Want to keep you all up to date. I'm in the search phase right now. Currently, I have limited bandwidth while operating at sea, but those of you on land in San Diego, National City, and Chula Vista +/- 50 miles, if you could start shooting local companies emails to help me find one that can do this for our rx8 community. I have emailed Extreme MS in San Diego so far, last one sent got failure notice though. We need a company that can get those exact mufflers and can recreate with the same type of steel and weld technique/technology.

Soon as I get back it's going to be put on, might as well do it at a place that can take measurements simultaneously. If I already know which company to use before getting back, it'll save us that much more time.

The sooner we can get these duped the better. I don't care if it is my exhaust that is used first or if N rider89 is able to get these duped first, just as long as they get made ASAP. If you've read my previous posts, you know I was never interested in putting an exhaust on my RX8. I decided to win that ebay auction just to secure the win for rx8club, and in the midst of 1 minute 30 seconds remaining, couldn't sort out who was who and had to sqeeze the trigger.

I got it installed this week. Installation cost was $90, although corrections brought the price to $150. The tips had to be removed and re-welded, since they were lopsided. Also the two mufflers wouldn't line up correctly at the junction, so the left muffler junction was cut off and rewelded. The stock exhaust pipe was cut off to allow it to fit back into the car. I wanted to try fitting it in the trunk, with the pipe extending through the ski slot, but they thought it'd be too big and so I told them to cut it.

The bad news, is that so far the sound it not what I expected. Kind of makes the point of duplication moot.

Should have cut it off on the pipe. not on the muffler side.
Then you could have possibly resell the muffler :-)

No one's asked for it yet, but I am looking into getting a decent recording made. It's the only way to go at this point, let people decide for themselves if they still want the sound or not. Once warmed up, it is mellower than we have been led to believe.

I should be able to get the recording equipment for around $300, as I already have an outboard AD with 1/4 inch inputs. Just need a set of wide-bandwidth measurement mics, short mic stand, stereo bar, 2-ch mic pre with phantom power, and all cables.

Update: Ordered all the gear. It's coming from the east coast by UPS, should be here Friday. Give me a few hours to familiarize myself with the gear, maybe recording Friday or Saturday at the latest as long as the gear arrives on time. I'll post up in the multimedia forum with the sounds when complete. Here's what:

M-audio DMP3 2-ch mic preamp: Lowest I could go and still get decent sound. Should be good with its Burr-Brown opamps.

Behringer ECM8000 measurement mics, 15 Hz - 20 kHz: should be relatively uncolored as they are for measuring in-room frequency response and other testing. Useful low-frequency extension for exhaust purposes.

Other than the above and a few microphone cables and patch cables, I'll be recording with the Ego-Sys Waveterminal U2A USB that I already have. Will connect it to the laptop to record down in the garage, direct to 16-bit/44.1khz.

As you notice from the pictures, it comes with only two exhaust hangers on the back. The OEM exhaust has four hangers on the back.

The exhaust shop relied on just the two back hangers, plus fabricating a new middle pipe hanger to replace the broken one in the photo. In part because of this, over 3 weeks time, the Helix exhaust tips hung lower and lower into the exhaust shrounds. Yesterday the right tip was almost touching the exhaust shrouds, and while revving, possibly touching the shrouds under vibration.

The exhaust had lost a lot of bass and volume, and was sounding almost stock...

I took it to the exhaust shop today, and they fabricated two more hangers, so that all 4 OEM rubber hangers are now in use. They also managed to bring it up an inch to get it off of the exhaust shrouds. Some of the bass and volume have returned since raising it up a bit. I'm not sure why. The right still hangs lower than the left.

At this point most of the problems have been fixed with my Helix. Its probably in good enough condition to send off for manufacturing, but I'm also ready to drive across the country to my new job location in a week. The sound clips and this have pushed back my timeframe and now it is in conflict with my relocation.

I am looking to get a Mazdaspeed exhaust to replace the Helix so that I can send the Helix off some time.
