Well, after getting my car back together after brakes(EBC's),Lowering 1", and having my ACR wheels chrome plated. I decided to do a little exhaust work. Here is what I found. First, cut the cats and, replaced with straight pipe left door resonators in for rasp damping. Second, cut rear muffler and, replaced with straight pipe. Also, added an H-Pipe at the rear to cut do on exhaust burble. The Mopar Computer has stopped any check engine lights and, fixed the lean rich problem. The car does not stink or, is it to LOUD like most people say. It sounds perfectly tuned. Now, here is the kicker. On the dyno the car did
425rwh & 470rwt SAE corrected with a a/f ratio of 11.9. The car took about 200 miles to correct. But, now is running perfect going on 300 miles in the last week(Lots of Driving). The is the best mod I have ever done of the 2 vipers I have owned. The reduced interior heat is amazing. Highway driving is still very quite no drone in side. This should anwser most of the questions you guys have asked over the last two weeks about the 00 Vipers with no cats. One last thing, the car passed emissions at idle and, at 3000RPMS. Tony
