And I guarantee you that it is completely related to AMS downpipes. They even look cheap. If you want some SERIOUSLY correct DPs which are double-walled with proper 400 cell catting, no smell, lots of power increase, no rattles (no special gaskets needed either), GREAT tone then call Ron Performing Imports. 770-641-6202. They are going to run you approx, $3500 including shipping. Yes, they are expensive and they are TOP OF THE LINE quality, no bs parts. This thread would not even exist if everyone used these.
