Hi guys i was wondering if you guys have the same problem im having? I mean when im driving my the whole car would smell like exhuast i changed out my header gasket and my flange gasket any idea where the leak is coming from? I mean its really bad. Let me know thanks

 

do you have a break in the exhaust somewhere near the cat area? If you are running a CAT is it clogged? Is it possible that your header flange is warped?

 

Im running no cat im gonna have to check again to see if there is any holes on the piping. But i dont think the flange is warped cuz i just changed the gasket but you might be right.

 

Check it with a straight edge. That would be the only thing that I could think of unless you have a hole in your floor where exhaust is coming through also. My buddy had a bad exhaust leak and found a hole in his floor board, so may want to check that.

 

alright thanks for some advice. im gonna try everything cuz that stuff stinks real bad feel like passing out sometimes driving in the car lol.

 

pour some fuel injector cleaner in the brake booster vaccume hose. it will go directly into the intake and start to make your car smoke(its ok to do this it actually cleans your injectors and intake ports) wait for the car to start smoking and look all up and down your exhaust. my cousin had a leak and couldnt find where it was. turns out, it was right in the middle of the header where there was a bad crack under the heat shield
