hi i cut my stock muffler out left the two resinators in and replace it with a masterflow 50 hd. now i'm hearing noise like i have a jake brake. has any one having that problem and what can be done to solve that noise

 

That is your MDS deactivating 4cylinders. I assume you have the Hemi? You can buy a handheld tuner to disable it or simply press your tow/haul mode button everythime you start your truck. Tow/haul does disable 5th gear, but 4th gear is still an overdrive gear.

Both Tw/haul and O/D off disable MDS.
O/D off disables 4th and 5th gear though

 

thanks what kind of exhaust do you have

 

Magnaflow dual side exit.
