All those pics of the 5” (and 6”!) look great!! But who made them?!?!
I know Carven and Moe’s makes 5”. Is that what everyone’s using? Any other manufacturer the fit the stock pipes?
My 6" tips are LCGP Performance, but they're 4" inlet so I used adapters (2.25 to 3, then 3 to 4).
They won't bolt on to the existing tailpipe 'bell' connection, have to cut just past it for them to bolt on.
They were $26 each, polished SS, 2 yr guarantee.

Hey Guys,

I'm thinking about adding the Borla 140308 cat back, or the Mopar P5155280 cat back to my '17 Bighorn 5.7 with the 5'7" bed.

My main question is will the 4" or the 5" tips both fit the bumper cut out? I assume they do, just don't want any surprises. (Pictures comparing the two tip sizes would be great)!

Any general comments of one system over the other are also welcome.

Thanks in advance!
I would like to give you a little information no one will tell you about. From the exhaust manifolds there are 3 inch pipes going through both cat converters then out 3 inch pipe to a what I refer to as a (horsepower gas mileage killer), reduces the two 3 inch pipes down to one 3 inch pipe from this you have one 3 inch pipe going into one muffler then two 3 inch pipes out the back. When you went in for your cat back system they don't I repeat don't remove that POS smashed pipe not fixing nor improving anything.

I have 2015 Ram 2500 4X4 6.4L HEMI I had a muffler shop cut that POS out and installed 2, 3 inch pipes through X pipe 2 mufflers and 3 inch out the rear.

For a quitter system you could install X style muffler, one muffler 2, 3inch pipes in and out.

Without removing that POS you may as well flush your money down the toilet same deafferents.
