But one thing we do share (392/hellcat) in the exhaust is with the active exhaust valves to make it louder in drive modes.
If you are going to change the exhaust I recommend a Corsa and have your shop cut off the section with the flaps and reuse it on the corsa as per the instructions. Before I put the corsa on the hellcat, I got another Borla atak since I had one on my Jeep. But the jeep didnt have those flaps and this was my first time having that .
Big mistake. I bought the borla that had their version of the flaps built into the exhaust, the ************* squeaked like crazy EVERY time I pressed the gas. So I contacted borla and they offered me a full refund and paid for labor as well. They were cool in that sense but the product wasnt good.
So I went and got a corsa and reused the oem flaps like it said in the instructions and all was well!
Theres the video showing the squeak I was talking about. (Side note, I wonder what mf’er left me a thumbs down? Lmao)
