So I’m going for an off-road set up. I’m looking at the only mid pipe offered by Kooks which is Catless the only problem though it says it’s only 05-15 will this fit my 2017 Challenger RT? I see it has a 3’ collector but a 2.5’ that will plug up to the “stock exhaust” will it fit my 2.75’ Borla

Model #31003100

I see those (Model #31003100) are listed for the older models. They updated the exhaust on the R/Ts to a 2.75 for your year so more than likely those will be too small. If they list the product for an R/T (2017) setup they will have the correct setup for the stock exhaust, and the Borla is setup for the stock exhaust direct replacement so that configuration will be the same as your stock exhaust.

If you still have your stock exhuast you can measure the ID.

Thanks for the info Steve. You wouldn’t happen to have any kook off-road mis pipeset with a 2.75’ outlet

I can’t find any Mid Pipes from Kook that has a 2.75’ only ones with that is the 6.4s would those work?

Looks like Steve White Motors has you all set. You can't go wrong using them either.

Good Luck with the setup!

the usual sizes, R/T will have 2.5 inch cat back, some of the base 2015 and up R/T may have the smaller 2.25, the SRT, Scat, Hellcat are 2.75

 

[stevewhite]

there is no 2.25 mids from Kooks, and the 2" long tubes are totally un necessary unless you have a huge displacement high boost engine

I have a 2017 R/T and it came with 2.75' Pipe Diameter I also upgraded my OEM catback to Borla Ataks part #140714 so the ones you listed will fit? You confused me with this new post.

 

[stevewhite]

could be an option on 17 and newer, do you have active exhaust???

 

[stevewhite]

the Kooks long tubes are the same for 5.7, 6.2 or 6.4, the mids is what changes, exactly the same, except for the output size, 3 sizes available 2.5, 2.75 and 3.0 which as a rule only work on the Kooks cat back (Hellcat version)

there are two primary size available 1 7/8 and 2" however would not recommend 2" unless stroked large displacement with lots of boost

the long tubes also come two ways, with pressure sensor port for newer models and non pressure ports for older, we only stock the new style
