Taking my 04 HEMI to an exhaust shop tomorrow to get performance muffler and duals out the back with tips. They've got several different brands of mufflers, and I'm not sure what I want to go with. I want an exhaust I can hear (such as a flowmaster 44), but I also want a muffler that flows well -- I plan to get a Volant CAI intake and I want to have lots of air flowing through the engine. I guess I'll ask them what they recommend.
Also got a superchips coming via UPS tomorrow. I'm pumped! If I get a chance, I'll post up a pic of my set-up and let you know how I like it.
