None with midpipe only. Usually this happens when stacking exhaust mods to going with a full system without resonators.

Catless downpipes/midpipe and a Race muffler will most times sound awful under load and get a ton of attention, including the unwanted kind. However, this seems to be where the trend is going - who can be the loudest. Keep the exhaust mods on the conservative side and it will sound fantastic.

Tall Tom Cruise is running ER Downpipes/PSI midpipe and should be able to chime in with his experience on his setup.
