MPE is more basic than MPPSK and doesn't include a tune. This just has one valve on the right side that closes in comfort mode and opens in sport and sport plus, it may be slightly louder than stock and not have the gunshots of the MPPSK, so not as dramatic as MPPSK and no performance increase, so it is also less expensive. There is also an MPE for the 340 with no tune. The MPPSK has two valves that open on each side and are closed in comfort and below 4K rpm, when it's open you basically have a straight pipe cat back exhaust vs. this the exhaust gases still pass through the muffler when the valve is open.
