Default Installed new Lethal Performance O/R H pipe...

Not very happy with the sound. I had the Pypes on there so it was completely straight piped. It was very loud which didnt really bother me but it was wayyyyy too raspy. I switch out the pypes and put back in the stock mufflers thinking it would help but it didnt...

I am not sure what to do. I think I am actually too low to install resonators anywhere underneath my car. Maybe where the cat is supposed to be? has anyone done this? Any other tips that could help reduce the raspiness? I almost just want to put my pypes back on and say eff it.

Removing the cats is the source of the raspiness I believe. Some staggered resonators may help.

I am more or less just trying to see if someone has put resonators in place of where the cats should be?

I understand why it became raspy and in order to fix it I would probably have to do some resonators but i am too low to put the resonators on the underside of my car.

You could try something like SLP Loudmouth 2's they are not very big and would probably help clean up the sound some.
