Also, check PM

4whp increase i believe. That was without a tune.. i think we lose -1 tq or something like that

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.
