I'm still working with Dallas on this one. The engines in the manuals sit lower than the engines in the automatics. So if you're an auto, you should be mostly ok. But if you're a manual, then the pipe hangs too low and is rubbing against the cross-brace underneath the car. For now, you can get 5 washers per bolt (40 total) and bolts that are 1/2-3/4" longer and use that to lower the cross-brace. Do NOT remove the cross-brace, as it protects the exhaust from damage during an accident. If you remove it and are in a side-impact accident, the exhaust could get pinched and the engine MAY (key word) explode. Just a warning to all who have removed the brace.

I used to think $100-150 per 10HP NA was worth the money. Now It looks like it'll be $200-250. But to spend $200 or more for 5HP that just doesn't make much sense to me, how about you...

why does everyone keep bringing up headers? every time i post about the possibility of headers the idea gets shot down. no one has answered whether or not it will have any benefit because only one person has created headers for our cars.
of course i would love headers for our car, but judging from the responses, we are going to have to make due with just the y-pipe.
the 3.5's need headers like i need a hole in the head. it seems like us 3.0 owners are going to get skipped as far as R&D, and any other aftermarket support.
yeah yeah, go turbo, supercharge- not really an option

For 2002 and on, they WILL NOT benefit more than a few HP. (Well under 10) Nissan redesigned the Y and many of the problems that plagued it have been corrected. Any help will come from the slightly larger diameter in the tubing used to make it. Also all of the people that have dyno'd with an aftermarket Y and posted numbers have replaced the B too. We need larger diameter from the manifold back with the precats removed. Hotshot has a prototype done for the Alty and at 1st look the numbers are up there. $tillen is still working on theirs...

im looking at getting the obx stainless steel headers for the 00 and i didnt know that the y-pipe isnt needed when replacing the headers???? are you sure about this? i was about to order a y-pipe now if thats the case i wont. the y-pipe and headers are the same price

Not true. The reason that aftermarket y's don't make too much power on 2k2's is because they don't eliminate ANY precats. The precats are the bulk of the restriction in our exhaust system. From spending quite a lot of time under the car today, it became apparent that the precats in the 2k2 are located IN the actual manifolds. If you can eliminate both of these with headers, I wouldn't be surprised if you could gain as much or more than the VQ30 with just a y-pipe. Besides, the benifit of headers doesn't come from diameter of piping, but by equalizing the backpressure across your exhaust pulses thus allowing for better breathing.
The altima guy posted a dyno that shows 238hp or so on an AUTO. Fairly impressive if you ask me.

In early 5th gen most Y's remove 1 precat not both and still show a large gain. I have yet seen a Y for an 02+ show a nice gain.
Yes 238hp is impressive, and if Hotshot doesn't end up doing them for us I will have it done custom locally or take a hard look at the $tillen setup.
