Well, it's been a while since I installed the Mid-America dual 2-1/2" stainless pipes and the DynoMax UltraFlow stainless mufflers, so I thought I'd post a bit of an update, for those considering a similar mod.
First, problems: so far, the only real problem, is that this car was originally equipped with only one pipe through the center area, so there was only a hanger on one side. That led to some drooping, and the occasional ground contact, from the other pipe. A couple universal hangers cured that. Just something to be aware of, if you put dual exhausts in a car that originally 2-1-2.
Feel: yeah, you can feel these exhausts. I mean, standing behind the car with it idling, you can feel the exhaust vibrations in your gut. Very cool
Sound: driving around town, it's really quite comfortable. There's a bit of resonance between about 1300 and 1600 rpms, but it's not bad - just a hum added on top of the exhaust note. I really only notice it because it corresponds to the 35-mph-area, which is a common speed to drive. Actually, you can drive by exhaust note, if your ears are good, and not vary too much at all On the highway, it's a little louder, but a lot of the sound get's "washed away" by the wind, so it's not that much louder.
The big fun, however, comes when you open it up. That rumble becomes a roar. It's definitely loud, but not painful. Outside the car, however, is another story. Now, normally you don't get to hear what your car sounds like, from the outside (other than when it's idling). But, I recently had cause to pass a minivan (she was doing 35 in a 45 - reason enough), and I had my windows down. Well, as I pulled past her, the sound reflected off the flat side of that van, right back into my passenger window. I really can't describe it, but it was reminiscent of Nascar Now I know why people always look up real quick, when I push the pedal down
All-in-all, while I think sidepipes are cooler, this is one of the best muffler-equipped exhaust systems I've heard.
