Shane thats tractive effort not torque .your torque is more like 385nm stock .
a 2j making 874 rwhp makes about 1066 nm of torque
1100 nm of torque would be around 950 h.p
The twin pipes alone are not the answer .To get the full result .you need to use twin 3 inch cats an x pipe and prefferably 3.5 inch final pipe
Any Good exhaust shop can make them .
i originaly designed them and Joey had them made on the Central coast.The designed has Evolved Several times since then
i originally had brendon make my first ( and his) set .But have since had them modfified with excellent results
Peter from Newcastle Exhaust has done the best job IVE ever seen
and mid range torque was greatly improved .
By reversing the bends from the pic above the front turbo pipe (on left)now goes almost straight down AWAY from the Engine and the rear turbo.bends outwards and down .
ALSO If you can go slightly larger than the pipe in the picture and eliminate the bottom bend (not needed).
If you do get Brendons i recommend having them Interanlly ground with a die grinder .removing the UN-even welds and reversing the bends gave me about 10 kw more and dropped 0-100 times by 0.3 sec
