Well this is my current setup and it is really really really loud and very raspy. (Not how I thought it would sound) Is my header whats giving it this higher raspier sound? If needed I can post a video of a pull just to show.

Thanks

Catless or catted?

 

Catted Sorry forgot to add that I posted a vid of it

 

EH ****! My Car don't sound like that. I have BadMab, ZZP 3" Catted with 2.5 exit, ZZP 2.5 3 Chambered Exhaust. They sound BADASS!

 

Ye Im not so happy with my setup. How can I make it sound better without changing my catback?

 

Get ZZPs resonator. I was where you are. Installed their resonator and my car sounds so good now. Even catless it's super quiet.

 

I am curious why did you get GMPP Catback ? They are excactly same size as Stock Exhaust just to let you know and you're not gonna get HP out from that. It's not whole stainless, ZZP 3 Chambered is whole Stainless and best price on the market. Also they are 2.5 all the way and it will give you HP out of that. If you stay with Vibrant header and GET RID of GMPP Catback and go with ZZP 3 Chambered for sure that will put a HUGE SMILE on your face. Trust me! STAY on 2.5 don't go 3" unless if your car is 300+ HP then 3" will be perfect.

 

You are incorrect

Then OOPS! My Bad! LOL!

 

I spent a bunch of money on the gmpp so theres no turning back from that one. So I mean would just changing the header out make a difference I don't exactly want to ruin the catback if i wanted to sell it in the future. Does adding the resonator really make a big difference?

This sounds perfect to me imo. Atm I can't even hear the whine at all. lol

Most resonators are junk. I've tried many of them. I just installed ZZPs resonator about a month ago because my car was loud and raspy. Their resonator got rid of all of that. I'm catless and the only thing keeping my car from sounding like **** is the ZZP resonator.

Heres a thread I made battling for quiet exhaust. Go to the last page and listen to the before and after ZZPs resonator.
