I have had an exhaust leak for some time now and its really bothering the hell out of me. I thought it had somthing to do with my exhaust system, but today I just had a magnaflow cat back installed. Even after this install, there is still the smell inside the car. I noticed that there may be exhaust coming out the left side of the engine bay.

Anyone have any idea what may be leaking, what parts I need, and the approximate costs.
Thanks

 

what i would do is bring it to a muffler shop like midas ect ect, they will find the leak and it wont cost you a penny, the inspection is free, then get the parts you need
