I’m upgrading to a BTR Stage 2 Truck cam in my 2011 Tahoe (5.3). The entire exhaust system on it is currently stock (has cats). Now I know I can run the cam with stock manifolds but will lose out on the full potential the cam has to offer unless I switch to headers. I have shorty headers in mind because this is a daily vehicle and not a race truck where long tubes would benefit in mid to high RPM’s. Shorty’s just seem like a better choice given it’s a daily driver and I won’t be balls to the wall redlining to benefit from long tubes. I understand when it comes to modding a vehicle there’s things you have to jeopardize to make it work. However this is my issue, If I put shorty headers on with my stock cats it will probably ruin them in no time. Which leaves me having to go high flow cats or at that point catless because if the stock cats aren’t on then it won’t pass inspection. How are you guys getting around inspections that are running headers? I know most will say just go catless but I’m trying to find a way or setup to make this thing pass inspection while still being able to run headers for the cam to benefit.
