Sikky FRS / GT86 / BRZ LS Swap Headers Stainless Steel Long Tube 1 7/8" Primaries with 3" Merge Collector and Complete V-band Clamp Assembly sikkHDR021SS

Here’s the info on Sikky FRS / GT86 / BRZ LS Swap Headers Stainless Steel Long Tube 1 7/8” Primaries (sikkHDR021SS) — a popular choice if you’re doing an LS-engine swap into a Toyota 86 / Subaru BRZ / Scion FRS.

✅ What it is

• Designed specifically for Toyota GT86 / Subaru BRZ / Scion FRS chassis when doing an LSx (LS1/LS2/LS3/LS6/LS7) swap.  
• Helps you bolt up a full stainless-steel exhaust header setup that fits in the OE engine bay (RHD or LHD).  

🔧 Key Specifications & Features

• 100% stainless steel — high-quality 304 stainless steel for durability and corrosion resistance.  
• 1 7/8″ primaries — large-diameter primaries to support high flow and power potential.  
• 3″ merge collector with “merge bullets” — designed for high flow through the collector, improving scavenging and exhaust flow.  
• Pre-welded V-band flange — collectors come with V-band flange welded on, with the clamp and mating piece included. Makes for easier install / removal and a cleaner exhaust layout.  
• CNC stainless head flanges — precision-fit flanges for sealing and correct port alignment.  
• Comes complete — left and right headers, gaskets, bolts, V-band clamps/flanges, and offset steering rack bushings (to clear steering column) are all included.  
• Fitment — Works for both RHD (right-hand drive) and LHD (left-hand drive) GT86/BRZ/FRS.  

📦 What You Get in the Kit

• Driver-side and passenger-side headers
• Gaskets, hardware (bolts)
• V-band flanges + clamp
• Offset steering rack bushings (needed to clear steering column when the LS is installed)  

⚠️ Fitment / Usage Notes & Warnings

• The headers are designed around the full Sikky LS-swap kit (engine mounts, swap mount hardware, steering rack bushings, etc.). Using other manufacturers’ swap kits can lead to fitment issues — Sikky recommends using only Sikky components for guaranteed fitment.  
• Installation ideally requires a lift and some mechanical competence. It’s a proper LS swap rather than a “bolt-on bolt up” you’d get on stock 4-cylinder 86/BRZ.
• As with most full-headers for swapped LS engines, you’ll need to plan your exhaust (over-pipe / Y-pipe / cat-back) carefully: there isn’t a simple “direct-fit” cat-back for LS-swapped chassis in about 95% of cases. Many owners end up custom-fabricating or picking up aftermarket Y-pipes or full exhaust systems.  

💡 Why It’s a Good Option (Especially for You)

Given your background — you already appreciate performance cars, power, cornering, and prudent maintenance — this header set makes a lot of sense:

• It gives maximum flow for an LS swap (1 7/8″ primaries + 3″ collector).
• Stainless construction helps with corrosion resistance — important if you’re in a humid climate (Kuala Lumpur).
• Because it’s a “drop-in” header for the GT86 / BRZ chassis, it simplifies the LS swap compared to completely fabricating your own exhaust manifold.
• The drop-in nature also preserves the chassis’ agility and space — minimizing clearance issues if you also want to run suspension or performance handling mods.

🔎 Recommendations / What to Double-Check Before Buying

1. Pair with full Sikky LS-swap kit — engine mounts, crossmember, steering rack bushings, etc. Using random “swap kit” parts can cause fitment issues.
2. Plan exhaust routing — you’ll likely need custom or aftermarket Y-pipe + cat-back. Research what others have done (Reddit / forums) for LS-swapped FT86/BRZ conversions.
3. Use heat-resistant spark plug wires — because of the tight packaging and large primaries. Sikky recommends Taylor 79013 plug wires for best clearance.  
4. Professional installation preferred — a lift and some fabrication know-how will make the job significantly easier.
