    Default Altis exhaust resonance.

    just bought the new 1.6 Altis. The exhaust resonates excessively between 2000-3000 rpm, making the engine feel rough. Anybody else notice this problem?

    I had a similar problem back in 98 with the 1.6 gli. Indus mitigated the vibration by adding a clamp on weight to the exhaust pipping just behind the engine bay. 14 years later, they have the same problem!

    Does it make a tinny hollow sound?? or low rumble in the cabin?? the very first VW Golfs addressed this problem with a clamp it was actually made up of 3 layers of springy steel bolted together with a spring washer, the ends of this device were clamped to the exhaust pipes which were at an angle, this removed the resonance they faced it was specially loud in the 1.5 diesel and the GTI too.

    I believe this car also needs it or the weight thing (the corolla 2.0D air box also has such a weight)

    It's more of a low frequency rumble in the cabin. Could mislead you to thing engine not running smooth. I think it probably has to do with the exhaust system calibration, don't think indus folks would be using different exhausts on their cars, all probably the same, with very little engineering and check gone into material and quality control.

    So i'm guessing it's not a common issue - ahh, meaning indus won't really entertain without a fight.
