They do say that it won't void the warranty, as long as it's not the cause of the problem. Being from what you just said here however, it does look like it would be the cause of the problem. Well, I guess that idea is out. That kind of sucks, not that I had an extra $5,000 to throw around on a supercharger as it is. Heck, I don't even have the SLP Loudmouths, or the Dynomax, exahust that I want on my car now and that's only $400. And had I not spent that on a lawyer for a traffic ticket and court fines, total of $541 I'll explain more if needed, then maybe I would have that exhaust.
