Anyone have the Sorcery F1 2-1 Exhaust?

Recent videos of the Taitec GT-009 Racing Exhaust have convinced me that it is the best sounding exhaust for the NSX.

However I'm not sure I can live without a rear valence, cat-delete and asymmetrical layout, but I'm wondering if another 2-1 exhaust would have a similar sound.

Anyone have clips of the Sorcery F1 and have any more info on it?

Hmmm don't know a conventional style exhaust with that sounds.
I have seen and heard TaiTec single exit exhausts in real life they are special to say the least it changes the look of the NSX quite a bit.

It's of course up to a personal taste but i think most NSX owners might agree it makes it look boy racer/ricer civic, but to each his own and we should respect that.
 
I just went through designing a similar system for mine.

It's NA2 headers, (2) 2.25" Magnaflow cats to a 3" Flowmaster collector. Then, it goes to a small (8" long), straight-through muffler and out the center of the car. Probably the best combination of lightest weight, free-flowing, inexpensive, and quietness that you can get in an NSX exhaust.

There's no doubt the Taitec sounds like that with cats removed after listening to mine. However, I wanted to run cats and have a center exit. The cats cut down on the 250Hz frequencies (pretty much what you were listening to in that Youtube video), and the longer pipe I have (to make it exit the center) makes my exhaust more mellower-sounding. That's OK with me.

Also, note that my setup has an extra 2.25" black pipe sitting at 90 degrees to my 3" pipe. It's there as a resonator and doesn't restrict the exhaust flow. If you just have a straight pipe out the rear (as I tried), the firing frequency of our engines around 2K+ RPM makes a loud droning noise in the cabin (~100Hz). This is from 2k-2.5k (where I cruise at in 5th gear) and is VERY annoying. That resonator I put in is capped at the end and reflects the 100Hz waves to cancel each other out. No more drone, no exhaust restriction, and just a little more weight.

I'm still playing and re-arranging this - I'm learning to weld (need to get rid of the clamps) and then I'll build my diffusor when I'm happy with the sound :cool:

When I get some good exhaust sound clips I'm going to make a new thread explaining how I cancelled the annoying resonance. Involves sampling the exhaust with a PC and microphone, a sound-analyzing program that can do Fast Fourier Transforms :biggrin:, and a little calculation of quarter waves to determine your tube length....

Your exhaust looks promising Dave,

Let me know if your Fast Fourier Transforms can help you design one that can have a meaty low end burble at idle, aggressive midrange and a loud straight pipe like high pitch top end, while avoiding the cruising drones around 100Hz!
