That's a good question about the rear diffuser however mine is stock except for the added piece from ZL1 addons.. I know for sure John doesn't make parts that aren't functional. No noise at all when removing the suitcase I know for sure



Flowmasters welded on to my stock NPP tips

Are these mufflers setup internally to bypass any baffle when the valve opens? Otherwise i dont see the NPP doing anything other than turning a dual tip into a single tip muffler. Im trying to grasp how it works mechanically as the pics of the stock NPP in the cutaway clearly show us exhaust gets directed either thru or around a baffled portion of the muffler depending on valve postion.
