Full length header test

I have a few others posted. Also inside the car. But remember these were all in sport mode. In normal mode it's near stock quiet.

Sounds crazy loud and raspy. Post up some vids closed.

I was thinking another set of active mufflers for a cleaner sound. But only magna flow has these now I think.

Does any of the exhaust fumes or smell get into the cabin? Asking bc my buddies catless GT does and that's the only thing stopping me from catless.

Why in the world would I put resonators on it?

After installing longtube headers in my 2011 the blatty/raspiness was too much so I installed resonators/mid-mufflers to clean up the sound. Volume and tone stayed pretty much the same but almost all of the raspiness was eliminated.

I haven't notice any smell while driving. But if I stand behind it its very faint smelling. Doesn't bother me. But again I'm a mechanic lol.

I removed my resonators and it did get a bit more raspy, but I like it

But you also didn't have active mufflers or a flatplane crank then either

Any added drone in the cabin.

Yea the stock catted exhaust sounds good with no resonators.

Lethals car is full of rasp with the midpipe install and they have resonators. Much louder than stock too when closed.

THIS JUST IN!!!
Dyno pulls at Watson tomorrow at 1. I'll be doing dyno pulls to compare the stock baseline to the ARH long tube, off road X pipes and stock active mufflers. No other mods have been done to the car. 171 miles on the odometer. 93 Sunoco. Once the header dyno pulls are done, I'll install the Lund Flex fuel tune and run it on 93 octane. I'm not sure how much time will be had to install the JLT. I also will not have a chance to use E85 because Watson is squeezing me in to get this done because they are in a rush to do the cobra jets. I'll do E85 dyno pulls at another time. Besides I also have a 1/4 tank of 93 yet to burn off

I have no idea how to post a link on here, but I will post dyno videos on YouTube tomorrow.
Baseline 100% stock with 93 and 168 miles on the car was 454 hp/ 370tq

 

[bdub85]

What type of dyno was the baseline done on?

 

[Voodooo]

Dyno jet.
John told me of all the gt350s they dynoed for ford they are all within 1-3 hp of each other.

Curious to see your final numbers. Your car sounds amazing with the headers.

I will be getting mine tuned in a few weeks.
