What frontpipes are you guys running and how bad is the noise and fumes?
I'm think of getting the Blitz 2.75" catless front pipe, so anyone have this and would gains be big? I have mine tuned to 12psi max.

I ran a Sydney Motorsport Engineering kit with a Borg Warner turbo at 18 PSI tuned by Delicious Tuning utilising the stock front pipe. I had an SME over pipe and a stock midpipe with only an axleback exhaust.
The main issue I found was boost taper. 18 PSI used to taper to 12 PSI by redline. I swapped it out for the Blitz 2.75" and put the stock axleback muffler on and found my issue mostly resolved!
You have a lot of different piping sizes in your exhaust so it would make sense to bolt up a Blitz front pipe or similar, even if just to cure my OCD.
