sales@amsmotorsports.com -not being facetious but I reckon if you shoot them an email they’ll let you know pretty quick. Also with the $AUD in the toilet now might be a good time to shop local
cheers might do that. Well aware about the AMS products and business practices, how can you not searching setups and parts the hole community is spammed with it haha. just thought somebody might know in passing, I can stomach 94c in the dollar Canandian but not 70c US plus Gst on goods and freight. Chinese parts become pretty expensive. Really just want a 4 bolt dump and front pipe combo in 3" that bolts to a off the shelf cat back. Local would be Npower dumps and front pipes and I see Npower dont list the front pipes any more and there what 2.25" By the way it appears Skyline and S series after market cats would bolt up to Your dumps Rob that gets it closer.
Any aftermarket barrel type cats would fit as the dumps just terminate with a 2 bolt flange (or v band if needed). You would need to fabricate from the dumps to your cat back, or fabricate a new system from dumps back depending on what you’re doing. I just did one (well supplied parts for one) using my 4 bolt split dumps and then magnaflow cats, x muffler, and rear mufflers. Came up quite well and not horrendously priced. I haven’t really pursued getting front pipes made as by the time you’re running a 3” dump it won’t be bolting up to the stock system anyways.
