However, I disagree that Budget make crappy products - bought a Y-pipe and a B-pipe about 6 months ago(for another Max) and can't be more than happy with the quality. The only problem is that the Y-pipe had the flex section lined improperly and I get bees-in-the can noise sometimes, which is easily remedied with some header wrap.

Just called WSP and confirmed that w/a previous Y-Pipe purchase, the Resonated B-pipe would be about $165 shipped. Forgot the name of the lady I spoke to.
I am waiting on a callback from Dallas to find out if I can make the 2.5" fit w/my stock muffler, since the 2.25" is designed for stock and 2.5" for aftermarket.

2.5 exhaust (y-pipe, test pipe, b-pipe, and muffler inlet) will produce more power than 2.25". If boosted, the gains are even more. I may just get it from warpspeed...i didnt buy my y-pipe from them recently buy my friend did so i'll just use him
#49
Dallas called me back and confirmed that 2.5" B-pipe will align correctly w/the stock muffler on 5th gens. They're going to make my pipe, test-fit it in a 2003, and then ship it to me this week

I was just scanning this thread and saw something that I don't believe is true. You are right about 2.5" inside diameter being right for the catback tubing, but I'll tell you from six years of y-pipes manufacturing that its too big for the rear end of a y-pipe. You want that diameter to open up as it goes back, and 2.5" at the end of a y-pipe will not make maximum power in a normally aspirated car (we get superior results with a <2.5" diameter y-pipe on most s/c'd cars too, but with real seriously modded engines I'd also agree that you'd want to open everything up a bit more).
Not meaning to start an argument, or dis anybody's knowledge, I simply know that this is true based on a lot of development experience.

Not meaning to start an argument, or dis anybody's knowledge, I just happen to know that this is true based on an enormous amount of experience.

I'm sure he didn't mean a 2.5" Ypipe. The y needs to stay the stock diameter to maintain the velocity of the gases flowing through it. If it slows down, thats when you get problems... am I correct?

You're absolutely right about maintaining gas velocity, but the stock y-pipe outlet diameter is too small.

BTW, at what point is full 2.5" exhaust or greater needed on a S/C car? just wondering if i should stay with my setup....

I really find it hard to believe cause i thought the car always need more breathing room but i didnt do the research and I certainly dont know more about y-pipes than cattman so i'll roll with the flow and bow down to the new knowledge i have received .

Heck, "misinformation" would be way too strong a word - some opinions are just more accurate than others. ;-) Its not illogical to make that assumption, it just doesn't prove out in application. Some of the other producers of performance y-pipe seem to think its true as well - seemed so obvious that apparently they never did their homework, or at least they assume their customers won't.
My statement about s/c'd engines and exhaust diameter was meant to be very conditional. We see no advantage in putting a larger diameter y-pipe on a VQ30DE engine with a basic s/c setup (yes, THAT brand), but that would only hold true to a point. Larger s/c pullies, cams, etc. adding up to big power mean more exhaust needing to get out more quickly, so at some point it absolutely would make sense to go to a 2.5" (or even, ultimately a 2.75" y-pipe, though that tubing diameter is difficult to find and expensive), coupled with a 2.75" - 3" custom catback exhaust (custom, since no one makes a production version, and it gets pretty tricky to do w/o rattles because you start running out of clearance room for that size of tubing).
Whatever diameter(s) we're trying to match to engine size, the key aspect is that it gets bigger as it goes back to maintain exhaust velocity and avoid stagnation. Its little known, but Nissan's stock exhaust actually gets bigger (almost continuously rather than in steps) between the cat and the muffler. Its a little too small, but they've got the right idea and that's why aftermarket exhausts don't add a whole lot of power to the VQ30DE engines. [But since Nissan didn't change the exhaust in 2002, its significantly more undersized relative to the VQ35DE engine, and an aftermarket exhaust adds a lot more power to that engine.]
No need to step further on someone else's thread, but I'll note that we're kicking off the big Cattman y-pipe sale at some point in the next couple of days on this group deal forum, so keep an eye out. We usually say, "never the cheapest, but always the best", but at our sale prices, they will be less expensive than some (and still the best).

^^^^ very good information, thanks Cattman. Any chance you guys will be getting a group deal on your catback? or just b-pipe? Interested to see the company's your new prices will be competing with
BTW, so even with boost, although 2.5" or higher is needed when running like 10 psi, do u recommend going like 2.5" or 2.75" y-pipe than 3" catback vs having everything the same size? just as long as back is bigger?

I'd like to do a group deal on our exhausts (b-pipe, muffler or the whole catback), but we pay so darned much for their LA-based production that there's no room to get crazy with price cuts. We have a little more room with our y-pipes and headers, but never the margin that companies like Stillen have (their cost for a y-pipe is about 30-40% of ours!). Its partly a matter of volume, but we also insist that they use the best materials and subcomponents, and expensive production methods such as using TIG welding and the really expensive hand-made 2-1 merge collectors featured in our y-pipes (one of our biggest power advantages over the competition, none of whom do it this way). Its not just hype, these costs add up dramatically. Call it an ego thing, or a foolish business practice, but I've always been determined to make the best parts, knowing that I'll never make the most money that way.
At some point we may be forced to look at off-shore production, but I do all I can to keep it in the US (our headers come from New Zealand, but that sure doesn't save us any money), both for patriotic reasons and the convenience of shorter supply lines and close relationships with my fabricators (in almost all cases, my suppliers have become friends over time, so there are personal loyalty issues "getting in the way of profits" as well).
Let's say you're starting out with an engine that only has a supercharger added - everything else is stock. Pretending that you had all possible sizes (inside tubing diameters) of y-pipes and exhausts available for experimentation, you'd find that increasing the size from stock would give you more power up to some point. In a normally aspirated engine, going beyond that optimal setup would lead to loss of power in the lower end. In a forced air situation, it would be more a matter of the gains just stopping, rather than the power falling off.
That said, the optimal design involves increasing tubing diameter as the exhaust goes back, but there's no point in going too big if only due to cost factors - the minute you go beyond 2.5" you're paying big time for quality custom work (and accepting that custom work is a "on-off" process without the development and testing that should go into a production piece). Other practical matters include the limitations of available materials (not easy to find 2.75" ID 304 stainless tubing and you pay through the nose for it).
We've actually made "big mouth" s/c y-pipes in the past, but the demand was never there to support the production numbers we needed to run (I still have a 3" s/c y-pipe for a 99-01 CA/NLEV car that I'd love to get rid of).
Given your interests, don't forget about headers. If you're serious about making normally aspirated or forced air power, the only way to capture all the power available from exhaust modifications is to start out with a header. If you want the one that works best, look at ours, which includes a y-pipe that is integral to the design (you cannot make a good set of headers using a performance y-pipe that attaches to the stock manifolds). Check out www.ceasarschariot.com next week, they'll be doing a thorough review of the Cattman Performance Header System.

I'm just planning on getting a y-pipe and keeping everything else stock. I'll probably put on a 5th gen muffler later on when this one craps out.

MrRoger ... you will see performance gains by replacing your stock Y & B pipes while keeping your stock muffler. Unfortunately, since we can't search I cannot find the posts with dyno sheets .. but it's been proven.
Not sure how much more power you'd get with an afermarket rear section, probably not much.
Really, your best bang for your buck is the Y pipe (at least on the 4th gen).

All of our y-pipe versions - including our 02/03 y-pipe (part #YG5A) - have been on sale for the last couple of weeks on the group deal forum. Tomorrow's the last day, price is marked down from $350 (they haven't been priced at $400 for years) to $285. Just call 800.759.9920 between 8-5MST.

Sweet a 2.5" bpipe will align correctly with a stock 5th gen muffler!
This will be the route I'm going in a month or so.

Actually, I really would recommend against that. Save up for a pipe from another company. If you follow my link in post #63, you'll see why I say that...
#75
That's not too bad. If it's the same b-pipe used in their catback exhaust systems, it looks pretty nice. SS and looks similar to the Cattman pipe. If we could get it under $200 shipped, it would be the same price as Budget too.
Do they make it in a 2.5" resonated size? As soon as I get my refund after I return this Warpspeed piece of crap, I'll be buying a real B-Pipe
