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

[JC671]

Khoi, can we get an ETA on the mid pipe? Also has the short tails been dyno tested? Is there an increase in whp other than just sound? How much WHP was gained with everything else stock and just the short tails?

Also, check PM

I was under the impression that the short tails have no factory supported dyno charts/power loss/gain, i.e. that AAM did not specifically dyno their 370Z to find numbers.

If anything I would suppose that there would be some mild horsepower gain and mild torque loss, but not anything more or less than 2 each.

I went for an xpipe instead and i am very happy with the results. The car is significantly quicker in all gears.

lumpy looking pipes and horrible welds in that pic.... best of luck with it.

i remember a thread about a company going back and forth with X/H pipe configurations and found the X to make the most rasp. when i have time ill search for it.

Thanks for the comment Fuct. I only paid 120 for this and its not done yet. I have 2.5 inch flex pipes on order. Xpipe will sound the best when I upgrade to Meisterschaft Axel back.
