Get the resonators and just dump off the catback.

Be more tuned sound with the full catback and a tad more quiet but with the dumps it just sounds right being a muscle car makes it sound dirty.

I've never spent money on a cat back always just dumped it off after mid pipe using 2.5 inch tubing.

Oh ok but like what's the difference with buying the resonators and welding it to my stock catback? Just the stainless steel right but sound is the same right?

Oh I see. ok your stock exhaust piping (mid pipe, and catback) is 1.5 or 2inch thick I forgot which it is.. But all aftermarket catback and mid pipes are 2.5 inches thick so it'll sound more open up, more loud, idk if you'll be too happy with just the resonators on a stock catback. I never heard anybody doing that.

So it's just better to buy the whole catback huh... Is this how you dumped it? Click image for larger version

It's better either buying the whole catback system or just dumping it off.

Mine isn't dumped like that. My resonators are welded to a flange to bolt on to the mid pipe, and I have 2.5 piping flaring downward and kinda outward to the tires.

I got the whole catback. For one your old exhaust is probably welded in and you get nice tips. Dumping it will not make it raspy whatsoever it will sound like a foxbody almost putting the pipes on after the muffler is really loud
