Sound Louder and More Agressive

Hello guys,
I have a 2.25" cat back with vibrant muffler (here what my car sounds like:
) and I want it to sound louder and more agressive. What could I buy to achieve it. I know a down pipe and headers would make a HUGE difference but I don't know what to buy...



K&N CAI - Vibrant Catback 2,25" - 17" Voxx Wheels - Gen 2 Projector - 30,000k HIDs (Purple) - 3,000k HIDs Fog lights (Yellow) - 5% tinted windows - Eibach Sportlines - Front SS Bumper - Rear SS Bumper.

You have the zzp resonator too and it's still raspy? Dang, scratching that off the list of possible upgrades.

Your vibrant exhuast sounds good in low rpms, but way too raspy at higher 5k range. You should add 2.25" piping, 18" vibrant resonator to calm it down from rasp. Add a header and then an intake. That will do it just fine

I shouldve specified!!!!!

I have the 1st gen ZZP resonator, its 2.5" in with a 3" body and maybe 21" long or so.




Since then to take into account the noise of SC cars, they switched to the "whisper" resonator 5.25" diameter 27" in length.
