every other "loudish" exhaust ive had have all been loud as soon as i start up the car. however this one only gets louder once the car is warm. at the same revs when its warm it is alot louder than with the same revs when its cold.
...i am not confused about why it is louder, as that was the point of taking out a muffler, but confused about the way it becomes louder when warm.
