Another vote for "badass"....I have a BBK catless H-pipe and the Flowmaster American Thunder system. While I do have a small leak at my passenger side header flange, the exhaust sounds awesome.

American Thunder here. Love the sound. Not too loud, not too quiet......just right! HMMM, sounds like a fairy tale. LOL

American Thunder.

Don't worry about the phrase "screams up top." Everything screams up top. You want nastiness down low and at city speeds... American Thunder delivers.
