A cat back is not going to change boost numbers

Not looking for boost increase with exhaust JUST DONT LIKE SOUND OF IT TO LOUAD AND TO MUCH DROWN

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.

I agree, I wont complain . I will get the plugs from him as well since I got the BAP and t-stat already.

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
