2 chamber flowmasters are pretty loud....i think those are quite a bit louder than mac, but i'm not 100 percent positive, i don't think the hp gains will be much different between the 2.

Flowmaster has to high of an idle and an annoying sound on the highway...Go with Mac..If you have a older fox were ur bumpers arent cut yet, go with the dumps, other wise go with the tips. With the dumps your goona get fumes into ur car....Go with Mac 2.5 into 3 or 3 into 3.5.....Also they dyno there products, go to www.macperformance.com and see if its listed for ur yr...if not i no its in the free magazine....

will it provide a deep more agressive sound than flows, I have dumps now Im not worried about fumes, I drive with the windows up mostly and im hardly in stop and go traffic for it to effect me. will it sound better with the mac pro dumps?

Heres they way I would decide........Do i have holes cut in my rear bumpers already? If i do then id go with tips, if not i would go with dumps.....It might seem louder only becuase the exhaust is echoing of the ground....... I like the mac 100% better than flowmasters....
