I have a 1995 F-150 5.0 L with hedman headers..... I now have an exhaust leak on the right side, it sounds like its right under the passenger seat. Id like to not get new headers and i know that sometimes it can be problems with the gaskets and was wondering what things i could do to start ruling out different parts of the exhaust.

 

someone on here mentioned attaching a leaf blower onto the tailpipe/tip and letting it run while I guess you get up under the truck with a squirt bottle of soapy water and spray it on or around suspected areas. This sounds a lot better than running the engine and crawling under there with all that heat and burn potential.

 

it was a shop vac, turn it to blow and duct tape it to the tail pipes...... rest is right...
