Default switched downpipes , now car studders

i have an evo 3 16g externally wg'd and tuned with fmic 750cc injectors , etc etc ..

yesterday i was putting one of my brackets on my up pipe to help it so it doesnt leak as much , it still does and it started leaking after my tune or who knows (thats when i noticed it) it doesnt scream cause its very small , but i went from a cobb turbo back to just now my cobb catback ebay downpipe which has more clearence for my ext wg so i left it on and it leaks at my midpipe a little bit

so i went to floor it today and it just studders around 14psi when my ext wg is about to open and i cant accelerate. i checked my wg line and all the boost lines and they are all connected. i have no idea what to think , but now im thinking about going back to stock sooner now

CN : changed downpipe , car studders during wot not allowing me to accel

EDIT : car no longer studders , but i found out my clutch is slipping

this might not be it , but did you re-use gaskets or put in all new ones when you swapped down pipes ?
