If your running a bolt-on jap exhaust, then yes it most likely should being the dimensions will be the same.

Its only those running AUS custom ones that i'd say it wont fit on.

Flanges will be the same, i wouldnt even worry about that, they will be two bolt like every other 3" exhaust flange is.

depends on the car, the tune and how open/straight your exhaust is. Mine did it with the cannon. Dunno if it does it still with the big rear muffler installed.

A mates sil80 with nothing but a cannon won't do it, same with his s13 race car with no mufflers.

3 to 1, i think the will fit has it won there :D

make that 4-1

i just changed my turbo and put a jjr 1 piece split dump on and it lined up perfectly, whilst i was there i took note of the cat and the flanges look the same as the one pictured so im guessing there 3" high flow cat will be a straight bolt on as well.

i dont know who did my exhaust but it had the factory cast front dump then a 3" pacemaker dump into a factory 2.5" cat and then 3" after that.

Definately a NO NO... There seems to be massive fines (search for other de-cat threads)...

But you'll get performance gains... Just have to weigh up what you want and how much your willing to pay for it...

You bets your money, you takes your chances...

just get a hi flow cat, there are plenty of great hi flowing cats now available as technology advances. the fine is just not worth it when you do not pass epa, etc. besides, now you have to tuck away your oxygen sensor since the de-cats, from what i see, do not have provisions for it? someone correct me?

      What should I do next to hold the head on

      Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.

      Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.

      Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
