Everything fit great except for the Y-pipe! The y-pipe didn’t align with the manifolds and created a small leak. My buddy and I tried numerous times to get it to fit but it just didn’t. So now I have to order a separate y-pipe from a different company. Besides that, it said if you order within the next 8hrs it would arrive in 3 business days.. my package didn’t arrive until 6 business days later. Other than that, the rest of the contents in the packages worked well
