does kooks or other brand offer y pipe to connect to stock manifolds? with or without cats ? my stock y pipe has 3 cats . would it help to eliminate 3rd cat ? has o2 sensors in front and behind front 2 cats . or eliminate all 3 cats? 2018 5.3 silverado
At this time we do not offer any Y pipes that connect to the stock manifolds. Horsepower gains removing the cats have been shown to be very minimal on stock and lightly modified Silverados, typically netting 2-5hp. Heavily modified and supercharged Silverados due tend to get a much better benefit from cat removal.
