Hey guys, I have a 2006 Audi A4 2.0t quadro with a few s4 upgrades and a chip in it. It also has a magnaflow exhaust in it and whenever I step in it s bit I can smell the exhaust pretty easily through the windows. I'm not sure if this is normal.

 

Really shouldn't be able to smell the exhaust. Have the system checked for leaks. Might just be a loose flange somewhere or a bad gasket.
