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.

 

Magnaflows seem to rumble hard and loud but aren't as crisp and muscular sounding as Flowmasters. This is just my opinion, based on GTs, not Mach 1s. I currently have a catted x-pipe and SLP exhaust with Loudmouth 2's. This setup has a nice, deep growl that is still relatively quiet cruising under 2000rpm's, but open up quite nicely when you punch it.

Try these vids for comparison-

Good information above but I recommend posting this in the Mach 1 section for a better response. Here is a link -> Link <-

 

thank you for your input...checking out the Mach 1 section now

 

Its more than cat back, but if it were my car this is what I would build up to. Dont know who's car it is, but it sounds GREAT!!!
