g'day Dan,

amms/ roo systems quoted me, 3" mandrel exhaust mild steel $1000.00 fitted for my gu4.

a popular option is a scotts rod exhaust system, they are based at ipswitch, but you could buy one and fit it yourself at home, save some money...kinda thinking of this option myself actually.

are you just loving this rain!

Definitely buy a kit and install it yourself and the money you save put towards a boost gauge. Just becareful of the dreaded heat shield. It's a s$#t the first time you do it. Lol:evil:

Did mine not long ago with 2 3/4 and found it was a lot smoother through gears and more responsive. Exhaust gas temps lower aswell . Big big plus.

Thanks for the replies guys . What about power will it be a noticeable change

I just put a 3" system on my 2.8 and it made it so much better to drive, revs smoother, more torque, starts to pull from earlier in the rev range. went up from 8psi to 9. definately the best mod I have done. Mine was 800 including install. I would assume that this would all apply to the 3.0L aswell

I don’t know if you’ll get an answer, the last post was back in 2012!

I couldn't agree more, even then just a 3" exhaust is not enough to get the td42 to perform acceptably. Look at EGR block off, air box flow upgrades, and retune the pump to match and then you can actuall be in High 4, and let the clutch out in compromising situation like hill start and not stall on take off...!
