Arrow Suzuki GSXR 600 750 2006-2010 4:2:1 Stainless Steel Collectors For Arrow Silencers 71334mi

The Arrow Racing Stainless Steel Collectors (Part Number: 71334MI) for the 2006–2010 Suzuki GSX-R 600 and 750 change the layout from stock to unleash the bike's actual potential.

If you are upgrading from standard OEM headers to this specific set, here are the main advantages you'll see:

1. Significant Power and Torque Gains (Up to +13 HP)

The stock header assembly contains a restrictive catalytic converter and heavy internal baffling. The Arrow 71334MI removes the catalyst entirely, streamlining exhaust scavenging. According to Arrow's dyno data:

• GSX-R 750 (06-07): Yields a massive gain of up to +13.00 HP and +6.57 Nm of torque when paired with an Arrow silencer.

• GSX-R 750 (08-10): Yields up to +8.00 HP and +2.84 Nm of torque.

• GSX-R 600 (06-07): Delivers a bump of around +3.00 HP and +2.55 Nm, smoothing out flat spots in the midrange.

2. The 4:2:1 Layout Advantage

Arrow uses a 4:2:1 design (4 pipes merge into 2, then into 1). Compared to a straight 4-into-1 racing layout, a 4:2:1 architecture is highly optimized for mid-range power and torque delivery. This makes the bike pull significantly harder out of corners on the track and feel much more responsive during street riding, rather than only packing a punch at the absolute top of the RPM range.

3. Major Weight Reduction

The OEM exhaust system on the K6–K10 generation of GSX-R models is notorious for being heavy, largely due to the under-engine "boom box" catalytic converter.

• Swapping the stock collector for this high-grade AISI 304 stainless steel unit drops the component's weight down to roughly 2.9 to 3.1 kg (depending on the exact model year pairing).

• Overall, completing the full system with an Arrow silencer can shave up to 5.1 kg (~11.2 lbs) off your machine, dramatically sharpening your bike's handling and side-to-side transitions.

4. High-End Construction & Precision Fit

Arrow uses CNC-machined components for all joints and connections to eliminate interior steps and weld slag. Because the welds are completely non-invasive, the inner diameter remains perfectly smooth, avoiding unnecessary internal drag on the escaping exhaust gases.

5. Highly Weather & Corrosion Resistant

The AISI 304 stainless steel alloy used has superb thermal and moisture resistance. Unlike cheap steel headers that warp, pit, or rust out from road grit, moisture, or chemical motorcycle washes, this alloy retains its structural integrity over intense heat cycles.

⚠️ Important Fitment Note: Because these collectors are designed for racing performance, they feature a 48mm outlet meant to slip directly into Arrow silencers (or an Arrow mid-pipe link like the 71382MI for the 08-10 models). They are not a direct drop-in swap for the stock muffler connection without modifications or matching Arrow link pipes. A proper ECU fuel map/tune is highly recommended after installation to optimize the new air-to-fuel ratio.
