Basic Exhaust Question

I'm not sure if I understand the parts of the 4th gen exhaust. I think there is the "Y" pipe, the catalytic converter, but then I dont know if there is another pipe running from the catalytic to the resonator or if the resonator and the pipe are one piece, then I believe there is what is called the "B" pipe followed by the muffler. I'm trying to get this right so I can shop to replace my rusty exhaust.

i looked at the bottom of my car and and it shows the B-pope bolted on right after the resonator and those 2 are separate pieces. but i can't tell if the catalytic conv is one piece with the resonator. i'd check with http://www.stillen.com/sportscars_products.asp?make_id=23&model_id=284&StartYear=2000&EndYear=2001&cat=2&subcat=162&Brand=

Ok, from what I understand, it goes...Manifolds, Ypipe,Cat, Bpipe(I'm pretty sure the resonator is part of the B), then the muffler and tip. I'm pretty sure thats how it goes.

Oh yeah, check out www.budgetexhaust.com They list all the parts

VQmax95 is right. That's is exactly how it goes. The resonator is part of the B-pipe.

So then your Maxima has the manifold (which obviously cannot be seen from under the car), then comes the Y-pipe which has two catalytic converters (if you have the stock one), then comes the main catalytic converter (yes ANOTHER cat, not a resonator), THEN comes what is known as the B-pipe which includes the resonator (again, IF it is the stock one) and finally the muffler and tip.

I agree with Max_PR thats exactly how I saw It come out of my 98se

i think the b pipe is 2 pipes, one is the resonator which is almost totally straight and the other is the part that forms the "b" shape.

these are the same stillen b pipe/s that were on my 4th gen

http://store4.yimg.com/I/southwestautoworks2002-store_1766_18305683 no resonator on these

At first I couldn't find the section with the Maxima parts, but then I clicked on the BudgetPerformance logo (main page), then on the Budget Performance page you click on Custom parts in the flaming menu bar and "bingo" you can look at a list of applications and look at pictures of some parts. They have the resonator and the "B" pipe all as one part.

Thanks for the help.

Here is a pic of the Budget B alongside the Stock B pipe. This is the non resonated Pipe from budget. The resonated pipe would look similar to the stock one.

BP, why are there 2 pipes in that pic? I'm pretty sure all that pipe wouldn't fit under the car. Of course, I could be wrong, but I'm pretty sure the B is just one pipe.

there were B-pipes for sell on eBay once. it was a separate piece from the resonator. but i donno how much more it would help performance since it makes up such a small section of the exhaust. or does it?

The B-pipe is generally dellivered in two parts for delivery convenience. But it is sold as THE B-pipe (as one item).

As you saw in the previous picture de Budget B-pipe comes as a single part, but the Stillen B-pipe and Warpspeed Performance B-pipe (the one I bought) come in two pieces to be put together during installation.

The stock B-pipe is a one-piece Item.

you put them together end-to-end so they make a lower case "b" shape

Yeah, I realize that now. I was talking before i thought...that gets me in trouble sometimes.

I have two questions about the pipe in the picture below.

What does it do to the exhaust sound if you use the B pipe without a resonator?

and

What kind of material is that budget pipe made of? It looks pretty shiny in the picture below.

The budget pipe is T-304 Stainless steel. I've heard that without a resonator the exhaust has a loud raspy sound. I've also heard that its pretty "ricey" sounding. I'm not really sure because I've got stock exhaust.

How silly of me. I should have remembered that I too have been on the Budget webpage and seen that the pipes are made of 304 stainless. I see that you can get a stainless "B" pipe with a resonator too. That's the route I will take. Thanks for your help everyone.
