Now that I have the y-pipe, I wonder should I also get the b-pipe and cat to complete my exhaust system? I read a post before that stated that there's no real gain from a cat. Maybe I should just get a b-pipe? I heard there's some gain from that. How much does the Stillen b-pipe cost anyway? Thanks. I would like to get a Apex-i WS cat-back exhaust, but I don't like the finish of that exhaust. Any suggestions? I'm also planning to maybe replace my Focuz exhaust with an Apex-i N1 exhaust.

I would get the b-pipe for sure. It is worth some HP. Stillens will be louder because it has no resonator, but I think it will fit better than my Courtsey Nissan pipe did.
I still have a stock GXE muffler so I cany help yoou their... I like it resonably quiet.

I've been told the B-pipe is a waste of $$$ and it doesnt really do too much. This is just what i heard from a couple of people with it. THey also said they didnt notice any great power increase. I've also heard that it made a big diff w/ other people. The only true way is to ask anyone who has done a dyno with it.

Are you planning to get a different type of exhaust? The sound don't really bother me, I kind of like it, it's not really that loud. Unlike some Honda/Acura...just so darn loud, but they weren't going anywhere.
Well, I think I'll get the Stillen b-pipe then. How much do I expect to gain if I get a test pipe? Man, my car is going to be really loud if put both the b-pipe and test pipe in along with the already installed y-pipe.

The guys that are still using the Courtesy provided extension piece with the B-pipe are the one's that aren't seeing any gains. I felt a nice gain in low to mid range grunt. My ets dropped by over .1 and I gained a consistent 1.5mph. This "gain" was seen in the first 1/8th mile which means I'm making more lowend. The B-pipe is worth it, especially with the Y-pipe.

A for a HP guestimate ~5 for the b-pipe and ~5 for the test pipe, but this may be at the expanse of a little low end torque. But dont worry the VQ needs the additional top end power, so IMHO loosing a little low end is worth some more top end.

You're right, the VQ definitely need some more top end power. I noticed my top end most definitely needs improvement. My low end power is pretty good now. However, top end needs work. I noticed this most often when I'm driving fast on the highway, the car just seem not to be pulling much at the high end even though I'm flooring it. Sure, my car does feel a bit stronger now, but I guess I thought my top end would be as strong as my low end power. Well, Stillen b-pipe it is. I'll contact you Matt when I'm ready for the test pipe. Thanks.
I wish I got the money for a supercharger.

B pipe is not a waste of money. It's one of those things that you need to get when creating a more efficient, free flowing exhaust system. I would leave the stock cat alone in a AT maxima, but if you're running NOS..go ahead and knock it out.

It is nearly impossible to gain any true topend with the VQ and that's the sad truth. Making power past 5800rpms will not happen unless you are running a SC. The 4th gen VQ intake manifold is what restricts topend flow. The manifold is a long runner design which increases low and mid range power. Short runners are what is needed to make power past 5800rpms which is what Nissan did with the 5th gen (a varible length long/short intake runner design). The SC actually pushes in a lot more air so it can overcome the runner design to a point. The Y-pipe "fattens" up power all thru out the rev range, but doesn't increase the VQs ability to increase flow past the intake manifolds design.
The B-pipe WILL gain you more lowend. My car was much stronger from idle to 4500 rpms. After that it's very hard to tell. Like I said, I've got the timeslips to prove the gains.

If I punch it, the noise will be louder because of the CAI and y-pipe. When I'm cruising, especially when I start off, going around 1500-2000k rpms., there's this drone that's tend to get annoying. When I step on it, and the rpms rise, it get louder, but not the annoyingly loud sound when it's below 2k rpms. Anyway, I assume by getting a Stillen b-pipe, my exhaust system will get only louder, right? Any suggestions? Maybe get a 2k Maxima SE exhaust? If I get a Stillen b-pipe, won't it be useless/dumb to get an Apex-i WS exhaust because it's a cat-back exhaust?

i know you have the timeslips, but i'm wondering how is it you can tell that your gains in the 1/8 mile are attributed to more lowend torque(besides your butt dyno)?? i based my reasoning on exhaust theory and back pressure. you based it on 1/8 mile runs that really don't tell you whether or not your are gaining high end or low end. i'm not trying to start an argument, i'm just curious as to how this really works. i suppose the only way is to get on a dyno and do a run with stock b-pipe and a run with aftermarket b-pipe.

That's ok Matt. I think I'll get the Apexi WS cat-back. As far as looks, the WS isn't that bad either.
However, I'm wondering since the WS is a cat-back, is the piping of the WS better than the Stillen b-pipe? Similiar gain in performance I would think?

I too am thinking about that B pipe. I do not want anything thats loud. My car is already a tad bit louder with the Y pipe and ShopVac intake and now my 4" non resonated tip. I got some extra cash lying around too, and if it'll make a difference in performance I might as well do it. Unfortunately I have a 97 and it might not bolt up.. but I'll do some more research on this one. I do see the rather restrictive looking crimps on the OE B pipe. While I'm at it, I'll probably sand blast the OE muffler and give it a nice pretty paint job :-)
About the intake manifold, I too thought of the idea but after searching and reading
http://forums.maxima.org/showthread....5&pagenumber=2
it just isnt worth the potential headache and cost. Unless somebody actually performs the mod and says "this is how its done in step A B C..." etc....
