I'd go with Mac. I'm in the opposite situation as you right now. I have the mac catback but i have a catted x-pipe and i want an H. Just trying to justify the price vs the difference it will make. If you go with Mac, make sure you post up some clips.
i don't like the sound of chambered mufflers on my mustangs. Sounds too much like my Ford Tractor. Magnaflows
O/R pipes make our cars sound like beasts lol I'm thinking of picking up some Stingers today. But at $585 shipped, it sure is a kick straight in the nuts! :-(
as much as i like having a unique sound, mac ftw you wont be dissapointed....but if you dont like drone i dont recommend them mine sounds like flowmaster on steroids, I have BBK LT headers, matching offroad H with weld in mac flowpaths and it sounds mean as hell
IMO i dont like teh Stingers paired with an H pipe,horrible blat sound...eww...but difft strokes for difft folks!
Eh... Installed an old MRT Catted H I had laying around the garage from my old 04 Mach 1 on my 04 Cobra with Borla Stingers last night. At part throttle sounds great. When you romp it though, it sounds like one of those annoying jacked up trucks RAP RAP RAP RAP RAP Oh well, the mod was free and I prolly gained 10hp or so with it. If I get tired of the sound I'll end up ordering a set of Mac 3" catback. Got my Stingers used for $350, so all in all not a bad nor expensive setup currently. Rod
