Thread: exhaust leak

ok i know i have an exhaust leak cause my whole car vibrates when i step on it. i just welded my cat back all up last night so i know its not that. so is the only way to check for a leak to put your hands around the exhaust?

you could hold a piece of paper near it or something else soft that you could see the leak on. It should move the paper or whatever else you are holding that is soft next to the leak...

since when does vibration = exhaust leak?

well what else could it be?

i dont know, im not in your car. what does it feel like? what does it sound like? any codes?

well it just vibrates i cant really explain it. but ever since i put my new cat back on it been doing it

Headers making contact with the floorboard? You do have Pacesetters

Is it resonance or a vibration?

Does your catback have a resonator?

maybe the catback is a little crocked. when i put my headers on my catback got pushed back alittle and the catback would hit the underside of the car.

i do have pacesetters i dont think its leaking from the it doesn't feel like it coming by my feet. yes i do have a resonator it the same one i had on my slp cat back.

an exhaust leak wouldent vibrate. mine are still leaking some. the vibration would have to be something hitting somewhere. check over the whole system to make sure its not outta alignment or something.
