can anyone help? my '01 multipla jtd has a rather annoying exhaust blow. it appears to be coming from a 1.25" stainless pipe located above turbo, below air box. theres a small stainless clamp holding the 2 parts of the pipe together. its seems to be leaking from there. firstly what is this small pipe for? why on earth would it start to leak from there? is it safe to just put exhaust paste on joints? cheers in advance.
