They do but there's no after market exhaust currently for the Rebel. The guys from Flowmaster and Borla said it would be a couple of months before they could get their hands on a Rebel and build one. I had a Borla on my 2010 Ram but the clamps kept coming off from the exhaust system.I've always liked Corsa Exhaust Systems.
The Borla sounds good also:
No they didn't give a reason. They just said that haven't seen the Rebel yet. The question is if all the 2015's come with the 4 corner air suspension then those should fit the rebel. Just like you said not much has changed but I'm not willing to dish out another 1k just to see.Did the companies you contacted say why their ram 1500 exhausts they already have won't fit? Everything on the truck is the same as 2009+ except for the grille, bumper and tailgate.
The last dodge I owned and traded in was my 2010 Ram 1500 and there's a difference but I don't know what the difference between a regular 2015 Ram 1500 and the Rebel. I'm sure I can get a pipe shop to costume bend some pipes and weld something together because I'm not a huge fan of bolt on exhaust system as I learned from Borla system.Im pretty sure it's different. I've been under Ram 1500's and my Rebel. Huge difference.
