I just recently picked up an 04 Mach 1 with the 4.6L DOHC 32v. I was looking to add a Cat-Back exhaust system. I have found a system from Flowmaster and a system from Magnaflow. Both are stainless, but I was hoping to get some feedback with your opinions. Thank You.

Stainless Steel SLP cat-back PowerFlo exhaust

well ya got chambered muffs (4-5 hp gain/deeper sound) or straight-through muffs (8-10 hp gain and higher pitched sound). Popular as of late are SSS, Borla Stingers and SLP Loudmouth II because they have the flow of a straight-through but have somewhat of a deep sound. I started a "Mach 1 Exhaust Notes" thread and lobbied for it to be a sticky but not sure what page it's on now but it'll help ya. Also, look through youtube and streetfire. It's all in what you like for your Mach.
depends on what kind of sound you like. if you like it a lil raspy then something like a strait through muffler will be what your looking for if you like a deep muscle car tone then chambered is what your looking for. i personally like the chambered sound better i love my o/r H and flowmaster set up.
