MIDPIPES!!! They're here!!!
Sorry about the long wait, but they finally came in. We now have the following intakes:
Maxima
2000-01 (pictured)
2002-03
Altima
2002 3.5
2002 2.5
The sale price for the Maxima midpipes are as follows:
2000-01
$55 Midpipe kit only
$109 Full intake kit with K&N filter
$159 Full intake kit with Apexi filter and adaptor kit
2002-03
$49 Midpipe kit only
$105 Full intake kit with K&N filter
$155 Full intake kit with Apexi filter and adaptor kit
Shipping is $10 for any of the above kits.
I'll post some more pics on the website as well as an order page by this Sunday. In the mean time just send me Paypal payments to: sales@berktuning.com

Cars pulls harder too. It also makes this air sucking sound, which I like, sounds like a bov on a turbo

I guess that would be a good thing, but that would make they're intake look like it performed really well, when it was really tricking the ECU.

1. Polished 6061 Aluminum vs powercoated galvanized steel
2. Seam welded joints (metal is all one peice instead of using welding rod as "glue") vs TIG welding
3. Thermal Flex silicone hose custom made vs Nappa Autoparts coolant hose
4. PRICE $109 vs $140
The aluminum piping has a slightly larger internal diameter than the galvanized steel Frankencar piping. However, the difference in performance from midpipe to midpipe would be negligible.

very easy to install... your basicly just taking out your stock air box and replacing it with a midpipe and air filter. Gains are proly about 5hp-8hp not too too sure youll gain alot of topend but loose very little low end.... ive got the berk intake and im about to get that midpipe when i get the extra cash... plus your engine will growl at WOT wich everyone loves hehe
wich everyone loves hehe

I need to get you guys a shot of the welds. They came out soooo nice!! I'm totally pleased with the quality my fabricator turns out for me. I'm sure glad that I got to know the right people in this car industry!

looks nice, i'm a fan of polished myself
FIRM fabrications integrated MAF eliminates breaks in the tubing walls. works on turbulence as the principal. similar to having your head ported & polished but did'nt port match the intake and exhaust manifolds. the ridge or step that is now created by enlarging one and not the other causes the air to tumble and decrease the air velocity. when you break the tubing wall and use hose clamps, there will be a slight gap, dip, or ridge even if you butt them together. it has been thoroughly tested. the stock fuel and ignition maps contained within the computer has the ability to adjust for descrepencies in airflow, low octane gas, limp-in mode when a sensor fails, etc...

I don't know what you are saying... as I understand, the MAFS has a tube of a given size that measures air flow with a heated wire at a single point. If you increase the size of the MAFS tube, more air will pass through the entire tube at the same given rate for the MAFS sensor. Therefore, you would be putting more air in the engine then the MAFS accounts for, ie LEAN. This will probably make more HP, but you will be tricking the computer and running lean, which COULD cause problems...

My setup leaned out my fuel mixture because I used a larger MAF tract which I have to compensate with extra fuel pressure.

I just think that if it does indeed change the amount of air the ECU see's, then it would be nice to know exactly how much. Maybe it's minor, maybe not.

cobymoby,
will this midpipe work to just replace the current rubber flex pipe, and still keep the stock airbox and filter?? i'm looking to improve flow, but don't want the sound associated with the open ended filters.

I'm pretty sure the ECU can adjust for variations in the MAF. It does this by monitoring the 02 sensors. Over time, I think it will adjust the value of a correction factor for the MAF readings . . . After all, if the ECU knows the amount of fuel added, and the amount of oxygen left after combustion, it can adjust the MAF readings to be properly calibrated . . .
