Beautiful Headers, But Be Warned!

I decided to completely rebuild my 2013 Mustang GT's rear end and since we were having to take the exhaust down to get to a lot of the parts, I decided to do the exhaust as well. The headers themselves are gorgeous, the ceramic coating looks wonderful, and the bends and shapes of the pipes look phenomenal. Viewing the exit ports on the headers, there are four exit ports, so each tube has it's own port unlike the stock headers that feed the four tubes into two exit ports. I have access to a lift and engine jacks at work and my stepdad (who has rebuilt many Mustangs) and I started to strip the stock headers off, we decided to just reuse the stock bolts on some of the areas just for the ease of getting them on and off. What we found out, the threads on the bolts that come with these headers, DO NOT MATCH THE FACTORY THREADS. When we tried to install one of the bolts that came with the headers, the BOLT STRIPPED THE CYLINDER HEAD. Luckily we had the equipment to retap the hole, and found another bolt in the shop to use. If you can, just reuse the stock bolts, or at least double check all bolts to make sure that they are the exact same thread as the stock bolts or you will be in for a world of hurt. Other than that, they sound glorious when you fire the car up with open headers. Almost tempted to not continue putting up the rest of the exhaust. But due to the issues caused installing them, the rating is lower. And you will need a lift for this, or have someone install them who has access to a lift.
