My car sounds crazy loud now, got some FI RHFC and resonator and muffler delete but the car has a little rasp and it's way to loud any suggestions?

 

resonator and muffler delete? put that **** back on. At least the resonators. Noob

 

You're not hearing the rasp for the fact that it's so loud, but trust me, it's there. Literally any resonators will work, just depends on the total volume and tone you want to end up with.
For example, I have a custom Y-back exhaust, 2.5" pipes and 18" resonators. This alone is a good volume and nice clean tone. Sounds wayyyyy better in warm weather. The cold keeps the pipes from expanding so it's much quieter in winter right now. It will be a screamer come spring/summer though. Had a few warm days after having it installed last fall and man it sounded good. (I try not to toot my own horn but I love the way it sounds)
What's your end goal? BTW stock resonators are trash. You'll get much better sound with aftermarket resonators. Diameter of pipe you got put on has an effect as well. 2.5" pipe will have better high RPM flow and deeper tone than the stock 1.75-2.25" pipe.

 

I had my exhaust done at a local custom shop. His business has exploded in the past year or two and he does exceptional work.
