LSD and extractor Questions, VN Manual

[Mordred]

Hey there guys just looking at getting an LSD, extractors and a high flow cat for my 1990 series 2 VN commodore. It already has a 2.5 inch exhaust system so I was wondering the best way price wise to get the high flow and extractors on.

Also with the LSD which ones can go into my VN. as in newer model holdens? or Ford ones perhaps? and the best way to get a hold of them.

Thanks guys!

Put the extractors on yourself, same with the cat, little bit of stuffing around but it aint that hard.

a friend of mine mentioned having to weld the Cat, is that true?

Also does anyone know which LSD's are interchangeable with my car?

Why would you have to weld the cat...lol. Have you even been under your car and looked where it is or how it attaches? Bolt on jobby.

How much do you want to spend? I can do Pacemakers for $465, or Wildcat for $340. You won't need a hi flow cat. If there is nothing wrong with your cat, leave it there.

What size extractor pipes do you all have? 1 5/8" primary pipes 3" secondary? Is standard?

Surely you need a high flow cat? wouldn't a stock cat just bottle neck the system?

sounds good for the extractors but I'm in Victoria, I noticed your WA
