Cliff, i run dynomax mufflers on mine, dont know about the db rating but they are a lot quieter than the flow masters i took off. The car picks up about 1.5-2 tenths with the headers open and 18" collectors. Somebody on here posted a list of mufflers and their noise rating a while back. Mick

I have 3" pipes and mufflers that finish in front of the rear axle, they both weigh around 50#. Isn't your new car lighter than the old one?. Mick

Got enough room for Bullets but was thinking collector mufflers could save some weight
The extra 40lb or so makes little difference on mine Are you coming out to race at MSA events? I have seen debris fly through the collector when motors let go, so I thought it may be safer to have a pipe just after or before the rear axle. HTH's

I dont think you will go slower in that car even with mufflers. Mick
