can somebody please tell me if anybody has put true dual exaust on a hemi. i did a search and came up with 2 responces and one of them was mine. i want to know if there are any benifits from a cat back system? somebody out there has to know what cats to use and if there is a kit for 02 sensors.

 

Catback is simpler to install and has some sort of company's backing. True dual could get messed up if you don't use the right diameter piping and you'll lose HP and Torque. It IS possible...but why spend the extra money on a second muffler and H-pipe unless you're getting the engine supercharged, turbocharged, or taken to the track?
