should I delete the mufflers and resonators and then put after market resonators? I want it to have a nice sound to it and not just loud farts out the end of my car and if so what resonators do you think would be good for the job?

 

Don't do it. I would five $200 to have a stock exhaust again. Muffler deletes hurt my brain on drives over 15 mins.

 

If you have the OEM exhaust system you can swap out the mid-pipe for the coupe mid-pipe for better sound. You can also swap out the y-pipe to the HR y-pipe for even more growl.

If you have an '03-'04 it a dramatically better sound doing both mods, if you have an '05-'06 it's not as much difference switching the mid-pipe (still sounds better) and the y-pipe will still make a pretty dramatic difference.

These are also 100% bolt on OEM components, and you can usually pick them both up for cheap.

I would definitely go this route, proven to sound good, cheap, still have OEM components.
