A cat back is not going to change boost numbers

If you get a tune make sure at the same time order the 3-bar map sensor,part#CX-2231,to aquire additional boost and performance,make sure to tell the tuning co,you want a 3-bar tune,here is the site https://www.rockauto.com/catalog/x,carcode,1446498,parttype,11207

Almost all of the custom exhausts people do end up with annoying drone.

Best to save your money and get a Corsa catback.....

Or just have them put in some sort of cross over or X-pipe.

It would help to tell them what you want instead of just assuming they know what you want.

It's a good show of support towards your tuner though!

I agree, I wont complain

When you get the 3-bar sensor first remove the old 2-bar sensor by the intake manifold and install your new 3-bar there,then make sure you have your new revised 3-bar,stat tune,easy peasy,heres a pic http://www.ecoboostperformanceforum.com/index.php?action=dlattach;topic=299.0;attach=6127;image
