what he said go to any exh shop they will ahve some flanges and a piece of pipe, sorted.

do remember if epa catch you 10K fine tho ;)

only use it for the track if youre worried.

putting a cat in for street use it only going to make it rich.. and only by a small margin if that.

Going to order a 3inch, high flow 5inch body venom cat. But its about a 4 week wait.

Just thought of using something temporarily for the dyno.

MIght just ask trent to tune it with the exhaust dropped from the cat onwards

Don't they have mobile EPA stations these days that randomly pop up these days?

Not sure if its worth the $10k fine..

like any cat that 15 years old is fully functional anyhow.

but the idea of the straight pipe in a cat body is the best one. know a few who have done it looks perfect and great performance.

I thought you only got that if you ran rich,

no cat and it tuned correctly I've seen many with no soot.

Yep, you get soot when you're basically pissing fuel all over.

    • 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)
