Cat deleted alone there’s no real power gain from them. But the sound is night and day. Significantly louder and more aggressive. These only came off to be replaced with an ARH long system with my Cobra Jet build.
Looking to sell my cat deletes. Manifolds not included. Located in DFW, TX or can ship on buyers dime. $150 + ship. Guy I bought these off of has rewelded the drivers side flange, I’ve had an O2 sensor bung rewelded. $650 retail. Overall good shape.
I have a set of ARH on order but huge lead time with most header companies. Looking for a set of either Kooks or ARH headers with offroad connection pipes. Located in DFW, TX.
