I've researched this setup and probably read every forum thread on the damn internet about it. In short, I'm still super torn on what to do and have held off for now. I really would LOVE to somehow hear it in person. Nearly EVERYONE will say if you delete resonators with Roush ABs, do NOT mod the exhaust any further (x/h pipe, cats, headers, etc). In general, you are going to get some that say it sounds awesome and some will say Roush should be left alone. If you were to poll it, I'd guess 30-40% like it and I'm basing that off all the threads I've read. To quickly sum up what I have read... without resonators it will get raspy around that 4k+ rpm range. It will also get LOUD at and above that range. It will pop a lot more on downshifting and letting off the gas in the higher than norm rpm ranges (3k+). The tone will change a little bit, some say it loses a little of the deepness but has a more aggressive and angry tone (which to me, that is kind of contradicting...?). Also, you can still keep it relatively quiet if you are taking it easy so in short, LOUD when you want to be and quiet when you want as well. I think that's about the gist of it!! If you do it, be sure to post back here on your results.
I've seen ppl post that they paid anywhere from a little under $100 to a couple hundred. Keep in mind, some just do a simple resonator delete replaced with 3" pipe in their place and some go with 3" pipe upgrade from cats to stock H then from stock H to ABs. Check out Sam Stoppler, Race 302 and Toxix on youtube. Some good vids/sounds of the roush+res delete.
So i went ahead and got the resonator deletes and put an X Pipe. But TBH it sounds the same when idling and when you give it gas its a little louder. Now i just gotta have someone drive my car so i can hear when it passes by.
I had that setup and it sounded great but when I got cat deletes it sounded terrible. Now I have roush a/b with cat deletes and glass pack mufflers in place of the resonators and it sounds amazing but extremely loud as well.
I am running the roush with long tube headers and x pype. It is loud as hell when you really get on it, I don't think you driving will be very pleasant if you remove the resonator
I have the Roush with resonator delete, everything else is stock. In the video you can hear the pops that it makes when decelerating under the overpass. With the resonators in, it was more of a gurgle. Cold starts are a lot louder now. https://youtu.be/GZQOKND51uw
