exhaust w/ catless vs catted DP dB levels?
anyone measure the dB levels of their exhaust and DP combos? Some tracks have max sound limits - ie Laguna Seca has a limit of 92dB @ 50ft.

dB readings are tough to judge because there is are so many variables into how the readings are calculated. But a good rule of thumb is that a catted downpipe is going to get you 80-85% of the same sound as a catless setup. |

Also, catless will produce more exhaust smell and soot on the rear bumper. What our catted downpipe (Sport Cat) provides is a simple, reliable bolt-on install that produces great power and sound. All while be CEL-free, no tuning required, clean rear bumper, and little-to-no smell. |

Be careful if Laguna Seca is your preferred track. There is zero wiggle room/flexibility there. They will Black Flag you immediately if your car is over the DB max (3 Black Flags and you are done for the day). Valvetronic exhaust would be ideal here. For reference, stock 458 and axle-back 991 gt3 are still way too loud.

If the car has a stage 2 tune and fuel smell is not an issue. Go with tune + catless
