Yep...will try post soon. I posted one pic on the new nismo owner intro thread yesterday!

Great opportunity to have each section available...for those to inch up to a sound they like or can tolerate!

I have AAM products, and I support their products :tup:


Long tube headers > resonator box like motordyne > 2.5" mid pipe > short tails

^^^^

this however is beast mode

Thanks for your support sir! :tup:

I thought motordynes xyz pipe is actually a Y-pipe with interchangeable parts at bottom of the Y? this in turn doesn't make it a true dual. With our H-Pipe we would be true dual all the way back, which would probably be super loud but we'll see how it goes!

edit: right now our current true duals run 2 12" vibrant resonators. we might need to bump the size on this prototype especially for the guys running short tails. I think the best of both worlds would be to have the option to run with 1) no resonators 2) 12" resonators 3) 18" resonators, with 3 different price points

Yes please-

I'd like to hear how loud it is..

Thank you 370zPurist. Also, your old comments at the beggining of this thread cracked me up-

there are a few videos of short tails with test pipes on youtube already. Sounds super sexy on video but I'd advise against daily driving it unless you love loudness and attention lol

but yes in for video when you put it on :D

Khoi, where are these videos you speak of? I only know of that one I sent you in a previous comment. The monterey blue 370 with invidia test pipes and short tails..

check out this video, he mentions a straight exhaust but not sure if this is on stock cats or what. He has a lot of videos with this set up

Not seeing anything- try again? Is it the blue one from texas? If so, i believe he deleted the resonators as well

yes it is, his car sounds WILD haha it's very impressive but probably very loud in preson. I thought there were more videos but I guess not :( guess we have to wait on 370zpurist haha

edit: ok after looking at one of his other videos he does mention he is on stock cats, just upgraded Y pipe and resonator delete

This one sounds like it would as a daily driver haha--

Also, check out this short one... sounds beefy

I'll be on the test pipes and Y pipe this weekend. I don't have a particularly great camera but it should be accurate to sound, just not the volume.

I'm glad to see more interest, because I am really looking forward to this.

The only problem with running three options is that I'd love to run each one for a week to see how I like them, I do want loud but I don't want insane, 100+ db sound that ends up giving me three tickets on noise violations. Plus, carrying that much product would probably increase the end price of each product. Not to mention I'd have to buy all three sections at some point, and if I like the non-resonated version but then try the 12" and then the 18", I'd have to sell the subsequent one to try the next one... then I'd have to sell the 18" to go back to the nonresonated version! I'd love to test these out too, but I don't exactly live very close to Maryland, not to mention it's going to snow here not that long from now.

I would suggest something like the motordyne Y pipe which has the interchangeable rear sections and incorporate those into the midpipe or H pipe, but that introduces more flanges, gaskets, and other things that can break... not to mention more development cost.

Decisions, decisions.

the motordyne set up is great if you run the stock midpipe as it Y's together. Our H-pipe ends with 2 outlets not 1, making it a true dual set up. If anything the resonator option should be 18" for those running short tails, then no resonator or 12" resonators for those that will be running the rear section. But these are all ideas and I appreciate everyone's input!

so with that being said there will be TWO pipes coming off the H-pipe as pictured before. the midpipes will have TWO resonators (1 on each pipe)

I could do the 18" section for the street and swap out for the nonresonated for track/autoX use. Would be convenient.

I meant that you could have "bolt on" resonators along the same vein as the motordyne, that is, you have a removable/interchangeable section(s) on the H pipe. Take off the two resonated sections, replace with straight sections. As previously stated this only introduces problems at the gain of convenience; you'll have more flanges, more gaskets that could fail, more bolts/nuts that could rust shut, etc.

Also, that H pipe comes together, so isn't it not a true dual (splitting hairs here) because you don't have individual pipes for each bank of cylinders?

I feel like I'm just trolling now so I'm just gonna wait for short tail catback updates.

I like your ideas a lot but from a production standpoint that will be way too much, we then would have to make straight pipes for both 12" and 18" sections, this then would mean you would have 2 extra flanges on EACH side that really isn't necessary but only to be able to swap out your resonators.

Our H-pipe has 2 outlets, and that 1 short connector towards the end. That's suppose to help cancel out and resonate some exhaust frequencies.

Just to make it super clear, here is the pic again

this top side is where it will connect to your stock cat/hfc/tp/etc

this bottom side is where we will begin to make the midpipe to connect to your short tails/oem rear section

here is a picture of motordynes xyz pipe with the straight pipe option
http://conceptautomotive.net/images/...h_straight.jpg
as you can see it goes from 2 pipes into 1, and exits out of 1. This is not considered a true dual here

the h-pipe and motordynes xyz pipe is the exact same replacement. There's goes from 2 inlets to 1 outlet, ours goes from 2 inlets to 2 outlets.


the midpipe has not been built yet!!
sorry I feel like I'm confusing a lot of people here

I may have interest in h-pipe with 18" resonator mid pipe to connect to my oem nismo muffler.
