Right on ^... if your running an SR with a straight thru pipe, forget it. way to much bark.
you will need atleast a say - assuming you have a cat... a small center muffler or resonator and a rear muffler... cannon or whatever..
no screamer pipes.
can grab cheap silencers off ebay to fit in the tail pipe.
if you have a good Jap cat back system, (not some Just china piece of rubbish) for EG, you will be fine.
