutive with irs, would the cat back fit onto a mates car with an LSD?she has an 03 acclaim. (doesnt know what series)

[camstatic]

If they're both IRS it'll bolt up, provided it's the same engine. (Might even fit between engines but I'm not sure, haven't been there)

[orthaeeoul]

its an ecotec. im mostly curious if it will fit if she has LSD...

[SAV_117]

VT onwards every model had IRS.

LSD wouldnt make any difference. exhaust should bolt up fine.

Every model except the Tonners and a couple of other special ones. All sedan models had IRS

LSD is not significantly different (if at all) externally, so if it's going from a VY sedan to another VY sedan with the same motor I'd say you'll be fine.

If they are both sedans, yes it will fit.

If it's a series 1, then I believe it wont fit.. Worst case scenario is that it will need to be modified slightly..

[Not_An_Abba_Fan]

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.

[orthaeeoul]

cheers fellas, answer's all my questions.
Thanks!

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

-Nick.

[Not_An_Abba_Fan]

But it is a direct swap......

[savage1987]

lol....................

[nick_]

But it is a direct swap......

No it isn't.. I have a series 2 VY and I bought a catback to suit a series 1 and guess what, it was not a direct fit..

-Nick.

[Not_An_Abba_Fan]

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..

-Nick.

[Not_An_Abba_Fan]

The S1 aftermarket cat back exhaust?

[nick_]

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..

[Not_An_Abba_Fan]

Now I'm curious.....what did you have to modify to make it fit?

[nick_]

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..

-Nick.

[Not_An_Abba_Fan]

Is yours a sedan?

[orthaeeoul]

who u asking? mine is, hers is.

[Not_An_Abba_Fan]

Nah, was asking Nick actually.

But did yours fit her car alright?

[nick_]

Yeah it is a sedan..

-Nick.

[orthaeeoul]

cool... i havnt changed it after all... i was gonna buy a new system and sell her my old one. but just gonna buy a resonater instead...
