Performance Headers Application: Porsche® 928 all, depending on engine Our 16v Headers fit all 16v motors from 1978-1986 and use a standard collector, as shown. Our 32v Headers fit all 32v motors from 1985-1995 and feature a merged collector, as shown. More HP, better bottom-end torque, and a richer sound are all benefits from opening the 928 exhaust up with a good system. Headers are the first part to that system - they replace the stock exhaust manifolds. These headers are made with 1 5/8" primaries and 3" collectors for excellent mid-range response and a strong upper end. These headers are available in raw steel or Jet-Hot coated. The Jet-Hot Sterling Silver Coating will extend the life of your headers by 20 times or more for street applications, and controls temps in the engine bay by reducing header-surface temps by almost 50%. Withstands temperatures up to 1000° F (peaks to 1200 F) and offers superior durability when compared to brush/spray on coatings. Will reduce engine bay heat, saving you money on plugs, wires, fan motors, water pumps and other heat-sensitive parts. And, because Jet-Hot is the only product to surface-coat both the inside and the outside of each pipe (no spray-on paint can do that) there is even a HP and torque increase caused by smoother exhaust gas flow. This finish is less likely to chip and rust than a ceramic coating, and more durable than a spray-on paint job. The Jet-Hot Sterling coating we use is exclusively formulated for headers and exhaust systems. All are UV and fuel resistant. Installation: Our Header kits come with everything you see listed below. Most owners can do it themselves in a day, the removal of your exhaust manifolds and installation of the headers requires some reasonable mechanical skills. What is included in this Kit:

Big-Port Headers (Performance Mid-Range Headers are also available) Application: 1987-1995 32v Porsche® 928 with modified motors

Just for Modified Motors! Our Big Port headers are especially designed for heavily-modified Porsche® 928 engines that need max power at wide-open throttle. Larger than our Performance Mid-Range Headers, these come port-matched to the 928 Motorsports CNC ported Big Valve Heads. These headers are an excellent choice for engines with big cams, big superchargers, and big valves.

Description: These Big-Port Headers are made with 1.75” primaries compared to the 1.625” primaries found on our Performance Mid-Range Headers. The collectors are also shorter, yet still fit the standard 3” outlet flange so they are compatible with all our performance exhaust products. These headers come unfinished, so you can weld on sensor bungs where you like, and finish them to please. Because of their size, expect a snug fit—solid engine mounts recommended.

Flow Comparisons: Compared to our Performance Mid-Range Headers, these headers have 18% more flow.

On a boosted engine: • •

5000 rpm boosted: Up from 823 CFM to `004 CFM, and increase of 180.9 CFM 6500 rpm boosted: Up from 1070 CFM to 1305 CFM, and increase of 235 CFM

On a naturally– aspirated (NA) engine: • •

5000 rpm NA: Up from 476.9 CFM to 581.8 CFM, an increase of 104.9 CFM 6500 rpm NA: Up from 620 CFM to 756.3 CFM, an increase of 136.3 CFM

Stainless Steel Single Exhaust Application: Porsche® 928 78-84 US Models Description: This exhaust system features a Magnaflow muffler for muscle-car sound and performance for years and years in maintenance-free stainless steel.

And the price? Less than the OEM exhaust pipe, forward muffler, rear muffler, and tailpipe that it replaces.

Emissions Compliant: Because it bolts-on to the back of your catalytic converter and does not alter it in any way, this exhaust is 50-states emissions legal. Replaces everything from the Cat-back in glistening, rust-free stainless steel. Just look at the pictures... Has a beautiful, deep sound; but not so loud that you cannot enjoy talking to the person seated next to you.

Stainless Steel Single Exhaust Provides a genuine increase in your HP too! Fitment Note: Some very early 928s have a bolt-in battery box, (1977, early 1978) instead of the normal welded-in battery box. These early cars may need to make a minor (less than 1 inch) trim to one corner of the battery box to prevent rattling of the exhaust pipe against the body.

X-Pipe cont. Finish: Available in Aluminized Mild Steel or a Stainless Steel for $110.00 more. Catalytic Converters: For those that live in locations that require that catalytic converters, we have located special highflow-rate Cats. The Cats are cut into the ends of this X-Pipe, and fit before your existing 928 exhaust system so that you do not have to do any cutting to your 928 Exhaust. These new all-steel Cats flow exceptionally well and only reduce your output compared to having no Cats at all by 6-8 HP (compared to having no cats at all). Ceramic Cats that we tested reduced the HP by as much as 15 HP! Headers: We are sometimes asked if the X-pipe can be used with Headers. Generally speaking, No. Not without a lot of cutting and custom welding. Headers and a free flow exhaust will yield up to 55 HP, but require a lot more $$ and work to install. The X-pipe is a bolt-in and allows you to keep the rest of your exhaust to save money.
