Do you lose selectability of the amplitude?
If you do....not for me.

I would want the headers but no other exhaust changes. I think the FPC sounds much better with equal length headers. More like a Ferrari as I originally expected the engine would sound.

I think equal length short tubes will be the sweet spot. I'm so over long tube headers on modern cars but if there is an equal length header offering that comes out and I can still use the factory cats and it gives a snarly FPC growl, count me in.

Great numbers - I'm definitely interested in the headers, but will watch to see if any issues arise with CEL's and harmonic resonance. I would love to hear these in person too.

Why? It only takes a couple of days and the patience of Job to install them.

It's only painful once.

Emissions headaches and sound restrictions at racing events. If I go long tubes, I'm going to break sound restrictions for sure. It's not the install, it's the all the residual challenges after the fact. If I didn't have to worry about those things, then yeah I would absolutely do it.

I was being facetious. But, I gotcha.

Here's to hoping that I pass the sound restrictions at Atlanta Motorsports Park!

Yeah...about that.

I am worried about that too :shrug:

With all the testing getting done, anyone grab a sound level meter?

I put together a Cleveland swap in a Fox Mustang with long tubes and I realized that I'm no Job.

We didn't get sound levels, but I think its good to go. My '12 car is LOUD and it passes at AMP. It's actually more quite with the Kooks mufflers than the OEM mufflers with the headers and x-pipe.
