My resonator on my 2.3 16V has a hole in it, will I be benifiting the car by taking it out and adding a straight pipe to the rear muffler, or just replace it?

-What would you suggest for upgrading my spark plug cables?

-Currently suspension is eibach spring with bilstein shocks and it is way to low. Should I replace springs, put in adjustable spring perches, or buy bigger spring shims?
Thank you

new guy Joshua
