One thing I will mention that was the biggest hold up in the installation was that I did not have any nuts and bolts that would mate up the over pipe to the front pipe. I’m not sure if my stock hardware was different for some reason, but nothing fit and there were no parts in the hardware kit that came with the header that were meant for that. A Home Depot run was necessary to get these parts. I haven’t read about someone else having this issue, so I don’t know what was going on in my situation.
Securing the header nuts to the engine was a little bit of a challenge for me and there was very tight spacing but you just have to figure out what technique works for each nut.
]After installation, the header was rubbing/vibrating against the metal skid plate in 2 spots, it was extremely loud. I hammered down the 2 spots but it still vibrates very noticeably at around 5,000-6,000 RPM. I’ve been too lazy to hammer some more but this is definitely a fixable problem.
You could just get a shop to do the installation and forget about all these problems but what’s the fun in that!?

Is this normal for the header installation? Per the CSG product page, "- Modular with OEM Front Pipe back," so I wouldn't expect any problems mating the ACE OP to the stock FP.
Are the rubbing issues with the skid plate something that can be avoided by tweaking how the header mates to the FP and engine, or is that something that's prevalent in all 350 installs?
