DynoMax Super Turbo Muffler

This 1st gen Frontier was given a new muffler to replace the old swiss cheese exhaust.

The old muffler had holes everywhere and a terrible drone over 45mph, so I replaced it with a DynoMax Super Turbo Muffler and a pre-bent eBay special U-tube, cut and welded to desired fitment. The name sounds way cooler then I think it should, but maybe once I remove the second set of cats, I'll get a little more sound out of it. As it is with all four cats in place, it's too quite for my liking.

U-tube and U-bolts

2.25" U-tube.
2.25" stainless steel U-bolts.


Hangers were purchased off of eBay, and I just removed from the bracket, and bent to shape around the muffler. I was able to use the old hanger location and it held in place better when bent as pictured. See first picture for it installed.
