New LS1 Owners - Newbie Tech - what do you think about this setup?

later this month im getting a 2000 Z28 A4, very low miles and im getting rid of my 83 z28..
for exhaust i plan on getting Pacesetter LTs, TSP 3" cat y-pipe, and hooker 3" aero chamber cat back....and for induction K&N filter with a GMS lid.
thats all i really plan on doing to my car other then tires when needed and once i get more money a cam....what do you think about that set up? and what kind of gains do you think i would get from stock?

I had an a4 z for a while, I would say you would add 25 hp or so and 15-20 torque wise. Sounds like a good setup, although I am a corsa exhaust person myself

thanks for your imput i was hoping to hear larger numbers :'( is there a better cat-back that would give better power gains?

honestly they are about the same, just depends on the sound you want. You may very well put down better #'s, I just didn't want to get your hopes up.

You consider a true dual setup? with an X or maybe even an H pipe?

no not really since i would much rather just get a system that goes out the back..and arent true duals more expensive?

should this set up hook up fairly easy?im actually about to buy this tommorow from Texas-speed i think..
