Fabspeed Motorsport: 996 Maxflo Sport Headers
Fabspeed Motorsport updated the Maxflo Sport Headers for the 996 Carrera 2/4/4S which now feature the investment cast flanges for improved accuracy and longevity. These headers maintain the investment cast 3-into-1 high-velocity merge collector to improve exhaust scavenging compared to the OEM style collector. Constructed from 14-16 gauge T304 stainless steel with one piece equal length C.N.C. mandrel bent primary pipes, the Maxflo Sport Headers feature 44.5mm primary pipes compared to the 42.5mm OEM units. The outlet is a true 2.25"/57.2mm compared to the 50mm outlet of the OEM header. Composite gaskets are included with the Sport Headers and these units are a direct replacement for the OEM headers. Please PM or email ( Joey@fabspeed.com ) for more information and special 6Speed member pricing.
- Fit all 996 Carrera 2/4/4S Vehicles 1999-2004
- 14-16 gauge T304 stainless steel C.N.C. mandrel bent equal length primary pipes.
- Investment cast flanges and 3-into-1 high-velocity merge collector.
- Direct bolt-on replacement with no Check Engine Lights.
- Will bolt directly to the OEM catalytic converters or any aftermarket sportcat/catbypass pipe designed from the OEM specs.
- Includes composite gaskets for a leak proof seal.
- Backed by Fabspeed's Lifetime Limited Warranty.

Not sure just using a bigger diameter pipe makes sense considering exhaust velocity etc. If it was a huge advantage, when I would have thought Porsche would have done it factory since they could pick any diameter they wanted. My guess is more of a power shift, no gains over the whole curve.

A couple of years ago out of curiousity, I bought a pair of ebay headers that were plumbed almost identical to these,equal length tubes,nice welding,ss,etc. I dyno'd and lost low end TQ and HP, things did relocate to higher rpm, but the TQ was still less. I drive a tip,and loss of TQ low end isn't good. I agree that if Porsche wanted a different configuration that would create more power through out the band they would of done so. Same effort to bend and weld one to another. A guy actually wanted my headers after I posted info,go figure. Fab makes nice stuff, not trying to poo poo their effort, just not for me.

do you still have that dyno... I'm curious as to how much the torque curve shifted and what the values were...

Hardback I just sent you a PM with the price.
I just checked the dyno database and there is no data for just the Sport Headers. We had these installed with full exhaust/intake packages, not just an isolated Sport Header. The power shift was predominately at the top end, just north of 3000RPM with the full Maxflo Exhaust package installed.

I had heard great things about Fabspeed's "customer service," so I have to admit to being startled by my appalling experience with the company.
I initially telephoned Fabspeed on Fri., Dec. 16, 2011, with the intention of ordering a new exhaust system for my Porsche 997S. I was told "everyone's out to lunch." It was 11:00 a.m. The statement was prophetic. I was told someone would call me back. No one did. I wrote an email of inquiry to General Manager Alex Kononchuk the following day. It took him 30 DAYS to respond.
I telephoned Fabspeed again on Mon., Dec. 19, spoke with "Dave," and he recommended the 997-S Catbypass X-Pipe ($795), the 997-S Muffler Bypass Pipes ($300), and the 02 Extender Elbows ($150), which he told me would eliminate the dreaded "Check Engine" light, when removing the car's catalytic converters. I paid for the order with a credit card. He sent me an online invoice later that day with the Fedex tracking numbers.
A week later, the order was still sitting at Fabspeed. I was told there was a "mixup" with Fedex. The parts arrived 10 days late.
Installation began in early January. No instructions were included in the shipment. My shop was unclear on the installation process and several phone calls to Fabspeed went unreturned. Turns out, Fabspeed had shipped incorrect parts, which wouldn't fit. Instead of the "997-S Muffler Bypass Pipes," Fabspeed sent "CUP Bypass Pipes." They had to be cut and welded. Oh, and the "Check Engine" light came on immediately, so the 02 Extender Elbows ($150) were worthless.
Literally dozens of telephone calls and emails later, General Manager Alex Kononchuk offered to credit me for the incorrect pipes...IF I bought the "Supercup Exhaust" mufflers ($1,050). I agreed, with the understanding that I HAD to have the parts in hand within 30 days. Alex promised to have the order shipped "within the next couple of days." That was the middle of January.
By February 6, with no contact from Fabspeed, I began to get nervous. After several rounds of phone tag, I finally reached Alex Kononchuk, who admitted to "zoning out" and forgetting our conversation three weeks earlier. He promised to get the order shipped "later today." Another week passed. I wrote to Fabspeed President Joe Fabiani. He never responded.
With a race weekend fast approaching, I began calling Fabspeed again. At various times, I was told Alex Kononchuk was "in Colorado and didn't have a phone signal," or was "in Chicago at a trade show." No one could find any record of my order.
Kononchuk finally left a voice message on my cell (at 11 o'clock at night) apologizing for the confusion. He said he had suffered a shoulder injury and was undergoing rehab. This was his excuse for not shipping the "Supercup Exhaust." He assured me there was still time to ship the order and apologized for the screw-up. "There's absolutely no excuse for this," he said. "We'll do anything it takes to make it right."
Four days later, Kononchuk left a late night voicemail, saying that he had some "not so good news." There were no "Supercup Exhaust" units in stock and the shop would have to "build a set," he said. They would not be delivered in time for the race.
More than two months had passed since my initial contact.
I'm certain plenty of people have had satisfying experiences with Fabspeed. I did not.
