I believe they were just under the acceptable limits in decibles allowed. Quiet is not a word I would use to describe the exhaust note on the SRT-8 Challenger. Dodge qoutes 0-60 under 5 sec. Some mags have tested 4.7 and others a little slower. Depends on which test you read as to fastest and quickest times. I hope you find a Challenger in the flesh and come back and tell us what the deal is
