Eliminating Rasp

[StingtheJeep]

So recently got Ultimate HFC downpipe and Midpipe installed. Stud was broken but repaired. I have MBRP exhaust with this set up. I've never heard such a horrible rasp, bean can. Metal on metal sound before coming from V8s. I installed two Vibrant Ultra Quiet resonators on the MBRP. It helped a good amount;I do have a lot of exhaust leaks, which will be fixed Monday once welded in . Now if I were to get rid of the Xpipe for the MBRP would this eliminate the rest of the Rasp? I have rasp from 2k to 2.5k rpm. I don't hear it just sitting and reving only driving. Under WOT it complete goes away, under heavy acceleration when it switches get jn that rpm range you can hear it. I love this stinger that's the last sound I want to hear and others. So would a true dual help, I've read that Xpipe can add rasp.

Should get rid of most of it if you get rid of exhaust leak.

I have the same problem, catless primaries, catless mids, stock catback. The idea was all the performance but less of the sound. Instead, from about 1.5k - 2.5k rpm, there is this apparent rasp. It sounds like its coming from my mufflers. The noise it makes sounds like there would be a nut just loose within the mufflers at those rpms. I have no exhaust leaks as I've looked for the problem in case that what it was. I don't know what to try next, I am considering Tork Motorsports' muffler delete n seeing if I can weld any resonators into it, need be.

In my experience secondary cat delete just equals rasp at that RPM. Drove me crazy.

I got vibrant ultra quiets, got rid of 90 percent of it. It's there when engine is cold, like 60 percent better. When warmed up almost gone. Other resonators I tried didn't work. Vibrant ultra quiets are the only ones.

This is before the vibrants
Then after

That is an impressive difference.

On what section did you put the vibrants on?
