Resonators: Keep or Cut?

So I'm doing a DIY exhaust setup after putting in Solo Axle backs earlier in the year. My plan is to delete the mid muffler and replace it with an X-pipe and later this year Kooks catted Shortys. I can't decide whether I want to keep the resonators or not. Own their own do they serve a purpose like reducing cabin drone and would removing them make the car too loud?

You are doing it wrong. Shoulda bought headers and X pipe first and left the mufflers alone. Now you're going to end up up with a annoyingly loud car once you put headers on. At least you don't have a rowdy cam.

Should have just waited and bought the Solo full Mach Shorty Catback with the connection to Kooks headers. Not of fan of hacking and cutting an exhaust. I like things clean.

You also have option to get what's missing from Solo and hook it up to your axlebacks.

Not sure how the car would sound, cant help you on that.

I had to do something to it. One of the mufflers were rusted completely and sounded like a fart box at high speeds (not to mention the horrible drone).

Getting the Solo completion kit is an option too.

If you only want to do it once, get a complete system and forget cutting it up.

I have a perfectly good "already bastardized" mid pipe with the solo axle backs that went with them. That said, it would be pick-up only. Absolutely NO way that I'm going to be able to ship the full section in an economical way. So if you aren't in NC.... well.... pretty much a non-starter. I could cut you a deal though.

I'm starting to lean that way. I'm looking at the Solo Street Race kit and then selling my axle backs to recover the cost.
