3" from the turbo back for the best results, a 3" cat back is purely for noise not performance.

cheers thats what i was after just making sure i wasnt going to loose power with a stock turbo with the 3 inch

For now install a cat back system and a metal cat leave the dump and front pipe.

When i installed my ATR43G3 the stock front pipe didn't quite line up correctly meaning i had to get one custom made. Might save you a fe $$$ waiting till your turbo has been installed

Looks like you will have to go all custom. Get a dump and front pipe made seperatly. That way you only need to get the dump remade.

Better option would be to go the turbo now as you will save a few $100 remaking the dump

yeah i wont need to change the dump because i will just use the sandard rb25 dump and get it made to suit my mate makes exhaust so money not really a issue and i dont know how long until i get a new turbo

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
