exhaust q's

[stmotorsports]

Hey all. I have a '94 civic EX coupe and it needs exhaust bad. I know a guy that will let me have his stock GSR system for pretty much nothing till I can save up enuff $$ for my stainless sh*t, but I know another kid that will let me have his ITR system for like $100. I wanna get the GSR stuff just cause I'm getting it for nothing, but can I expect to see anykind of power gains over the stock civic stuff? Or should I hold out & get the ITR stuff for now? Or will either setup not make much difference anyways?
I don't have a whole lot of mods done to my car yet- removed airbox, straight-thru muffler, underdrive pulleys, thats about it...

Any ideas?
Thx

either setup will not fit without modification

yes, that is true. the bends on the exhaust piping are different. maybe custom piping and the gsr muffler.
