Got it done and running today .. I have to go gas up and take a ride .. Sounds nasty !!!! ...IN a good way lol ... I'll report back later ...

Well I got to take a ride and this thing is loud !!!! Putting around it is fine but blip the throttle and it will peal the paint off the cars behind you .. I'm so glad I didn't add a H or X pipe because it would have been crazy loud ... I'm also happy I left Cats in it ...I could not begin to think how loud it would be with no Cats and a x pipe ..

I didn't get to stand on it and ring out the gears ( too many cops around ) but the Bama tune feels real good ... Nice and smooth , great idle and snappy throttle .. No CEL light .. I didn't feel any loss of low or mid range power that some have talked about .. The car feels like I pulled the stock 5.0 motor out and installed a built 5.0 motor ..I have no clue how much HP I picked up with the headers and the new tune but very I'm happy ... I'll hit the 1/8 mile Track next week for a little test and tune and I'll find out just what it picked up power wise .. If all goes well at the 1/8 mile track I'll head down the 1/4 mile track next Thursday night ..

I did BBK LT headers on my 2011 V6, and I had to use some O2 sensor extensions that came with the headers and x pipe. Do these kits for the 2015 GT require you to use the O2 sensor extensions? I had trouble with the BBK ones, and would be much more interested in a set of LT headers if they don't need any extensions.

Yes you will need O2 sensor extensions for the front 02s .. But they come with the headers and are plug and play ...

Track numbers were not great ..The car slowed down big time ... Waiting to get it on a dyno and check the tune and see what the numbers are ..

I used SW Power series 1-7/8" and did not need to use the extensions that were supplied. I rerouted the factory connections and it reached just fine, I have an auto so IDK if it's the same for a stick.

It wont reach in a stick. The passenger side forward most o2 sensor needs an extension. All the others reach just fine. At least that was the case in my Kooks install

yep, auto is good

So much mixed gains with this new platform. It's been a while since I've had a mustang, but it seemed so easy to get power. Now I read some people are spot with mods and some are not getting positive gains.


Want to mod my car, but hard to buy parts when I read about so many going slower after mods.

I will keep reading.

Well dyno numbers are in ... Dyno jet dyno STD scale 401 HP and 347 TQ ...SAE HP was 390 ... A/F was 14.2 up to 14.4 ... Made one pull and stopped after seeing the A/F ratio ... This was just a dyno run , no tuner or tools on sight to remap it ..It was just a dyno pull to get a base line ..Looks to be down about 35+ HP from what it should have ..

Good news is I now know why the car ran slower at the track... :( Bad News is I need to spend more money.. :(
