[68c10airstream]

In my 68c10 with a 5.3 4l65e, with sanderson shorty headers i used new gm mufflers that came from 88-91 suburban 5.7,7.4 single muffler system. the guy at the swap meet had 2 so i figured that if a bigblock can breath through a single muffler, half of my 5.3 can breath through it. The mufflers were long life stainless. Real quiet at idle, absolutely no drone, and the headers play their tune nicely when floored! 3.08 axle 1650 rpm at 60 mgh and 22 miles per gallon. The mufflers are pretty long at i think 22".
