hi has any one experienced more vibration on the car after converting to dual exhaust? my car seems to be vibrating from under the car but only when stopping kind of when the rpms reach their lowest point right before picking back up. car is a 2002 auto no engine codes and all the maintenance is up to date so is not tune related and the hangers are in the stock places so i dont think is hanger related, but it seems to come from under the car, could it be the brakes? tranny or something else?

 

well let's see, no vibration before exhaust, which is under the car, now vibration after exhaust, which is under the car...

Take it to whoever did it and have them go over it to make sure nothing came loose.

 

definitely the exhaust as ryan said bring it back to the shop
when i had mine done the drivers side tail pipe was hitting my gas tank
