I did some searching on this topic and I could not find anything. I know there has been a discussion of the 2k2 Maxima's hp vs the 2k2 Altima's hp, but what about the 2k vs the AE. How did Nissan free up 5 more ponies? Has anyone driven both cars?

*** I think I remember a post on this in the past. Given the deign of the intake and exhaust, freeing up 5 ponies should be cake. Hell, guys are freeing up 9 horses by cutting up the OEM intake.

I had a 2001 AE. The 2001 AE had 5 extra HP than the regular 2001 Maxima. This was accomplished by using the exhaust system used in it's Infiniti cousin.

Not sure, but I think it was with a valve in the muffler. Like the 3 liter Infinti, which I think always had the 227 hp version.

As far as comparisons go, I don't think you'd ever feel the difference, though you might be able to see it at the top end in a side by side comparison from a 30 mph roll in 3rd gear. I say "might", because 5 hp is at best only a little more than the hp variation due to normal production variances. IOW, a strong 222 hp version could very well run even with or even very slightly out-pull a weak 227 in such a test. Mostly, the extra 5 ponies was for bragging rights, to make the AE the performance "top dog" for marketing reasons.

I raced an AE with my 01 SE. I had just intake and beat him by about 2 car lengths up to 90 mph. I'm not sure about the 5 hp difference but i know my intake couldn't have made to much of a difference. We were also both auto's. After it the driver of the AE asked me to roll down my window, he asked what i got and than was interested in where to get aftermarket parts for his maxima. Hope this is some good info about that extra hp they put in the AE.

If you compare the exhaust tips, you will notice that 2K has straight and AE has slightly downward bent ones, just like on Infinity I30. This creates increased backpressure and voi-la 5 more HP. Someone correct me if I'm wrong.

That's pretty much what I thought too. The gases will exhaust easier in a straight horizontal pipe, hence lower back pressure. IMHO the 2k muffler looks much better, though. Has the difference been shown on a dyno?

i was under the impression that back pressure made torque. i could be wrong though. thats why it never made since when a civic just put on a muffler because it took torque away which it didnt really have in the first place.

Does the AE/Infiniti muffler have the same variable valve that the regular 00-03's mufflers have?

People have checked parts for the AE Vs regular's.

Everything is the same except the mid-pipe. Somewhere after the Y-pipe but before the muffler, Nissan installed a freer flowing setup. There is nothing different in the mufflers, both has dual tips; one is shaped differently, both have flaps, both will perform the same.

AE's put down similar power to the regulars though. It could be that the VLSD adds to drivetrain loss. No advantage except powering out of corners in automatics. Automatics aren't tire burners from the factory reguardless of trim so really there is no advantage in stand-start acceleration in dry weather. In manual cars, you'll get the power out of corners and better traction. When you modify and add power, VLSD comes in handy for extra traction.

The VLSD was only available on Canadian Maximas right?

No 'merica got it too.
I also heard the difference was in the midpipe being less restrictive giving the "claimed" 5hp boost.Anyone have dynos for stock AE VS Stock SE(2001's)?
