Hi, im from the Sydney area would anyone know where to buy and fit
- Berklee BS0655
- 90mm intake
- extractors

Or anything else that would improve my performance (not too expensive) ?

RPW sell extractors. Speak to an exhaust shop, get them to supply-fit the Berklee muffler, and fit the RPW extractors for you.

The 90mm intake is available from eBay USA, and you can fit it yourself.

There is a local Oz seller who me and a few others have gotten the 90mm intake from, see here:

Mitsubishi 380 high flow air intake snorkel galant (http://www.ebay.com.au/itm/Mitsubishi-380-high-flow-air-intake-snorkel-galant-/150929709631?pt=AU_Car_Parts_Accessories&hash=item23241c9a3f)

A bit cheaper than the US seller (rockauto). Edit - whoops, I meant RCHill, see here: 08 09 MITSUBISHI GALANT 380 INTAKE BOX & SNORKEL (http://www.ebay.com.au/itm/08-09-MITSUBISHI-GALANT-380-INTAKE-BOX-SNORKEL-/390108685805?pt=Motors_Car_Truck_Parts_Accessories&hash=item5ad44a25ed)

You need to carve out the larger opening in your stock air box, but easy to do and plenty of threads here on it.

Does that place in sydney still do the headers?

I got my Berklee fitted at Liverpool Exhaust for around the $300 mark which included widening the flange also.

Okay thanks a lot for the information I'm new at this. I was thinking of heading down to liverpool exhaust, what muffler would you guys recommend for the 380, if you could give a variety ? Thanks.

Supercharger is the only sure fire performance mod for the 380.

Sprintex sell them?

Sprintex no longer sell 380 SC's. They will make more if you can get a group buy happening I do believe

Correct, we require about 20 interested parties to get sprintex to manufacture a batch.

I disagree, extractors / replace cat gains alot.
