hi there
looking at upgrading my exhaust
is it worth the extra hassle to change/fab a new bend right off the turbo or will I still get decent gains if I just renew it from the down pipe onwards
cheers

half your money and 10% of the gains are in that front pipe. If you want the ultimate do it but I wouldnt bother unless it has to be changed

I'm yet to understand why. The time to make a dump pipe vs making the rest of the exhaust is crazy.
It took me around an hour to have the dump pipe made. vs a whole day to make the rest of the exhaust.

plus that flexi joint etc.
Exhaust shops increase prices on stuff they dont want to do

I have just recently upgraded the whole system in my Mu (4jb1-t) and the results take the sting out of the cost!
If you go down the same road as me it cost $1200 for the exhaust - excluding the dump pipe. Dump pipe came from Australia at around the $200 mark... I removed the old system also to save some time on labour.
With that done it gives a nice sound but no major increase in power- that comes later with extra boost and fuel!
Once its all said and done I personally think its worth it- Ive only got a max Egt of 400dg with 1full turn of the fuel screw
And it has a heap more power. So room for more yet.

I did this. Its loud. There isn't enough space to get a muffler or anything of decent size to quieten it down until you get to around there the rear wheel is.
^^Assuming you mean in front of the rear wheel not behind.
