American Racing Headers!

I know there are threads on these already but I was wondering if anyone has these on their 5.0?! I have a 2012 GT and I am considering these or maybe kooks long tube headers. I also will get a catted x pipe and already have the outlaws axle back. I really am curious on what the main difference between the 1 3/4" and the 1 7/8" headers are. Any help would be greatly appreciated! Thanks in advance!

I now see that. Sounds like a great set up! Wish I didn't have emissions

7/8 is good for N/A but is far better when you add boost. so if there's any possibility of you getting boost might as well get the 7/8

If you are staying NA for sure go with 1 3/4. If going FI or alot of spray latter on go 7/8

Thanks for the help so far! I plan on keeping the engine pretty stock for the future so may just stick with the 1 7/8". I'm assuming the sound will be the same either way. People have told me the American racing headers fit nicer than the kooks.

They're easier to install than the Kooks. And again if no F/I is in your future stick to the 1 3/4.

Would having 1 3/4 LT headers be a bad thing with FI? I get that 1 7/8 would offer better flow with the larger piping but I can't see the smaller piping being a particular problem? I'm curious with the intent to go FI and having 1 3/4 is all.
