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

[Sales@AAMComp]

baseline is with AAM Competition S-Line Short Tails only
second dyno is with AAM Competition S-Line Midpipe in addition to the Short Tails

Hey guys,

This thread has been inspired by edubs and a lot of others who have asked if we've made a mid section from the cat to connect to the short tails (which would ultimately bolt to the stock muffler as well)

I'm simply a mediator and this product will be inspired and designed by you guys! the 370z community!

We currently already make 2.5" H-pipes for our true dual, we will piggyback off this and design the midpipe to connect the H-pipe to the rear section. Our shop 370z goes on the lift today 8/17 for measurements of the midpipe!

The goal:

• 2.5" H Pipe and 2.5" Resonator mid pipes to bolt onto short tails or stock rear section
• This set up mating to short tails WILL be loud
• This set up mating to stock rear section should be close to stock

The purpose:

• Upgraded Y and Mid section 2.5" vs the stock 2.25"
• For those who have Short Tails and want to complete the catback
• For those who want to upgrade their cat back but want to keep sound to the minimal with their stock muffler

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!




straight out

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