I have a 2020 Charger Hellcat Widebody. Yesterday I noticed a vibration On my driver's floor And on my gas pedal On acceleration and deceleration. Eibach lowering springs, mid muffler delete and intake are my only modifications. Has anyone had this issue??? Help! Going to take to dealer and no lights are on dash, so sure I will be told it is fine or cant duplicate. Thanks in advance

All the mods done at once? The mid-muffler delete on mine was done "poorly" which caused issues.

Mid muffler delete was done first then intake then lowering springs. On another chat, someone told me check the mid muffler delete could be rubbing on a cross brace. Going to put the car in the air. Did you have same vibrations at the floor

It sounds line the cross brace, I had this issue with the AWE when I installed it. The fitment was terrible. I had to add about 4 washers under both braces to get it to stop vibrating. 16 Charger Hellcat for reference.. I did not have issues till I installed the exhaust. Check to ensure there is enough clearance especially on the rear brace

Yes, I felt it because the replacement pipe was touching the crossmember and vibrating through the floor.

Its not all the time. Was yours consistent? Today was only when car was warmed up and after a decent pull when the car was slowing down.
