Hey guys as some of you know im in the process of changing my flow 10 dumps. just too much interior noise and vibration. anyone runnin mac pro dumps? how do they compare? how much vibration on the inside? Just tryin to see what they sound like. Let me know if you like the mac muffler sound or single chamber flows better. (its really going to help me choose what to do)
thanks

I have never heard the flowmaster 10's. Didn't know they existed. Mac's sound really good. I have the produmps and they have a nice rumble to them but I like the sound of tail pipes better so I cut off the turn downs and put on the 2 1/4 tails I had laying around. I don't have any carpet so it resonated in my car with the turndowns but I'm sure its a little different with carpet. If you cut them off and turn them out to about a 45 deg. they won't resonate as bad from what I hear.It would sound much better with 2 1/2's but I don't have the cash to get them. I dont' know if MAC's True fit setup uses the same mufflers as the produmps. Mjr has a few clips of one of his stangs with a mac setup that came with tail pipes.

im thinking of putting tail pipes on these mac pro dumps as well. so dats perfect. the flowmaster 10's are loud and deep but they resonate way too much. and i dont want it that loud. ima try to swap them for the mac pro dumps and just add tail pipes tomorrow then. can you tell mw a lil more of how they sound?

Other than they sound mean, in the lower rpms they have a deep sound to them then in the upper half they sound like a race car. Not straight pipe sound but good toned sound. Look up Mjr's photobucket and watch his vid's at the track. My 2 1/4's kinda make it sound like an old stright piped truck when I am next to the concrete barriers in the constrution zones doing 2500+ rpms but I also have a carbed motor. They may have a slightly different tone on a EFI motor as well. All in all I like my MACS alot more than I thought I would. I wanted flowmaster 40's but latemodel didn't have them in stock when I went to their wharehouse so I opted for the produmps instead. Plus with them already having the flowtubes welded on they were cheaper all in all and fit perfect with the MAC H pipe I bought as well.
