How much louder is the TSP downpipe over the OEM downpipe with stock exhaust?They key to maintaining a good exhaust sound (and reasonable volume) with an upgraded downpipe is having a resonated exhaust. Thankfully in the FL5 market many exhausts are offered with a resonated or non-resonated option, which allows you to adjust accordingly for your downpipe, if one decides to go down that road. Non-resonated often suits the factory downpipe well but can sound horrendous with an upgraded downpipe.
