Ok the other day i was driving and after some time it started to make a sound like a thonk sound near the exhaust well i checked and it seams to be coming from the exhaust manifold but the thing is the geskets are new and it was tq down any ideas???

 

we'll need more info on the car. year, recent services or parts, mods, etc. when does this sound occur? is it at a specific rpm range or at idle, over bumps etc?

 

ok well its a 91 TII it has a redone turbo from Res and a front mount runing 12 its rpm and load changes the sound all the time also

 

A walk-around video or even a sound clip would be helpful.

 

YOur descriptions kinda suck man...

BE WAY more specific.
