I'm with Squid. I'm going to leave my exhaust stock. Aside from just tampering with the exhaust system, isn't it against the law as well? That is coming a time where the long arm of the law is going to be felt in the area of emmissions. In Atlanta, emmissions are checked as you enter and exit highways in various areas. Your tag number is also photographed.
Squid, I'm running strickly Texaco here in Ganiesville. Big difference. I also stay away for pumps that read min. 40 cetane...a real giveaway. Thats what the big boys use, their trucks are not equiped with DPF's...yet
