loud noise under hood, real descriptive title Options

[celicarocker]

2 days after i get all this work done on my car, another new noise starts. i was driving down the highway to go to applebee's and all of a sudden my car starts making a loud noise. the best way i can describe it, is like an exhaust leak, but under my hood... i tried looking when i got to applebees but it was too dark. im gonna check it out in the light tomorrow, but any have any ideas of what i should look for?

sounds like an engine is under that hood.










lol... jp. do any clutch jobs resently? or anydropping of the engines... anyways if u havent, then check under ur heatshield (if u still have yours on) and check any holes in the exhaust manifold, check for loose bolts, and if u dont see anything from the front... check ur o2 sensors... sometimes those come loose. and after that if nothing comes up it might be an exhaust gasket. and other than tha just check all the pipping from engine to cat. i just fixed my exhaust leakages... sounds hott again.
