Car is in limp mode after muffler delete.
So I deleted my mufflers. Did 2-3 wot pulls and car is in limp mode. My tranny mount and motor mounts are no good. Car is shaking like crazy on D. Car is legit shaking as if in hitting pot holes. Any ideas?

The flat mounts could be affecting the crank sensor. Check for codes.
Note after engine mount replacement you are supposed to re adapt the flywheel( crank sensor)

I just added cutouts and beat the crap out of the car then 10 miles home. No problems with loudness. That is the benefit of the cutouts, I can close them and go back to stock when I run out of advil lol
Try the reseting if you havent...
1. Turn the ignition key to the on (not start) position.
2. Press the gas pedal to the floor and hold for five seconds.
3. Turn the key to the "off" position (don't remove the key), then release the gas pedal.
4. Wait at least two minutes for ECU to reset.
I do this almost weekly. The car feels and shifts a little smoother after doing so.

With an aluminum frame, any metal to metal contact will make the car feel like it is shaking apart!!

Agreed, I also have not experienced limp mode after cut out install. Broken connection to O2 sensor? Muffler shop removed rubber exhaust mounts to install? Exhaust hitting drive shaft?

I too, have cut outs. Installed right after the x-pipe. Uh, it's loud. After letting a gran sport vette taste my rath, he pulled up and said "man, I think you blew out a muffler". lol

I told him I was too busy texting and didn't notice. I didn't give him any time to respond as I put up my window. I think he was upset by my comment? I noticed his lips were moving, but my tint was too dark to make out what he was saying. lol

There's about 7-8 shops that either didn't have a computer for it or didn't work. I'm afraid the new spark plugs I installed might be the problem. I replaced the stock ones with Bosch fr6mpp332 plugs. Right after full throttle this happened. I was thinking to throw on the original plugs that a arnt terrible. Will the car still be on limp mode even after spake plug change if the spark plug was the problem.

Ok guys figured out the problem!! There's what looks like a power supply for the spark plugs that have 4 clips. 1 of those were not clipped on. The clip is actually broken. I zip tied. Cel still on but everything is running.
You can actually see red wires. That was the one sticking up.

Dude. It's beyond obnoxious loud. I have no 2nd cats, res, and muffler delete. It's louder than a Harley Davidson. There's no way I can drive with the car like this. I was thinking adding the resonators hoping it will be loud but not to the point where people in the street are pissed off at me driving by.

Deleting the mufflers is a huge weight savings and I got bored with the stock mufflers. I saw some videos that didn't sound bad. It doesn't sound like "trash". It's no eisenmann or meistershaft but I wouldn't say trash.

I have the same exhaust, minus my resonators. Why don't you but all that stuff minus the resonators? Mine really doesn't drone at all aside from in low gears as slow speeds. Heavy acceleration and on the free... Zero drone.

I had the mufflers with cats and res in place. It was really restricting a lot of sound. I then went with the 2nd cat delete I still felt I needed a bit more sound. I then took off the resonator and it was louder on wot which I loved minus the drone on a ridiculous level.
