DocSnickers

I wanted to get some more input on the subject of headers on the 2013 Mustang GT's. I have talked with a few guys locally that have said swapping headers does not increase performance much on the 2013's. Most of them have been saying the factory headers on the 2013 yields more of a horse power increase with a better mid pipe and a good axel back or cat back setup.

My question is does anyone have any numbers to show performance gains to support that the factory headers are the best way to go? Or numbers to show that after market headers will perform better.

I was looking to go with a complete exhaust system from Stainless Works. Was looking to install their headers, mid pipe and muffler system. If I am not going to see a huge performance difference with their headers I am just going to opt for the mid pipe and and mufflers.

I have a buddy making 981rwhp through the stock headers

Wow, that is pretty good. Guessing it's massively supercharged?

I'm also curious about this. I read conflicting opinions about them. But by not buying them i'm half way to a Nitrous setup.

Buy the nitrous. You'll gain way more then you ever will with headers

Not interested in Nitrous or supercharging this Mustangs, just want some hard facts with stock headers vs aftermarket brands.

stock are very good

I know they are good but I am hoping someone has some dyno tests that show the actual increase in performance.

Check you tube there's lots of dyno videos of 4xx hp cars with no headers.
