Just after some recommendations on exhausts etc.
Atm i have standard headers, and goes onto 3" mid section to the muffler. Nice rumble but needs an upgrade now....
Should i just change the mid section with a new muffler etc, or should i get larger dump pipes aswell?
Any help would be greatly appreciated.

I don't reckon the primary turbo is big enough to warrant a 3" dump dude.

i was saying 2'5 max on primery. 3 inch on secondary...anything bigger on primery causes over spool. but you be right in saying that Soop

Oh yeah, I misread.
Even still, are either turbo big enough to warrant a 3" dump?
I mean, blokes get away with 3" dumps of turbo's 4x the size.

I have 2.5inch off both turbos, then 3inch back into a magnaflow. Sounds really nice, and not too loud.
I should just convert to single, right?As soon as she hands it to you, slowly take of your pants, then, while staring her straight in the eyes rub it against the tip of you penis, while continuing your painfully intense gaze whisper to her;

Yeh sounds like a good idea with the magnaflow and 2.5 on both dumps into 3...
I had a magnaflow on an old lancer and that was really loud.... Dont want it to be too loud...

Good. As pretty as SS looks, I could not justify the cost!
