Hi.
I replaced my exhaust system from behind the converter back - done by cheapest garage
.............. but I have noticed since I drove away that appears to be little more noise coming from the exhaust than noticed when first got car. It sounds like noise is coming from about the converter area or forward.
I have not had a chance to lift the car and crawl under to see if can spot anything.
Question - Is there a gasket or anything that the mechanic may have forgotten to replace?
Thx.
Bob
P.S. Yeah, I know............. you get what you pay for!

 

Quite possible...
