Does anyone have the Warpseed Y-Pipe on 2k2 or 2k3. I search but didnt find anything.... If so what was the gains?

 

Here's a post I made some time back reviewing my WarpSpeed Y and B pipes:

Subject: WarpSpeed 2K2 Y & B pipe installed and dynoed w/pics

A couple months back I sent WarpSpeed Performance an email expressing my willingness to volunteer as WarpSpeed's "Test Monkey" for their new 2002 Maxima Y & B pipes. I was then contacted by Dallas, owner of WarpSpeed. He indicated that a prototype was being built and asked if I would be the first to test and evaluate the pipes for him on my 2K2 Maxima. I readily agreed. After they were pre-installed on a rental car at his shop, they were removed and sent to me.

The pipes came in a large box, well packaged and protected. The quality of packaging became evidence of the quality of product to come. All welds were top notch and all bends nice and smoothly mandrel bent.

WarpSpeed will offer 2 1/4" and 2 1/2"B pipes with and without resonator. I elected for the 2 1/2" B pipe without resonator.

I took pics before the install, did a little weighing and visually inspecting all parts. All tubing in my kit was aluminumized steel. I understand there will be stainless steel in the offering for production units. Had I the opportunity I would probably have opted for the stainless but this aluminized tubing should last pretty well. The entire system weighed 3 pounds less than my factory exhaust however my factory exhaust does have a resonator. Here's a pic of the complete assembly before installation: http://www.mustangmods.com/publish/8...rpSpeedY&B.JPG

I wanted to be able to report first hand to Dallas my findings regarding easy of installation and any other problems I might incur so I decided I would do the install myself. I did have a little tweaking to do as with any prototype product in development. With Dallas's help we worked through my concerns. All production units will have the necessary revisions so these babies should bolt right up.

At the same time I installed these pipes I also removed the small pipe leading to the muffler and added a 2 1/2" pipe as shown here. I ground out the portion leading into the muffler entrance to remove the tubing ring left after sawing. The muffler is now 2.06 ID verses a small 1.77 with the original factory pipe. The 2 1/2" tubing fit over the OD of the remaining muffler hub nicely. See pic.

I would highly recommend this mod or an aftermarket catback to fully maximize flow capability of the Y & B pipes. Should you go with an aftermarket muffler you might want the resonator pipe if you want to keep that noise level under control. With this factory muffler and without a resonator, a slight rumble is all you can hear. My system is quiet. Probably less rumble than many vehicle factory exhausts.

No SES light beaming my way, no bees in the can sound. Idle quality is perfect! No engine vibrations or noises other than a slight exhaust rumble as previously noted.

Here is my engine dyno results before and after WarpSpeed's pipes:

Dyno 002 is my bone stock engine with factory air filter in place. 003 is with the factory air filter assembly removed from the factory box. The box now has a large opening from the top much resembling flow equal to any of the aftermarket intakes.

Dyno 005 is ran with my stock air box and with the factory filter in place but with WarpSpeed's Y & B pipes and my modified muffler/pipe. Dyno 006 is with the factory air filter removed once again.

I gain 20.9 hp and 23.6 lbs torque! Not too bad and still quite as a mouse with my factory muffler, factory cats and completely street legal!

 

I was told a couple weeks ago that the TIG welded y-pipes will be out in a month or two, but they've got the MIG welded y-pipe in stock right now. Added with their B-pipe, the gains should be 20+whp as Larry stated. I opted for the MIG welded y-pipe because I'm impatient like that.. we'll see how well it works out in a few days

 

Just what I needed. Thanks

 

so is the warpspeed Y out yet ?? if so where is it sold? if not when will it be out?
thanks

I can't seem to pull up all the dyno links... are you saying you got the above posted gains with just the Y & B pipes alone or is that the total gain with the "airbox mod" and the muffler pipe change?

Nice Set-up.

 

Here's the link to my stock dyno: http://www.mustangmods.com/publish/8...ockmaxdyno.jpg

The hp gain is with the air filter assembly removed, the Y & B pipes and the modified muffler.

 

What's the difference between TIG welded y-pipe & MIG welded y-pipe?

 

I think TIG welds are supposed to be stronger and more durable. When I was little I remember my Dad had both kinds of welders in the Garage (which was actually an 80x100 or so shop) and I thought that was one of the differences.

 

i believe it's that TIG welded pipes weld to themselves while MIG welded pipes use a different type of welding material, and by that making the TIG welds durable cause they're attached to each other.
actuall difference, i personally don't see any. i'm just as happy with MIG that i don't feel it's worth poppin extra for the TIG. unless someone else here would like to shed like on the subject.

 

TIG welding vs. MIG welding

that should answer your question

 

The difference then between dyno 3 and dyno 6 is 13whp and 17wtq, so is that what can be reasonably expected from the Y and B pipes from Warpspeed? I'm just trying to get an idea on what the realistic gains are as opposed to what the manufacturer's claimed gains are. I've searched and can't find a link to a dyno test done comparing a non-modded with a Y and B only modded car.

 

OK!! I'm sold!!

 

Are the 2002-2003 Warpspeed Y-Pipes emissions friendly?
Whats the difference between a Cali-Spec and Fed-Spec Y-Pipe?
Is the 2002-2003 Warpspeed Y-Pipe a factory OEM fit?(Will there be any custom modifications to make this fit properly etc.?)

Any fellow members wanna shed some light on this? Want to know before I purchase one.

Anyone?????.......

 

ok it looks like im ready to go for aluminalized y, living in california, i dont need to worry about rust.
anyhow, I saw the dynos and I was wondering If I throw a B pipe on as well, how much more power will i gain if I keep thje stock muffler. Is it worth spending the extra dough?

thanks

 

Are both of these pipes bolt-ons? What's the Y pipe whp and torque gains and then with the B pipe? Why isn't everyone jumping on this?

 

I'm going to be jumping on this as soon as I can save up the $$$.
I already have the 2.5" high-flo cat-con. Will be purchasing a B-pipe (with resonator) and Magnaflow muffler to go with it.

I was looking under my 2k2 the other day, and the B-pipe really is tiny. So is the pipe leading into the muffler. The Magnaflow mufflers have a 2.25" inlet. I have a feeling there is a few extra horses to be gained by ditching the factory muffler b/c of the small intlet diamter and the overall restrictive properties of 99% of all factory mufflers.

Another observation. I can feel a dip in power dramatically at over 6300 RPM or so. Its like someone turned on the A/C. I have an Injen Intake, and I have a theory that exhuast gas volume exceeds the factory system's ability to expel all of it during every stroke. I fully expect a 20hp/20tq gain when I bolt on the new exhuast. I don't live anywhere close to a dyno so I won't be able to confirm this but I will be able to tell if the tires break loose easier.

In summary, you're going to gain alot more horsepower from the combination of an intake and full exhuast than just one over the other, as was proven in Larry's dyno results.

Supposed to be bolt on for 2k2-2k3. I'm waiting because Warpspeed has yet to produce an honest dyno showing what the gains are with just the Y-pipe and then with the added B-pipe. Their website claims "20hp gain with our b-pipe" or something to that effect but the only dyno coming close to that posted here is with the Y and B pipes, an open airbox, and a fatter section of pipe running from the B to the muffler. From the tests I've seen the gains from the Y and B are about 8 to 13hp and 11 to 19tq (iirc).
I'll be waiting to see what the Frankencar company comes up with this summer before deciding on which exhaust to get.

I feel with the recommended revisions I made for Dallas that these pipes will be a bolt on project. I suppose the worst problem is B pipe interference with the cross brace. That's the brace that goes under the B pipe just aft the rear cat. I dropped my brace with spacers and longer bolts. Maybe it could just be removed. I really don't see it doing much but Nissan must have thought it was needed. The larger pipe and without the crush makes a very close fit. I was willing to working around this problem for the added hp the larger flowing pipe gives. You must have pretty good clearance too because engine torque while accelerating will cause it to rub and make noise. Polyurethane motor mounts would be a great help in reducing engine movement to help eliminate this problem.

I'll quote my original statement, "I did have a little tweaking to do as with any prototype product in development. With Dallas's help we worked through my concerns. All production units will have the necessary revisions so these babies should bolt right up."

As far as hp from the Y pipe by itself, I don't think much. I drove my car with only the Y pipe and felt no gains by the "butt" meter. When I then added the B pipe my car came alive with noticeable butt meter gains. As the saying goes, you are only as good as the weakest link. I don't think the B pipe alone would give much gain either but I did not try that. Also if you don't do something about the small pipe going into the muffler I don't think you are going to see much gain.

It would be interesting for me to remove the factory muffler altogether and see if I gained even more on the dyno. That was cost preventative at the time and I did not give that a try. I do feel there is more hp available here though as 02MaximizedVQ mentioned, most factory mufflers are pretty restrictive.

Another note of mention is the two precats. They need porting to fully optimize the flow potential of the two pipes. The front precat has a cast dimple on the discharge end which is readily noticeable when the Y pipe is off. You can see it's curvature on the outside too. The 02 sensor is also right at this point which farther restricts flow. The casting appears to be fairly thick so a fair amount of porting is possible. The rear precat is 1 5/8" inside diameter which can be opened to about 1 3/4".
