Comments about Dynomax Mufflr-Ultra Flo Wld:

The title of this part is wrong. Thank goodness for part no. 17157 is Dynomax VT, which was what I intended to get. Very quiet at cruise, but the smallest application of the gas pedal it get really loud quickly. I don't mind the sound though, very deep rumble. Couple with a 3" exhaust pipe from the cat back. Also seems to increase gas mileage a little.
