My car buzzes pretty bad. Put it up on the lift today thinking i might have an exhaust leak. Still finding mods the po did. I see a Torque solutions mount on the front and it looks like its a solid mount? Could that be the source of it?

Car is pretty quiet at lower and higher rpms. Also found a Alta hot side tube and the car has a aem intake.

My problem seems different than described there. More like a exhaust leak. Or a muffler droning. I've read others having a similar issue with alot of intake mods and no tune. Car pulls super hard and is quiet at higher or lower speeds.

 

Acceleration or deceleration?

 

At 65 mph it sounds like a car with a aftermarket exhaust droning. I see some soot on the muffler but every else looks clean.

 

I'm thinking it could be a slight exhaust leak at he downpipe gasket? I've read where others have failed?

 

Like the clamp that connects the DP to the flex joint on the exhaust is loose?

 

I'm thinking up high near the motor. I had it on the lift and everything underneath looks ok. Only soot i saw was at the back of the muffler. Weep hole?

 

Your DP could be loose on the turbo so it leaks a little.

 

thats what im thinking. its the only thing i haven't checked yet. gotta find some time this week.

 

pulled the heat cover this morning. everything looks good. The only place on the entire exhaust that i see soot is on the muffler right where the one tailpipe meets the muffler at the back of the car. Could i have a bad muffler?
