Holy- I did notice a little difference after the mods, mainly in response. But it is enough to edge a 12.929 @ 108 in the quarter. So hopefully you can see the difference.

But hey for an easy $500 you can get +~20whp. So it's definately a nice bump for what you pay. Only thing I noticed was a lost a measly 1ftlb of tq with the short tails, which is NOT enough to notice.

I'm just glad I had the time and a shop to do this so people can kinda see how the short tails and the drop ins/post maf fair up with our cars. I'm installing some bumper intake ducts soon. And I no longer have the short tails, so hoping for a little more next time I go to the dyno.

I didn't even think about that. Silly me!

With the FI exhaust and tune you should be above 300. That's you won't regret that exhaust. It sounds really good in person too. Good luck and let us know how it goes for you.

Elan- I hope you break 300. That would be nice, you planning to get a tune with that? Or wait a little longer?

I did three pulls on the same day, first was baseline, second was the addition of short tails, and third was the addition of the dropins and mishimoto post maf hoses... Hopefully this will clear any confusion on these. All results are UNTUNED. I did NOT have the car tuned these are strictly for test results of the additions. Hope you enjoy!

Any questions please ask away

Edit- This was done on a dynojet

Congrats on your numbers

Thanks for taking the time to post this info as this will always help others!

One question I do have.. What are short tails?

Tempestz · 11-15-2013, 12:15 AM

Short tails are the "muffler delete" pipes made by AAM. Other wise known as AAM short tails. They are an axle back exhaust that bolts up to the OEM midpipe and allows you to drop the muffler form the OEM exhaust. They sound great. And are very affordable. They are quite popular on this car.

Hope this helps

Once I get some MAF filters on, I may consider a tune!

Just installed a new axleback exhaust, and some bumper intake ducts to directly route the air to my air boxes.

So far it feels a lot better in the lower midrange and up top. It is a butt dyno, but my butt dyin hasn't failed me yet... I'd like to get ahold of some Z1 headers then in for a tune! Maybe get some testpipes/hiflowcats. But not sure yet. I'll keep you updated to see if the new additions actually helped

These results (~9hp from drop ins) is right in line with my own experience.

Good to see everyone is having good results with them!

Tempestz · 11-18-2013, 04:55 PM

Thanks guys, just trying to show everyone drop ins can make a difference. The 370z has some pretty well designed intakes from the factory.
