Ok so I have a 2008 ram hemi with the mds and I put a flowmaster super 10 duel basically like straight pipe and the damper is off. Now is it possible I can lose hp cuz I feel like I have but not sure. the exhaust is too loud thinking of going with magnaflow just one exit pipe to help with the drone when it shut off cylinders.

 

It's loud because of the type muffler you put on (10 series) which I didn't even think they sold anymore and you cut off the resonators

I hope you didn't buy the 10 series thinking it was going to be soft and quiet. I had two of those on a 442 years ago and the drone was wickedly insane with them. It was hard to have a conversation in the car.
