Turner Test pipe Questions!

Hey guys i was planning on going down the boost route but i only have an axleback exhaust wise.. i was told i would want full exhaust or the cats cut atleast to get maximum power. At the moment i have a Rpi GTM axleback but the full gtm was loud... my buddies gave me options of selling and buying a new exhaust or investing into turner test pipes i would really love some input. I have done research on all this looked for videos but cant really find to much also would the gains not be as much as a full x pipe? and does the turner pipe only cut primary or both sets of cats ? Thanks for all the advice!
