Would the exhaust on the Jap STi SG Foz with a 2L be any bigger or better than the exhaust on the Aussie SG Foz XT with a 2.5L?

Not looking to use it as an upgrade over a decent aftermarket one or anything.
Just curious as to whether it got a better dump pipe or a larger diameter, would the centre section of the exhaust be any bigger on the JDM STi SG Foz than our AUDM SG Foz XT?



Cheers guys

I think the headers on the STi ones have better/bigger pipes but get a proper dump pipe with or without the splitter for sure. She'll spin up alot quicker than stock

There is no such thing as a 2L SG STi. All SG STi's were SG9's, making them 2.5L.

That said, there isn't much difference between a SG XT exhaust and a GD STi exhaust upstream of the diff section.

Well I feel like an idiot haha dunno where I read that, probably on a yank forum. Am still gradually learning Foresters...

Honestly what I've been considering is a stock-looking upgraded exhaust consisting of JDM v10 STi Spec C dump-pipe (proper bell-mouth style), whatever the biggest Forester centre section I can get is and the Forester-specific STi "Sports Part" oval muffler. Want to do the JDM v10 STi Spec C twin scroll manifold and up-pipe with a VF36

A twin scroll conversion on a MY06 XT is not a bolt on affair...
Check out this build thread: Magus' MY06 XT
As for an SG9 JDM STi exhaust, same as an XT with a prettier STi tail pipe but a restrictive muffler.
For an XT, go aftermarket 3" with a turbo upgrade for good gains.

To be honest, i dont think the advantages of TS are really as big these days as the were at the time. When compared to the turbos getting around today, a properly sized turbo with modern billet wheel aero and quality ball bearing core will be just as responsive and even more powerfull, and save dramas with TS plumbing.

When TS turbos were put on OEM cars nearly 2 decades ago, turbos themselves werent as advanced and capable as what we have available on the market now. Hence why they were looking at using TS technology and such to improve things in the first place.

As bram said, i'd go with a better turbo. Billet wheel and dual ball bearing chra, ATP do a bolt in one.
