Still no update?

We just received a stock nismo h-pipe and midpipe thanks to a forum member, dmhenderson

We should be making some solid progress from here. I just did a rough measurement of the stocker and I was a bit surprised at how small the stock exhaust is!

the inlet of the stock nismo H pipe is about 2 1/4" and the outlet where it meets the midpipe is about 2 1/8", same with the inlet of the midpipe, after the resonators the piping gets slightly larger again to 2 1/4" so the outlet of the midpipe meeting the rear section is about 2 1/4"

Not sure why the piping changes sizes but I can definitely see Nismo guys upgrading their h-pipe/midpipe to a full 2.5" dumping out to their stock rear section for some good increase in sound and performance

stay tuned..

So ready. Do you think there would be enough room for some resonators Khoi?

without a doubt there will be resonators on the midpipe portion, similar to your stock midpipe!

keep this reasonably priced and you have my money ASAP. none of that 1000 dollar AMUSE BS!!!

Hey chops are you going to the BAZ meet on the 16th?

very VERY small teaser for you guys :)

I'll take it now!
How would it sound with the stock nismo exhaust if you just change the H-pipe?

I thought you guys were just doing the H-pipe. Didn't know you would be doing the mid pipe as well. But if so are you gonna make it a package deal or allow us to buy the piece we want or need vrs the two piece kit? Thanks and I hope it's done early 2013..
CHEERS!!

oh trust me, you will WANT to upgrade both pieces.. the H pipe about as thick as my sharpie aka very very small diamter, and it mates into the midpipe which is about the same diameter

read a few post up when I measured both of them. Instead of these awkward diameters, it will be a straight 2.5" from the H-pipe, to midpipe, then you can mate it up to the stock rear section! This will unlock some power for sure!

It's kind of hard to tell but you can see the pipe before the resonator (towards the bottom of the pic) is slightly smaller than the piping after the resonator, it's an awkward bottlenecking system.

When all said and done we will test the h-pipe/midpipe combo on a stock base/sport rear muffler since we don't have a stock nismo muffler to test it on. It SHOULD sound similar but we'll see how it sounds! We'll also be testing it out with our short tails!

rear section is done and here are some pics of it tacked up. The h-pipe portion should be easy, hoping to have this all up and running very shortly here guys!!

Smallest set back would be clearance, which shouldn't be any worst than any true dual systems that do not criss cross in the rear. A few reasons why we did it the way we did, 1) least amount of bends, better flow 2) less bends = less welds, less chances of cracking, less labor, less cost!! As you can see the midpipe is almost at the same angle as the rear muffler, shooting straight up, no turbulence there

here you can see the difference in piping size! Our system vs the stock!

That looks nice!

Payment at the ready

Patiently waiting on the Hpipe for my Nismo. I want to get rid of my okay crafted xpipe. lol

Johncy, I will double check if we will be selling it separately like that, After looking at how small the factory H-pipe and midpipe is, I highly suggest upgrading both pieces

How much are we talking Khoi? Xmas is right around the corner! Any specials?

ill stop by!

No clue on pricing yet, I don't see this going into production anytime before xmas. I will try to do an introductory price for you guys though

yesterday the H-pipe portion was tack welded up, except the horizontal cross piece. This piece should finish on Monday

Hopefully we can test this out with the stock rear section and short tails very shortly after.

After the initial test, the jigs will be made so they can go into product.

AND THEN there will be an official release with all the information and pricing

rear section wedled up, h-pipe needs the cross piece and should be done here in no time!

Looks good!

Can't wait for a sound clip with stock exhaust an then your shortie's so looking forward to it.

if aam offered a full CBE(like this with the short tail exhaust) i would buy it, i love the way the short tails sound so more of that noise will just be sex to my ears

Yup! And that's why we are calling it the S-Line Midpipe, to go along with the S-Line Short tails

Short Tails will be sold separately, so will the midpipe, we will package the 2 together for a "package" discount for those who just want to run straight pipes!

Totally interested!! Would love to see the Mid/H pipes on my NISMO with OEM muffler section and LTHs!

You might be the first to do this! But we will be producing sound clips with this set up on stock rear muffler, on stock header/cats though

but you'll get the gist of it!

testing our first prototype piece today on a stock 370z. Customer already had our short tails!

sound clips with the short tails to come, we will not be doing a dyno/sound testing with the stock rear section so we will be offering a discounted rate for a 370z that wants to test this midpipe combo on their stock rear section in exchange for a review and sound clip!

we redid the intermediate section to have better clearance with the sway bar, pics of the completed H-pipe here!

Simply beautiful. Great job! Still in BTW.....

370z with AAM Competition S-Line Short Tails 281 whp 233 ft lbs of torque
370z with AAM Competition S-Line Midpipe + S-Line Short Tails 301 whp 252 ft lbs of torque
+20whp +19 ft lbs of torque

gains would be higher if we compared from stock to this combination!!

dyno chart coming shortly!

Damn those are some awesome gains!

No other mods on the test car, correct?

Did you tune it as well or just add the mid pipe?

whoa, I disappear for a bit and these are done! awesome.

No one has volunteered to run only straight pipe? I have unres. test pipes and the short tails. I can't even imagine the noise.

nothing else done to the car, everything was on the stock tune

dyno graph and vids coming shortly! I just road in it and it sounds amazing, highway cruising the db reader was mid 90s, WOT right around 105db

sounds awesome!

damn, that's loud.

Very impressive!

maybe I'm going deaf but it wasn't that loud! haha
