How to get rid of the rasp in my exhaust sound?
 

So, my exhaust consists of Borla UEL header, Perrin over pipe, Tomei titanium front pipe and Perrin 3" resonated cat back. Yes, it's loud and yes, it smells because I have no cats, but I'm ok with that. What I'm not liking too much is that when I really get on the throttle it gets pretty raspy outside of the car. The in cabin sound is nice and mean but I want to get rid of the raspyness outside.
I was thinking a high flow cat front pipe or the HKS dual resonated front pipe.
Suggestions? Experiences?

Here's my video.

turbo.

It seems like the only way to get rid of the rasp is to add an additional cat or a resonator. I have a catted header and had to swap a non-catted front pipe to a resonated front pipe to get rid of the rasp.

Saving up for the Jackson Racing supercharger kit!


Thanks! I figured as much. Guess I'll be getting the HKS resonated front pipe.

Yeah that won't help with the rasp. Go turbo. You won't regret it. I've seen plenty of folks get buyers remorse and switch later. Just my .02, but I'm biased ;).

You need a cat, turbo, or another resonator.

Woah you sure you dont have a Honda? lol jk.

But like everyone is saying you need another resonated pipe or go turbo :D

Yep, I'll be getting the HKS front resonated pipe.

I had the rasp come from my catless front pipe once I installed the header. I wrapped my over pipe once and front pipe twice. It got rid of my noise.
