Ace 4-2-1 Header

[X Factor]

I don't have video, loved the Nameless axleback before the header install, not so much now.

My ACE powered NA car still much faster than anything this sunday :

The other cam. Catching a Cosworth supercharged/E85 GT86 at some point :

Replaced the Nameless axleback with the Greddy Supreme SP catback this weekend, sound is great. It's quieter, no drone, nice deep tone.

Did the ace header increase the highway drone or was the setup just too loud? I have a nameless axelback and was planning on getting the ace header but I'm worried about drone on the highway. I was thinking maybe the JDL ultra quiet front pipe might help. Did you happen to do a before and after video when you swapped exhaust?

The combination of header 350, stock front, stock midpipe and Nameless axleback was too loud for me and too much drone. I don't have any before video, I'll try and get one of the current setup.

The Fujitsubo double resonated front pipe is an option as well.

I've found that the 350A with the ACE FP paired with the resonator from the Perrin cat back in the mid pipe with the Apex-i Evo RS catback is a very nice combination. No drone at all, and nearly as quiet as the OEM cat back with everything else being equal.

I'd rather not go catless. I wish someone still made a Helmholtz resonated and catted factory fit front pipe.

I find that hard to believe unless you're strictly talking about cruising and not under acceleration.

I'm running 350B, JDL Ultra Quiet FP, and Corsa Catback and while cruising isn't loud, under acceleration can be obnoxious. I also have an ACE FP and switched to the JDL because of how loud it was.

I'm running 250B, hks dual resonated front pipe and greddy supreme sp and I find it very quiet cruising and pretty quiet when accelerating.

Definitely crusing, but even under acceleration it isn't very loud IMO. I've run the same header and FP with a Tomei 60R, which is the other end of the loud spectrum.

The current prototype on the CSG BRZ is very promising. It passes the "Laguna test" (90dB at 30 feet, 30 degrees offset), and has no cats.
