They make numerous race mufflers... Vibrant, Magnaflow, Dynomax, Aero all make small canister style mufflers you could use. I'm just going to end up using a 16" resonator which will deepen the sound.

Boy, if I ended up with 16", I'd be bragging about going deep too!


....takes hat off to Staples

I took those pics... the piping isn't as low as it looks in the pictures. It doesnt hang any lower than the FI exhaust. I can guarantee that.

You could put a resonator before the turbo, but any kind of muffler or cat you're risking debris coming loose for some reason and damaging the turbo.

id be carefull with a lot of resonators on the market too many are packed and the fiberglass can't be too turbo freindly when it starts breaking down and blowing through after a week.

from what I understand resonators don't go on the inside of the exhaust they go on the outside. Maybe I'm missing something

this is a resonator, note the perforated center tube, yeah there's filler in most resonators between the perforated inner tube and the outer shell of the resonator. Think of it as being like a cherry bomb muffler or glass-pack. The resonators you want don't have a filler but they don't effect the sound as much either.

The air isn't going to be as hot as a front style turbo. That's going to put less stress on the resonator in terms of heat, so it SHOULDN'T be too much of an issue. STS recommended instead of using a resonator, use a straight flow through racing muffler.

another thing you can do is use resonated test pipes which do have the resonator on the outside.

I've never heard of outside resonators? :confused:

Are you talking about like what Motordyne offers, their ART pipes?

yeah sorry resonators are always exposed to exhaust gasses they don't go over the existing pipe if this is what you believe suck it up your wrong harsh i know, and filled resonators always break down the "mufflers" on most z aftermarket exhausts are all fiber filled and even on an n/a they get louder after the first week thanks to breakdown.

A lot of the performance straight through's are filled too you have to be careful when buying if you don't want a filled one. they resonators that are y'd into the exhaust are more like true resonators by definition as they are mainly hollow and due to resonant frequencies at like a spring when tuned correctly to produce inverted amplitude sound waves that travel back up the y and cancel some of the sound waves in the main exhaust pipe out. the fiber filling in some resonators acts like a damper and absorbs the sound furthering the frequency range the resonator is capable of affecting.

Kinetix Resonated Test Pipes (350Z / G35) - Modern Automotive Performance Resonator on outside

Stop thread jacking. You are wrong. Move along.

you can still have test pipes with this turbo system.

LOL those are standard resonated test pipes, I don't see any fiberglass packing on the outside.

I still dont get whats going on. You can use the LTH with the system or HFC or TP. There turbo piping starts right after the LTH or HFC or TP. Just like an exhaust setup

If anything, the turbos will suppress some of the sound (not a whole lot, just a little bit more than just having a straight through exhaust).

I've owned resonated test pipes. The interior does have anything other than metal. I owned them with a rear mounted setup, so I wouldn't have put them on if there were any chance of material coming apart and blowing through the turbo.

All the resonators I'm familiar with still have fiberglass packed in them except for MotorDyne's ART pipes. There's a metallic funnel, then under the funnel is the packing. If you don't want the fiberglass, then you would need some type of muffler. They do make racing mufflers that resemble resonators.

Do you know the brand that makes full metal based resonators?

You stated that resonators went on the OUTSIDE of the exhaust piping. That is wrong, plain and simple. Even if there is a resonator with nothing packed in it there will be holes inside the pipe just like 1slow370 posted. I assure you that if you buy a resonator it is not just a piece of exhaust piping with some metal put around the outside of it.

exactly and as kinetix them selves says "we now offer a full stainless straight through converter replacement, but with a stainless exhaust resonator welded in-line." not outside in-line meaning gas flows through them and you may have owned resonators before and i know you had a rear turbo 350, but have you ever cut a resonator open and seen the inside of it? oh and on a side note the oil system on the 350 sts sucks, the return line is to small which puts too much strain on the pump, which is located on the wrong end of the vehicle. I've installed them before and the turbo smokes like it has blown seals until you change the line and fittings and move the pump.

Anyone try this on a 2011 automatic?

Man this thread went well off course, lol. I have been searching for any other Z's with the STS kit, but come up empty. Have they actually sold any other than the one that is on old boy's red NISMO?

They have two nismos and one stock z. They have preorders. Two people only on there list. Numbers range from 450-485 to the wheels on 6-8 lbs of boost. They ran 10lbs and got over 515. Interesting kit with good pricing

I would love to see a STS kit for this car or even another twin kit on the market.

so do we have enough people purchased and said good things about this kit!
man i read all those pages and cant read/write now :D

i would do it. But my compressor and tank is behind the bumper for my bags =[

Finally got vendor pricing. There will be one installed in So Cal by August.

Yeah, August of '12.....:stirthepot:

Next time your in Cali boost vs boost.

On a serious side ..

They will need another car to test out.

What is the price? I could lend my Z.

I'm all out of Z's bro

maybe they can do something my car ;]?

who ever is interested please let me know. The kit will be listed for sale this week on the forum.

I am very interested in this!

My friends think it is a dumb idea, but if it works well the price cannot be beat.

477whp at that price is incredible

That is with 18" rims and long tube headers. I assume it would make less with the regular 19" rims and regular stock headers.

Anyone know why it lost torque below 3000 rpm?

Giant restriction in the intake path? When the turbo isn't turning fast enough, I could see that being a problem unless it had some type of bypass.

nope its restriction in the exhaust system... its called a turbo
