I have a 2008 gmc sierra 1500, i want to put a super 44 series flowmaster on it what size inlet do i need?

What inlet does the flowmaster have to have to fit my truck?

  • you probably have the gm odd size of 2.75 (id). so 2.5 or 3 will work. you may need a muffler shop to make you adapters. Read More
  • If you are just cutting your muffler off and replacing it it should be 2 1/2 inlet. but you can go to any muffler shop and they will do it for you. they might even have the super 44s there. Reference:Have 2007 silverado with exhaust.
  • measure it with a tape measure then order or buy what you need

Other Choices:

In the field of full-size trucks, brand loyalty is an especially strong factor, with die-hards for the bow tie or the blue oval. But objectively, next to the F-150, the Silverado offers better steering and sharper handling, though some might like the F-150's interior design, which is more businesslike yet still upscale. Styling is a big differentiator; the Sierra has a softer design, while the other competitors have the more aggressive, faux-semi look in front. Fuel economy is a strong point for the Sierra; with the 4.8- or 5.3-liter engines, it gets better ratings in city and highway driving than all of its rivals with similar-sized engines--at a time when every mile per gallon really counts. The 2008 GMC Sierra 1500 has one or two fewer gears than the Tundra. The Tundra--especially in top-trim versions--is especially competitive with the Silverado, as it offers a comfortable, classy interior and 5.7-liter V-8 that's more powerful than GM's 6.0-liter.
