    5.0 Great System, Easy to Install!!!

    System installs easy, fit was great, you dont have to cut the stock exhaust if you have a couple of jacks and get the truck high enough on the passenger side. I went with this system bc I wanted tone but not to be obnoxious, its perfect. Nice rumble at start and acceleration but doesn't over power radio and Bluetooth. 99.9% Drone free. Every once in a while if the shift is right in V4 you get about 1 sec of drone but thats it. Only down fall was it took 2 weeks to get from 4 Wheel Parts and it was IN STOCK!. One of the other Big parts suppliers would have been 2 days but 4 Wheel drive had a rebate.

    4.0 Very easy to install

    Great quality and very easy to install. Also looks very good. It's a little louder in the cab than I would have liked, especially at 1800 rpm's under load. Sounds like a typical Flowmaster.

    3.0 Very easy to install

    Very easy to install and great design. It's a direct fit. It was louder than I expected and wanted. Had a Gibson cat back in my 6.0 Suburban and loved it, this flowmaster has an annoying drone in the mid range rpm's. I am thinking about reinstalling the resinator. My 20 year old loves it.

    Q: Can you verify this #17278 will drop-in fit the QUAD CAB (4 door) 4.7, SLT?  Yr = 2000. I see only entries for standard and extended cab so this is unclear for QUAD-CAB.  If not what PN would be?  Thank you. Answer this question

    A: This part is not cab specific. Per Flowmaster's website, this part fits 2000-2003 Dodge Dakota truck with a 4.7L, 5.2L or 5.9L engine and fits 2/4 wheel drive models and all wheelbases.
