First and foremost, thanks to everyone who have been extremely patient with me on this project, I know it's been a long 5+ months, but here it is!

One of the bigger restricting components on the 370z is the exhaust system. Nissan figured this out when they redesigned the catback system for their Nismo 370z to adapt a more free flowing system which included, a redesigned H-pipe with dual outlets vs their Y-pipe with a single outlet, and a more free flowing muffler. With the revised exhaust system and a slight tweak to the ECU, Nismo 370zs gained 18 crank hp from the factory

With the success of the Nismo exhaust, AAM Competition took this one step further and designed the S-Line Midpipe, a true 2.5” exhaust system connecting the factory catalytic converters to the stock rear muffler. The factory Nismo H-pipe and intermediate pipe starts off at 2 1/8” from the factory catalytic converters, opens up to 2 1/4” at the intermediate pipe, then taper back down to 2 1/8” by the time it hits the muffler. Although we would never doubt Nismo parts, we took on the challenge of designing a larger and more efficient system. The S-Line midpipe has been dyno proven to gain +22 hp to the wheels and +20 ft lbs of torque over a stock 370z, equipped only with our short tails, all else stock!

AAM Competition S-Line Midpipe is handcrafted with mandrel bent 2.5” 16 gauge T-304 stainless steel. The system consists of a 2.5” H-Pipe and a 2.5” resonated intermediate pipe. This makes it perfect for those who want the added performance of an upgraded midpipe but want to keep the factory muffler to keep exhaust volume down, or those who already have our short tails and would like to continue the rest of their exhaust system.

Features:

• 2 component system; 2.5” H-Pipe and 2.5” resonated intermediate pipe
• Connects factory catalytic converter to stock rear muffler (Nismo or Non Nismo) or;
• Direct bolt on to AAM Competition S-Line Short Tails
• 2.5” mandrel bent 16 gauge T-304 stainless steel
• T-304 stainless steel flanges
• Precision TIG welded in house
• Dyno proven +22 wheel hp +20 ft lbs of torque in conjunction with S-Line Short Tails
• Dyno proven +12 wheel hp +7 ft lbs of torque in conjunction with stock rear muffler
• All hardware included
• Made in USA

In response to a member wondering if the piece can be sold separately:

When we designed the H-pipe, we did make it interchangeable to fit the Nismo intermediate pipe, will not fit base 370z intermediate pipe considering that's a single inlet piece; however from a production standpoint they do not want to split it up.

Gain wise, I would have to do a lot more testing if I were to only sell the H-pipe separately. Believe it or not, you do not want to upgrade the H-pipe only, as the oem system both Nismo and non Nismo is extremely restrictive (diameter wise)

$900... Wow.

Me want...how do i order? Special discount with the short tails?

balls... 900 dollars? it's pretty much equal price to the current catback then.

actually it would be a bit more than the catback...

There has been talk about discontinuing our current true dual, this way we can design a "criss cross" style axle back to mate up with this midpipe. That axle back can then also be sold just as an axle back, or combined with this as a complete true dual. I attached a quick render our engineer drew up

Nothing set in stone yet

As of right now the MSRP is $899 with sale pricing being at $849. If there is enough interest, say 8+ sets I can most likely bring it down another $50

i'd honestly buy this if it was just the H-pipe (no plans to really swap out the mid-pipe yet), and at a reasonable cost :)

ive had money put aside for an H-pipe (from fast intentions) for the longest time!

How much with the titanium tip short tail? (Nismo fitment)

Mind me asking why a "H" and not a "X"? This H with the shorties have better gains than any cat back on the market isnt it?

Does the price include gaskets + new hardware; e.g. bolts, etc.? How much shipped to 92604?

So what is the price discount price combined together with the titanium short tails?

This price range looks to be about higher than the F.I CBE..

When is shipment gonna be available and is there any wait time?

Working with the boss man to see if he's willing to split up the product to full midpipe to H-pipe only. I'll get back to you guys shortly on that. When we built the H-pipe it was mocked up to fit stock location, but we are going to test fit the H-pipe on ONLY, to double check

The product does come with all gaskets, bolts/nuts/gaskets

Why we kept it as an H-pipe and not X-pipe? Again we sought after the Nismo design and just bumped the piping diameter

Combined with short tails I can knock off $150, on any variation of the short tails.

As far as inventory, I should have about 5-8 sets of short tails coming off the line by the end of tomorrow. I have 2 complete sets of the midpipe at the moment, and should have a total of 5 by the end of Friday

what is the piping diameter of the nismo exhaust?
