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.
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.
i would go with the borla stingers. i have headers midpipe and flowmasters and i regret it..they sound good but cheap. the borla stingers have a very clean crisp sound to them and are very well made.
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.
