Ruell,

I wouldn't do this.  The purpose of a resonator in the exhaust system of 
a 4-cylinder is to remove a really loud BRAAAAPP sound, or as some may 
refer to it, remove the 'snapiness' from the exhaust note.  I skipped the 
resonator on a new exhaust system on my last car -- for about two days -- 
I couldn't stand the noise.  I like it loud, but this was annoying.  I 
don't think the resonator has a big effect on performance, since they're 
generally a hollow vented tube surrounded by an outer glass-packed casing 
(probably next to no back pressure).  I didn't notice any degradation in 
performance after reinstalling the resonator on my last car.
