OK then, I'll reword this. If i change to STI DP and Exhaust, Which I am sure has Cat in it, will this change cause all claims motor related to be denied? Is that clear enough for you? The reason I asked this, Previous Posts did not address my specific question about Using Factory O.E.M. parts probably puchased through the Parts department and not aftermarket, Do they not trust in the reliability of their own factory parts and Technicians? Maybe you should read previous posts.
