L83 to L86 exhaust.

[Carlos Mendoza]

16 Suburban L83. I was thinking of using a y pipe connection for an L86 after the long tube headers with an L86 catback specifically magnaflow 19040 meant for Yukon XL & ESV to up size from a 3” to 3.5” piping. My question is everything should line up as far as exhaust hangers and such right? With it being all the same platform, I’m assuming it would. Thoughts?

As long as it's from a Tahoe, Yukon or Escalade it should line up. The pickups have different exhaust hanger locations depending on the bed length. I had to do some cutting and welding to get a Silverado exhaust on my Tahoe. I can't speak to the Suburban, XL or ESV, because I haven't seen those exhausts in person for a side by side comparison.
