[FLYINGBADGER2006]

I just had Bergstrom Hummer install a SMA Dual exhaust on my H3. And here are my thoughts. The exhaust note is much louder when accelerating from 0 to 50. Once on the highway the exhaust produces a louder than normal mellow drone. I have to turn up the radio a bit louder now to overcome the exhaust noise when driving. I didn't get a chance to guage the MPG yet. I will soon. I have the K&N CAI installed as well, so with the combination of the two I hope to see a slight change in better gas mileage. As for performace I do notice acceleration is more responsive. But without the stock air intake resenator and the stock muffler with its baffles and resenator to keep the loud noise at bay, I sound like a old 77' Datson B210 with a bad exhaust leak doing a 1/4 mile at Pomona dragway, thats if I really step on it. Also what I noticed is when I take my foot off the accelerator and let the H3 cruise, the SMA exhaust note changes as the gearing changes, as if the downshifting note goes from low sound to a lower muffled roar. I do like that sound. It's normally as I exit of the Interstate and ease off the gas pedal I will get that transition in the exhaust sound.
Overall I do like the look it gives from the rear, with the chrome tips. I would give it a 9 out of 10. As for the sound, (given the the fact that I know its only a 5 cyl powerplant.) I give the sound a 4 out of 10. As for gas performace with the CAI and the exhaust, I will have to let you all know later. Here are the pics.
