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.

 

Go stainless. What kind of a sound are you looking for? Planning on midpipe or headers later? Congrats on the Mach and welcome to the family!

 

maybe later down the road i might do headers but not sure yet. right now i was just looking to do a cat-back exhaust and a K&N filter element.

 

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.

 

^+1 i have magnaflows and o/r h pipe because i love the muscle car sound

 

same here, best sound ever.

 

see he knows what im talking about, get the magnaflows

 

I'm going with the SSS adrenaline, good quality, great sound, awesome price.
