SPINTECH 9000 vs MAC FLOWPATH

I have spent the past several days listening to exhaust setups and with the help of a lot of you and YouTube I think I have narrowed my choices down to either Mac flow paths or the spintech super pro street 9000. I have a 94 mustang gt with an off-road bbk h pipe. Which muffler is deeper and louder, the Mac flowpaths or spintech super pro street? Are they louder than the super 44? I'm looking for that deep rumble almost through board boat exhaust that just sounds badass, "blattt blattt blatt" sound not high pitched raspy. I have super 44 on now but they aren't loud enough at idle or deep enough for me.

Been a number of years since my MAC mufflered car went to it's new owner, but my Brother's spintech's seem to have a deeper sound. But his engine is also 116 cubic inches bigger that mine was.

sradtodrag do you have more pics of your coupe someplace I can see them? My hands down favorite Fox cars are 85-86 5.0 coupes. Best interior. Best dash. Best nose. Still had chrome trim around the windows. Perfect cars.

Its a custom. A guy at the local muffler shop has a mandrel pipe bender and makes the pipes from scratch.

I like the spintech's from the 2 vids he posted. A little more rasp with out the drone. Drone is cool at first..... but then you can't have a conversation while cruising. It's a toss up/ trade off or what have you.

WHAt are you referring to as drone tho? The deep bass sound? Cause that's what I love. Like when your idling and it's just gargling sounding

I have had both of them and Mac was everything I was looking for. Mac is also a better flowing muffler over the Spintech. When I had the Spintechs on my car I saw a gain of 2 lbs of boost. Went back to the Macs and boost was back down to 20 psi. Talk about a restriction lol.

Thanks! Appreciate the info, I think the Mac sounds deeper which I like, the sound techs have some weird sound when revved like a slight ping or something

The drone I'm referring to is real bad at about 1500-2000 rpms. It's the deep bass that rattles everything and sets car alarms off lol. It's cool for a little bit, but gets old and annoying in my opinion.
