Akra slip on is just the mufflers. No impact to smog since it couples up to the stock midpipe. Bassy but very miminal increase in actual volume over full stock. Some weight savings.
Akra evo also replaces the entire stock midpipe up to the header gasket. Eliminates primary cat which does the heavy lifting, secondary cat is maybe a 100 cell and it also has a different resonator. Cannot pass smog with the evo but the sound is immensely better than stock or stock plus rear muffler akra only. Plus majority of the weight savings comes from the akra evo midpipe.
With the evo you have to swap in the stock mid pipe with the akra adapters so you toggle between slip on only and full evo. Easy enough if you have a lift but paying for two swaps every two years is an annoyance.
