had a 2002 silverado 4.8 with a moroso spiarl flow dumped at the rear at first and it sounded ok. Then put a 3" tailpipe on it and it had a real deep mellow tone to it.

Then switched to single chamber ebay muffs (like flomaster 10 series) it sounded NASTY. 2.5 true duals, tail pipes tucked up in the bed corners. no drone at all.
