i would say it's more of a slight rattle coming from the left hand side. i've taken it to get a 2nd opinion and the noise it normal they say however there was a section just before the cat where the weld wasn't all the way around the pipe. the mechanic said he could feel a tiny bit of pressure coming from there so i'm gonna take it back to the exhaust shop and ask them to weld it up properly.. i'm wondering now if i can just replace the back resonator to get a bit more noise.
suggestions?

cheers
