Interest Thread: AAM Competition 2.5" H-Pipe + Res Mid-pipe to shorties or stock rear

[Sales@AAMComp]

I'm still not sure why there is so much confusion as to what I'm gauging interest on lol

I thought was pretty clear in the first post

object here is to build an H-pipe and midpipe (or post pipe) to connect to short tails or the stock rear section

why?
1) for those that own short tails, and want to upgrade the rest of their catback, they will now have the option to do so.. will it be loud? you bet ya, you have 0 mufflers of course it will be loud
2) for those that want to upgrade their catback but retain the rear muffler for additional exhaust flow but make it as quiet as possible

the picture above is of our 2.5" true dual H-pipe. The plan is to use this H-pipe, custom build the midpipe or post pipe section, this will include 2 pipes WITH resonators to connect to EITHER short tails or stock rear section because remember these are interchangeable

[Sales@AAMComp]

a stock exhaust system:
headers > cats > y pipe > mid pipe > stock rear section
headers > cats > 2.5" h pipe > 2.5" mid pipe > stock rear section OR short tails

the part highlighted in red is what I'm gauging interest on for the above reasons. Again the picture above is just the H pipe, we haven't built the mid pipe yet

So yes, of course it will be resonated. Last I checked, he wasn't trying to sell this to road racers.

i thought otherwise due to everyone else posting abou a non-resonated version.

my mistake.

I came off pretty aggravated. No offense intended, but I saw like three posts saying the same thing... does no one read the OP anymore?

I have recently been looking for either test pipes, HFC, or y-pipe that gives me a few more horses. I have heard the aam's with test pipes and its awesome.

Just a little too loud for my everyday driver..

Now, I am in love with the short tails. I have actually had people tell me that they think its a GT-R before they see the car. I love that. I think the simplicity of the "bolt on" concept is great. The only downside is going 50 MPH up a hill. Drone like a mutha'...and the fact that the gains are so minimal, if any.

I would like a better flowing system, and like someone said before... If the price is right, i think its great.

I purchased the short tails for $415 after shipping over a year ago. Obviously prices have gone down a little since I bought mine, but even for $415- thats a hundred bucks or so over what it would cost for custom pipes. For $550, you can purchase a complete full exhaust with gains over +15hp. The only downfall--none of the exhausts online sound like the short tails.

If i was able to get gains and the same sound with less drone..i'd be sold. Sorry, I vented.

It doesn't take much to release the drone from the vq37hr. You have to remember the short tails delete your main source of sound control and deadening, there is just no way you can do this, get the sound, and have no drone

the exhaust you're talking about for $500 bucks I don't want to get into this debate now but they are that price for a reason.. some have luck, some don't.

I'll give you an example that actually occurred at the shop today. A customer GT-R was brought in to be checked for an exhaust leak, the culprit was a cracked downpipe, right at the turbo flange. We then tried to figure out what brand it was, the first dead give away was the fact that it WAS a shiny polish finish (typical of over the seas products) well it was shiny, but turned to a bronze/gold/purpleish hue so then we found out it's brand, I won't disclose that information, but that brand sells GT-R downpipes for almost half of what we sell ours for. The buying decision is obvious at that point, why pay 2x more for AAM downpipes that aren't even shiny. Well here goes it

Replica brand companies outsource; whether it be the materials only, materials and labor, etc and we all know where it goes to/from.. so we asked why did this downpipe crack, well we measured the gauge metal that was used, it's no where near the thickness of the stainless steel we use. Not to mention we noticed some rusting on the flanges.. they cut corners and use mild steel flanges.. we use stainless steel flanges. It's tough to compete in this market when stuff like this goes down but we just need to stay loyal and really push the idea that all of our parts are hand crafted by a production team that actually makes a proper wage

Be very careful when buying "cheaper" parts. I do not completely discredit them but I also don't fully encourage it. Some will swear by it, some extremely hate it. I personally fall right in the middle. Hey I rock a CNT downpipe on my subaru and that's an Invidia copy, I'm 100% happy with it. Hit or Miss is the best way to describe it

and that's truly my rant on why there are true duals going for $500

Well put- I appreciate your prompt response and insight.

Regarding the drone- I have learned to love the sound of the car, I just crank my volume up a little more.

I suppose you are right regarding the $500 true dual. & I didn't mean to offend you or the company. I knew something had to be off. I knew they welded differently, but i thought the steel was all the same. I just figured they cost a little less due to the fact that you're not paying for a large name brand..I did think that those who were successful and had good gains benefited. Maybe not for 50k miles but til' it breaks like you said haha...Getting over +15hp with exhaust alone is a great mod. With a price tag of $500 its great. But when you add the potential cost breaking and ruining something, the price goes up.

There was a reason I went for the AAM's and that was for quality, simplicity, and sound.

One of my videos are up on the site. I want to do a more elaborate version. Just recently aquired a few gopro hd hero2's that i will mount and get some quality HD sound.

If this new H Pipe looks good, I am in. & will record videos if it helps any.

awesome! We definitely would appreciate videos. I am surprised at how well the community accepted the short tails with the abundance of videos on youtube, but I can't wait to hear yours! There are already videos of short tails with test pipes and it sounds wild. I don't know how tolerable it might be, but it's obvious so people just love LOUD lol.


To answer your concern on why short tails cost as much as they do.
Here's the break down on that. Sure it might seem like you don't get much for what you pay for when buying short tails but bear in mind: we did all the test fitting for you, these are proven to be a bolt on application, guaranteed to fit, 100% stainless steel, mandrel bend. I can't say what you will run into when you go to a muffler shop but unless they specifically state it's mandrel bent, they are most likely crushing their pipes (mandrel vs crush bent makes a killer difference, both in performance and sound, not that the short tails really make any power) then you ask the question, will it fit? they will have to mock everything up and each time they do it, it's a custom job. You are now paying for a fabricating rate AND parts (piping, tip, flanges, hangers). Is it true 16 gauge T304 stainless steel? And if all these come out to match our short tails and it's cheaper, then cheers to you and the shop. But with our price comes the convenience factor of not having to worry about any of the above, just remove your stocker and slap these on

From your experience, what exhaust component should I add in order to keep somewhat the same sound the car has now?

I don't have $1200 to put down for the 2.5 true dual.
I do however have $400 and I am looking to gain some HP.

HFC? Wait til your H pipe comes out?

so by looking at our dyno plot you can tell a catback will provide you with decent numbers and then HFC's compliment off of that

I can't promise you your exhaust note will stay the same with either upgrades of HFC and/or the upgraded mid pipe that we'll come out with. The tone will definitely get louder, but hopefully not raspier

with the upgraded mid pipe and short tails, you would be looking at similar gains as the above graph, maybe even higher since you won't have any mufflers in the rear lol

the decision really is up to you, just letting you know we are running a special on our HFC for $399 shipped for September, but definitely don't let this be an impulse buy, take your time and I can extend this deal for you. Just don't come to me like 5 months later LOL

I got test pipes from Khoi just today at a great deal. It's great to see a vendor that loves the Z community (or at least this community). I'll be rocking test pipes, an ebay y pipe, and the short tails... once the "short tail catback" is released I'll gladly get rid of that ebay crap... I looked in the pipes and was a little appalled, but I suppose it's just piping.

Videos to come of test pipe + y pipe + short tails... loud videos.

Hi Khoi, I'm interested, but I won't have the bucks until the end of next month. I'm loving my short-tails on my nismo!!!!

can't wait that shipping was quick!

edit: wow skipped right over it. What was wrong with the insides? We just produced another 5 sets yesterday if it's an issue I need to address to the production team before we package them.. I'll go yell at them!
