I'm sure it would be very tame. I would avoid ART pipes if you intend to do headers. Just based on my experience. Dyno results I did are in the ART pipes thread.
Video Clip! Recorded with an android phone...but there's pretty much zero rasp. Sounds awesome.

ya if not louder but the video is showing full throttle and idle. Actually my car with the silencer sounds about this loud lol. but its not the volume under throttle thats an issue. the issue with my setup is drone and volume during regular driving. it literally sounds like open headers in my garage upon startup and under normal driving it drones horribly bad. its as loud as my friends R32 turbo with side exit exhaust dump off the headers and thats a 600hp race car. Week one i had been asked to quiet the car down by a cop who heard me a half mile away and i was even trying to keep the rpms below 3k. Silencer in theres no issue with drone.

granted these are videos and you cant really compare volume. this video is the closest ive found to my car. all i hear while cruising is drone and rasp. no other way to explain it. ive had many turbo cars with open wastegates. i had an NA R32 with 3in nonresonated exhaust no cats and cams. none of these cars droned like this. no other way to explain it.

Perhaps Z1 could shine some more light on it, but my thoughts are that with headers like the momentum/Z1's, the airflow is much less turbulent. The sound is very smooth and progressive. I'm very pleased overall with the car while cruising. In the world of singles/aggressive exhausts on the Z, I would consider it very tame while cruising, but definitely louder than my Momentum dual at WOT. It's certainly a frankenstein exhaust with every part being from a different company, but I think I hit the nail on the head with what I was looking for.

That's correct, no silencer. Only sound deadening items are the XYZ resonator, and the resonator on the tomei mid-pipe. It's actually quieter than my Momentum dual, and definitely quieter than when I used to run OEM manifolds.

I placed the order for the XYZ resonated and Z1 test pipes today. Again current Tomei Setup is with the Z1 cats and Tomei ypipe. Ill try to get a before and after video sound clip both steady state and revving and cruising no silencer. this will be with stock headers. I think WOT is irrelevant as we all know the car sounds boss when opened up. Give me 2 weeks

That's an interesting observation as I was going to ask which headers you were running? Z1s?

This thread sealed the deal for me, I'm officially going with soho over tomei.
The tomei just seems like a lot of money for a rudimentary design. I get that it's titanium but there seems to be a lot more r&d/thought into the soho kit. Seeing as how they're the same price (forum vendor pricing ftw) I can't justify the titanium bling factor for a better designed product. I'm going to pair their ypipe/exhaust to my strup headers/resonated test pipe. I am debating switching to standard test pipes since the ypipe is resonated.

If your goal is sheer volume, then definitely go with the SOHO. The tomei matched with the XYZ w/resonator delivers practically zero rasp and the volume at interstate speed is definitely way more bearable than the SOHO.

I would hardly call the Tomei "rudimentary" in design. The exhaust is a great system. I just chose to stick with my XYZ out of the ability to retain the option of a straight pipe or resonator. The titanium also delivers a completely different exhaust note vs. a stainless system. (My buddy is running the full SOHO kit with test pipes. He's the one that won the best exhaust at ZDayz this year). The SOHO y-pipe design looks awesome, but that exhaust (matched with test pipes) is literally the loudest exhaust I've ever heard on a Z. Insane trying to ride down the interstate with it.

I agree with Renfro on this. Tomei has a lot of R&D in this system to produce the most flow as possible however the tone is a little deeper than the SOHO/Momentum. I would suggest trying to hear the systems in person as video does no justice. Just remember the Tomei exhaust is made to produce power while minimizing as much weight as possible.
