This exhaust is hot off the press and we'd like your help to get the word out! In an effort to help with our marketing of the AAM Competition 3" True Dual Exhaust System we would like to extend an offer to the first 10 people who purchase this exhaust. In exchange for pictures and/or sound clips that we can use on our website & in our marketing, we will discount the first ten exhaust systems $300 off of MSRP for both the 370Z and G37 version of the exhaust.

The AAM Competition 3" True Dual Exhaust System is a truly remarkable exhaust system and we hope this marketing discount plan benefits both you with an extra discount and helps us quickly get the word out and build a collection of installed exhaust photos & sound clips.

There is an extra piece needed for the G37 because of the extra length. Unlike our 2.5" True Dual that has a straight piece to make up for the length, the 3" extension for the G37 actually has a bend in it.

Sorry if this is out of place, but I've asked before and got no answer.

Does anyone know if I can run the OEM nismo catback (not s-tune) with the non-nismo aam short tails I have on my tour/sport z? I know their is a difference between the two short tails. Just didn't know if it was because of the bumper differences or what?

Must be a pretty tight fit then. Thanks for the details

Meaning you want to use your Nismo H-pipe with the regular Short tails vs Nismo Short tails?

Yes sir, the nismo H-pipe and midsection and the regular short tails I already have on my (non-nismo) touring/sport z.

I think the regular short tails will do fine since you have the regular bumper.
I have the AAM Midpipe and its the same as the Nismo H-pipe (just bigger diameter). Paired with the non-nismo Short Tails.

The only difference between the standard Short Tails and the Nismo Short Tails, is the tip section. If the Nismo Short Tails fit, the standard will also fit.

Thank you sir, I was looking to pickup a used nismo exhaust and pair it with the short tails I already have on.

Looks great but I think the exhaust would look better coming straight out of the back instead of at an angle. I m guessing the flanges are 2.5" expanded to 3"? It's nice to have other options on the table that are Available and ready to ship!!!

Sound clips would be nice!!!!

It comes out angled because of the rear suspension. If it was straight out, the bends before the muffle would have to be so extreme that it would disrupt flow. In the first stages of R&D, while we were designing everything with CAD, we tried to see what would give us the best performance, while looking as nice as possible.

Everything is 3", so if you have 2.5" test pipes, they will bolt up, but the flanges won't match up 100%. This isn't a concern as the gaskets will make sure there isn't a leak. If you have 3" test pipes, everything will match up 100%.

Sounds clip will be available very shortly, I promise! :)

22WHP on a NA 370Z? Wow

Yeah I got a laugh out of that as well but choose not to comment...:rolleyes:

We took a showroom stock G37S and dyno'd it at 290WHP. Added nothing more than this exhaust and dyno'd it at 312WHP.

We were just as amazed as you guys! When we did an actual dyno tune, we got even more horsepower out of it.

what dyno did you use? most people don't see anything close to 290whp stock :ugh2: :confused: your numbers already sound 15-25hp to high for stock……..

who cares what stock made on other dyno

Gains is what you should really look for not HP dyno vs other dyno

but if the dyno is reading high to begin with then the numbers will be off from the start

The dyno is measuring what it is supposed to. The difference between the baseline and successive runs is what counts. Who cares if it is a dynopack, dynojet, or mustang? Leave it at being a tool for measuring the results of a given modification..........

One thing is for certain though........on a NA VQ, it will loose bottom end in a trade off for more mid and top end.

</offtopic>

My first dyno was on a dynopack. My successive dynos were on a dynojet. A baseline was done each time and the result of tuning (or whatever) were reviewed afterward.

</end offtopic>

I understand this as I have uprev and tune on mine. but 290whp stock seems a little to high IMO :ugh2:

I aalways consider vendor products with caution. We all know there's gotta be hype for the "new and improved" product which seems similar to the others already out there. I certainly hope you get the advertised numbers. Just research the company.... and take it from there.

Do they come with burned rolled tips?

I feel you, but I don't even look at those numbers like that anymore.

I usually don't defend companies selling a product on the forums, but AAM has been around for quite some time. The offered a 3" R-Line exhaust before and it was pretty beastly. I would have had the R-Line IF I didn't already work the deal to acquire the Fast Intentions 3" offering.

These mufflers aren't angled downwards like the fast intentions, are they? I'm lowering my z 1.5-1.75" and would not like to scrape them

Exactly my first thought when I saw the fitment on G37 coupe. I would scrap the hell out them

I must say that I am interested in this, as well as the 2.5" True-Dual and the S-Line Midpipe with Short Tails. I haven't really made my mind up at this point, I'm hoping that these sound as good as the other 2 systems (kind of hard to tell in the G37 video).

As I understand it, AAM previously had a 3" exhaust but is no longer available partially for being too loud on NA cars? How will the sound levels differ on this new model, is it quieter due to the resonators?

I love the way the Short Tails sound in video clips but I am thinking they may be a little too noisey coming home at 2am after a night out and going to work in the morning. The 2.5" True Dual is probably just fine sound levels for me, if the 3" True Dual fits in-between the Short-Tails with Midpipe and the 2.5" True Dual, that is probably a-ok but I may be hesitant if it is at short-tail level or louder (since most 3" exhausts are pretty darn loud).

I don't plan to go FI any time soon but judging from the dyno chart, it doesn't look like low-end torque drop off is too horrible. I suppose if low-end torque was a high priority I wouldn't have gotten a 370Z in the first place.

A buddy up here in the Toronto area has the old AAM 3" on his GTM tt z34 sounds :yum:

THIS X1000

Dynos are tuning devices, meant to measure gains, not actually measure WHP

a dyno operator can make numbers say anything you want them to

On sale on their website $1595.

Great new product since there aren't many 3" exhaust systems out right now but I feel like the muffler style on the 2.5" system is cleaner looking

We just put one of these on a convertible last week and it sounds incredible with the top down. Hoping to get him to come back soon, so we can get sound clips and more pictures! Here are a few pictures I snagged with my phone before the car came off the lift.

I'm still interested in this exhaust.

How do you think the sound volume compares to the short-tails? I am kind of hoping that this fits in-between the short-tails with s-line mid-pipe and the 2.5" true-dual in terms of loudness but I guess since it's 3" it has me a little skeptical that it will be softer than a straight-pipe/no-muffler exhaust system.

Are you still discounting $300 for sound/video clips, or have you sold enough already?

I have a digital interface for my phone where I hook up a studio mic for high-quality sound recording, (works great on the go when I cant use a mixing program on my computer all the time), it would probably be pretty neat to test it out on some other "musical equipment" :D

I also see on your site that you have a new axle-back exhaust.

Similar questions,

any rough idea how much power that will make with the s-line mid-pipe in conjunction to your other exhausts as well as estimates on loudness?

Thanks again.

It sounds awesome. The short tails mated with the s-line midpipe is just way too loud. That was one of the main reasons we went ahead and created our axle back.

As far as volume goes, the midpipe/axle back combo are very similar to the 2.5" true dual, but with a slightly deeper tone. It definitely helps hide how "raspy" the VQ37 and eliminates drone. We have quite a few bit of samples for sound clips, but I will gladly extend the $300 off to you for sound and video clips.

The s-line midpipe and axle back will make almost the same amount of power as the midpipe and short tails. Their is only a 1 or 2 WHP difference between the two. A lot of time went into the R&D to make sure it flowed well enough. The G37 that we tested the s-line midpipe and axle back combo on sounds fantastic. It's still louder than the true duals, but not as loud as with the short tails. The axle back basically helps keep the drone in check that some people experience with the short tails.

I would say sound level wise, they follow this from loudest to "quietest"

Midpipe with short tails (very loud, raspy)
3" true dual (just a tad quieter, but not raspy or droney)
Midpipe with axle back (quieter, slight rasp, no drone)
2.5" True dual (about same volume, no rasp or drone)

pretty curious about this....i just always hear 3 inch exhaust is mainly for boosted cars,and bad for NA cars..

looks freakin awesome however. sound clips?

On the dyno, we got the most gains out of the 3" exhaust. Yes, they're great for boosted cars, but that doesn't mean it's bad for NA. You will still see gains, especially when paired with test pipes.

Here is a short video we made. We are working on getting more samples.

Yes its apples and oranges, but high horsepower/high compression NA Honda 4cyls such as a K20a or a b18c5 make great gains with 3" exhausts vs. 2.5" and we're talking about 1.8 and 2.0 engines.

NA applications are always able to make better power with more flow in, more flow out, and more RPM.

Any perceived "loss" of power on the low end isn't really relevant. If I was doing a serious NA setup, shorter gearing would be a high priority anyway.

Can I still get good gains and better sound if I did axleback with stock nismo exhaust or is flow too restricted from the stock pipes? I like how high the cans are but I am not sold on the angles coming out from the bumper. Thanks for the info
