flows & mac

rppngears · 08-12-2002, 10:37 AM

Can anyone tell me if there's a difference between the way a flowmaster muffler sounds compared to a mac muffler. If there is, can you describe the difference?

Some people would say flows have a tinny sound to them. I personally like the sound of flows. Ive only heard one car with macs and that was an 96 svt. They have alittle more rumble at idle than stock and alittle louder than stock when you mash the gas but other wise they sound stock. It all depends on what you want, alittle more rumble or full out roar. Hope this helps.

The MAC Pro Dumps I have rumble real loud from idle to 1500 RPMs, then they quiet down. I don't mind this since I do a lot of driving at 60 MPH (around 2000 RPM)this summer, and the drone of an open h-pipe was getting old on a 2 hour round trip commute. They do start to get loud again at around 2500 RPMs.

Under hard throttle, the MACs are a little quieter than 2 chamber flows, but are definitely louder and a hell of a lot better sounding than my old 3 chamber flows.

I like them, but I also like 2 chambers, so it comes down to a personal decision. If I were you, I would listen to different sound clips of the two and go from there.

And one more thing on a quality note. The Pro Dumps looked fantastic and very well made. I was impressed. I think they almost have a powdercoated finish on them or something. My MAC aluminized h-pipe doesn't have that coating and came to me very dirty(inside and out). I was not impressed by it, but it was just a $110 h-pipe. I really wanted a BBK unit, but couldn't afford it.
