Just added the Zoomers exhaust to my CSRT8 about two weeks ago.
Positives: 1) It sounds absolutely Bad Ass 2) Wife hates it 3) All stainless steel and shiney 4) Seat of the pants dyno says it's up 5 to 10% with no other mods 5) Did I mention the wife hates it now but loved it quiet? All of a sudden she prefers her car again 6) Starting the car in the garage at 5AM 7) Valet at the gym now leaves the car up front 8) That slight E55 advantage is toast.
Negatives: If you want a sleeper stick with the Lazy Boy sofa
Ron did video and Dyno on the stock car. We head back to the Dyno next week for the "after" tests. I assume the results will be on their website.
