The pipe that comes off of the cats, what I'm calling our H pipe (some call Y pipe, some call X pipe, depending on design) we already have this designed and produced for the 2.5" true dual

we now just need to make the midpipe section, connecting the rear section (whether it be short tails, or stock muffler) to the 2.5" H pipe. We would definitely have to throw some serious resonators on there especially for those running the short tails already considering they have no mufflers lol

Now if this can work with the Nismo versions as well....I will be VERY interested.

There has been interest in the Nismo owner side to replace the stock H pipe, would this work?

yes, according to a few threads, the rear sections are interchangeable (between nismo vs base/touring/etc) which means our h-pipe + midpipe in theory should bolt up to both nismo muffler or non nismo muffler

I'm interested to see how you guys go about resonating the whole thing; the product would ideally serve to create a good sound in people running the stock muffler or those running the short tail pipes. I'm also curious to see how it affects people who have the stock cats, HFCs, or test pipes.

Also, if I am reading correctly, this is essentially the same thing as the true dual you guys sell; it will convert the Y pipe/H pipe/whatever into two pipes (given you actually use the H pipe from the true dual), which go down through the midpipe, into the short tails. This is essentially the true dual product using short tails instead of resonated cans.

I understand you're only gathering some mild interest, but why not simply "bend" the current 2.5" true dual AAM sells to fit the short tails? Mind you, I'm only an engineering student, so I don't know of any issues that would arise from such a jury rigged solution. To solve noise issues, you could vary the placement and size of the resonators until you reached a solution.

Either way, I'm also sort of interested in an ETA, if you can provide one. This will probably be the only midpipe replacement on the market for the Z; G owners (especially the X, AWD variant owners) would kill for something like this, if they didn't want to do a catback.

I feel there would actually be more interest if this thread were placed in General Discussion, although it might not exactly go by the rules... it's just that nobody actually reads the tech area all that often.

Any pictures yet of the H...X....Y....pipe?

Khoi can't post because his account is currently the only active AAM account, but it's not yet approved with sponsor status. He can't post anything right now, so we'll have to wait a bit.

I'll snap a quick picture in a second here

I'm back! haha not sure why my account became inactive anyways thanks for your order your test pipes shipped out this morning! Don't go deaf too fast on me now :tup:

here is a glimpse of our H-pipe that we currently use on the true duals. This is what we will be piggybacking off of to create the mid pipe

to answer this question, our current mid section in our true dual is bent to fit the rear sections of the true dual only. It would make most sense to rebend the true duals mid section to mate to the stock exhaust/short tails and then build the true dual rear sections from there but it sounds like we are going the harder route which we will discredit the true dual completely minus the H-pipe

the test car will go up hopefully in a few weeks and pretty much what's going to happen is we will bolt up the H pipe (from the true dual), bolt up the stock 370z rear muffler and build the mid section from scratch to connect the two

So you're basically just taking the hard way.

Sounds fine with me, as long as the hard way doesn't end up with a massive price increase for some steel piping.

Keep us posted for updates. (I'll try to preserve my hearing in the meantime.)

since drone was some of the intitial issue, will this new one be resonated?

I vote for resonated pipes too. If this works on a stock 370Z connecting the cats to the mid pipe, then this might be a solution to my warped Sunline H pipe.

no way i'm uprgarding to this if it's not resonated

If you read the first post, Khoi clearly mentions that it will have to be resonated for both stock muffler and short tail users, because as short tail owners already know, they're extremely loud compared to the stock setup and even most aftermarket catbacks.

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