Extractors for 2L Escort

[Pazuzu]

Hi all.

I'm investigating extractors for a stock- standard 2L pinto motor on my mk. 2 esky, just for a touch more power & better sound. Probably looking at getting a new exhaust system fitted at the same time. Can anyone recommend a business in the Brisbane area to contact? Don't want to waste time with stooges, would rather get the info first- hand from people who have had this work done and are happy with the result.

Any help is greatly appreciated.
