Since they make them in house (per Mike) I'm sure it'll be easy for them to customize it for your specific needs..........

I wonder if there is some resonance caused by the difference in secondary pipe lengths.
For some reason it sounds very loud inside the car but very quiet outside the car. Im guessing not enough sound deadning material was used?

I believe on this forum SRT was the first to showcase a exhaust with this kind of design

or at least the 1st to post a thread about it

looks good can't wait for the dyno on Thursday.

I hope you make 40whp and 20wtq jk jk don't want to turn this thread ugly

haven't heard it from outside the car yet. Maybe it's quieter outside than I think.

Yeah it is, the alignment guy drove it today and i have to say it was nice and deep but not loud at all. I think its our interior that is crappy and amplifies the sound.

If it's quiet outside and loud inside that means it's resonating. I wonder if they could fix that with a Helmholtz resonator.

If it's a cat-back system with the stock headers, wouldn't the cat-back bolt on after the downpipe and the small factory resonator still be in use? (I assume that the small kind of honey-bun shaped item located by the down pipe is a resonator?)

In the first picture in the link, isn't that a resonator at the far right center of the picture? http://www.ft86club.com/forums/showthread.php?t=12866

It's a band stop helmholtz resonator. They used them on the Fozzy's and Legacy's that ran quasi equal length headers as well. It works to cancel drone, but it assumes the pipe diameter and harmonics of the factory system. How big is this CBE? 65mm to dual 65mm I'm guessing.
