Hooker: Exhaust Manifolds for GM LS

Now available with 2.5” outlets, these LS exhaust manifolds from Hooker offer improved flow and hug the engine block to be suitable for a variety of replacement and engine-swap applications. Their contoured design shunts the exhaust directly to the exit port for improved flow, while the cast-iron construction offers years of leak-free performance—with less under-hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.

Five finishes available: Natural Cast (8502HKR), Silver Ceramic (8502-1HKR), Black Ceramic (8502-3HKR), Titanium Ceramic (8502-4HKR), and Cast Iron Gray Ceramic (8502-5HKR).

Features

  • For GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired.
  • 5” outlet diameter for improved flow.
  • Nickel-plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware included.
  • High-silicon/moly ductile iron for durability and corrosion resistance.
  • Tight tuck design fits most popular chassis and offers a clean muscle car appearance.
  • Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans.
  • Five finishes: as-cast or four colored ceramic coatings.

NOS: 4-Bolt Throttle Body Nitrous Plate Kits for GM LS Engines

If you’re running a GM LS-based engine and would like to add up to 250 horsepower, complete nitrous kits from NOS inject a little more power into that stock engine or a lot more power into that custom-built hot rod. Kits include jetting for 100, 125, and 150 additional horsepower, while the plates themselves can flow enough nitrous for 250 big HP.

Available for 4-bolt drive-by-wire or cable-operated throttle bodies in 90mm and 105mm plate sizes, these are “wet” plates. The additional fuel is added though the nitrous system, so there are no requirements for an injector upgrade (but you should always make sure that your fuel delivery system is adequate to support the expected power levels).

Features

  • Add up to 250 HP to GM LS engines.
  • Available for 4-bolt drive-by-wire or cable-operated throttle bodies (90 & 105mm plates).

PROFORM: Wedge-Lock Header Bolts

Each PROFORM Class 12.9 (equiv. Grade 8) Header Bolt is permanently assembled with a pair of special wedge-locking washers. When the bolt is torqued to 28+ ft.-lb., the washers’ super-hardened external teeth bite into and grip the bottom of the bolt head and the top surface of the header. After being self-locked in this manner, any bolt-loosening rotation is blocked by a wedge-locking action created by the washers’ interfacing, matching cams. It’s an uphill climb: vibration that might ordinarily loosen the bolt actually increases the wedge-locking tension, securing the bolt even more. Because this design uses tension instead of friction, contact with oil actually facilitates the wedge-locking effect. When it comes time to change headers, PROFORM Header Bolts can be loosened with a normal wrench, lubricated, and reused.

Available in:

  • 0.984″ x 8 mm, 12 bolts (66754)
  • 1.181″ x 8 mm, 12 bolts (66755)
  • 1″ x 3/8″, 16 bolts (66756)
  • 3/4″ x 3/8″, 16 bolts (66752)
  • 3/4″ x 3/8″, 12 bolts (66751)
  • 1″ x 3/8″, 12 bolts (66753)
