Q: Exhaust flex pipe needs replacement

asked by on July 11, 2016

My exhaust flex pipe is damaged. I need it replaced and want to buy a new one. There are many different sizes on the internet that claims to fit a 2005 Nissan Sentra. I have no idea which one to buy. Ive already bought the wrong size and sent it back. I looked under the car and measured that its approximately 7-8 inches long. I dont know what the diameter would be. I have two questions. 1. What size will the replacement be? Diameter and length. 2. Am I able to buy just the flex pipe or do I have to replace the whole exhaust pipe?

My car has 110000 miles.
My car has an automatic transmission.
