I got a great deal on a set of slightly used(15K miles-no rain or snow)MACs(#TK2546)in awesome shape(guy polished the entire muffler and pipe every so often)and decided to give them a try. I'm glad I did as they aren't quite as loud, but very close! They are much deeper sounding and the overall tone is much better than the Flows. I really like the slashcut tips as they flow with the contour of the bumper quite nicely. The only thing I dislike about them is they are all shiny:notnice: That is so not my style. Since I'm going to keep them on, I will rough the muffler body up and paint them with high temp black paint so they will be hidden as the Flows were.

This is them, not MAC's pictures:nice:

Very nice.

I am planning on ordering a mid pipe soon and was wondering if the mac's were better than flows. It was between the two for me as I have heard the flows in person but not the mac's but from everything I have read, more than one person has done this swap and never looked back. "Sounds" like Mac's are the way to go.
 
Why ruin such a beautiful finish:) I think the MAC's have one of the best tones for our cars. Now that I've been used to them for some time now I need them to get louder with some longtubes eventually!
 
OMG do they drone around 1500-1800 RPM in the higher gears:eek: Oh well! Otherwise they are so much better sounding than the Flows. I will get sound clips today as I will be out and about with my camera and camcorder for a Stang cruise to a car show:nice:

mine gets real raspy around 2500 depending how hard I am on the throttle, quite easy to keep quiet if you'd like but that's never fun ;)
