Long tube headers and X-pipe kit for 2008-2013 Cadillac CTS-V

SS304 stainless steel long tube header for CTS-V 6.2L LSA

Long tube headers installed on 2008-2013 Cadillac CTS-V engine bay

Long Tube Headers for 2008–2013 Cadillac CTS-V | X-Pipe Kit

Engineered and manufactured in-house for the 2008–2013 Cadillac CTS-V 6.2L LSA V8, this long tube header and X-pipe package is built for distributors, importers, and professional tuning workshops. Available as a catted (200-cell high-flow cat) or catless off-road configuration. Full OEM/ODM support available — custom tube diameter, finish, and private labeling included.

✅ True Long Tube Design — Primary tubes run the full length from the exhaust port flange to the merge collector — not a mid-length shortcut. This maximizes exhaust pulse scavenging efficiency, delivering measurable torque and horsepower gains across the entire RPM range.
✅ SS304 Stainless Steel + Precision TIG Welding — Fabricated from 304-grade stainless steel and joined with TIG welding using brass filler rod. The result is a heat-resistant, crack-proof joint that outlasts 409-steel competitors under sustained thermal cycling.
✅ 3″ Merge Collector with CNC-Machined Scavenger Spikes — The collector cone is CNC-machined to tight tolerances, optimizing exhaust gas velocity and improving throttle response. Compatible with both forced-induction and naturally aspirated LSA builds.
✅ Catted or Catless X-Pipe Package — Your Choice — Ships standard with a 200-cell high-flow catalytic converter for street-legal builds, or as a catless off-road configuration for track and race applications. Both options available from a single factory source.
✅ Bolt-On Direct Fit — Complete Hardware Included — Every kit includes pre-welded O2 sensor bungs, grade-rated bolts and nuts, and high-temperature gaskets. No modifications required — reduces installation labor and makes bulk stocking straightforward for distributors and resellers.
Engineered at the factory level for the 2008–2013 Cadillac CTS-V 6.2L LSA V8, this long tube header and X-pipe package is built for distributors, performance parts importers, and professional tuning workshops who demand consistent quality at scale.Unlike retail-assembled kits, every unit is manufactured in-house — from raw SS304 tube cutting to final TIG welding and collector machining — ensuring dimensional accuracy and batch-to-batch consistency. Available as a catted package (200-cell high-flow catalytic converter) or catless off-road package, with full OEM/ODM customization support including tube diameter, coating finish, and private labeling.

CTS-V Long Tube Headers & X-Pipe: Full Description

What Makes This a True Long Tube Header — Not a Mid-Length

The market is full of “long tube” claims. This product is a genuine long tube header design: primary tubes extend fully from the exhaust port flange to the 3-inch merge collector, maximizing exhaust gas velocity and scavenging effect across the entire RPM band. Dyno testing on the 6.2L LSA platform consistently shows +15–25 whp gains over stock manifolds when paired with supporting modifications.

SS304 Material & Welding Standard

All tubes are fabricated from 304-grade stainless steel (SS304), which offers:

Chromium content ≥18%, nickel ≥8% — superior oxidation resistance at sustained exhaust temperatures (600–900°C)
Mandrel-bent tube geometry — no flow restriction at bends
TIG welding with brass filler rod — crack-resistant joints under thermal cycling

This is the same material grade used by premium North American header brands, manufactured at a fraction of the cost through direct factory supply.

X-Pipe Package: Catted vs. Catless — Which to Choose?

	Catted X-Pipe (200-cell)	Catless / Off-Road X-Pipe
Emissions	Street-legal (most regions)	Race/off-road use only
Sound Level	Moderate — refined tone	Louder, more aggressive
Flow Restriction	Minimal (high-flow cell)	Zero restriction
Best For	Street performance, daily tuning builds	Track, drag, dedicated race cars
Custom Options	100/300-cell available	Straight-pipe option available

Both configurations use 3-inch diameter X-pipe tubing with precision-welded collector connections, ensuring fitment consistency for the CTS-V chassis.

Manufacturer Advantage: Why Source Direct

As a factory manufacturer, we control every stage of production:

Raw material sourcing → SS304 certified mill certificates available
In-house CNC machining → collector spikes, flanges, O2 bungs
Quality inspection → dimensional check, weld integrity, leak test per batch
MOQ flexibility → suitable for distributors starting at small trial orders
Lead time → standard production 15–25 days; expedited available

For importers and distributors looking to source performance exhaust headers direct from manufacturer, this product line offers the most competitive landed cost in its category.

❓ FAQs — 2008–2013 Cadillac CTS-V Long Tube Headers

Q1: What is the difference between catted and catless X-pipe for CTS-V headers? A: A catted X-pipe includes a high-flow catalytic converter (typically 200-cell) that reduces emissions while still improving flow over stock. A catless (off-road) X-pipe removes the cat entirely for maximum exhaust flow — suitable for track use or regions without emissions testing. We offer both configurations, with custom cell counts (100/300) also available.

Q2: Will these headers fit both the CTS-V Sedan and Wagon? A: Yes. The 2008–2013 CTS-V Sedan and Wagon share the same 6.2L LSA engine and exhaust flange geometry. Our headers are designed to fit both body styles with the same bolt-on installation.

Q3: What primary tube diameter should I choose — 1-7/8″ or 2″? A: For street-driven builds or mild forced-induction setups, 1-7/8″ primaries offer excellent low-to-mid RPM torque. For high-boost or high-RPM track builds, 2″ primaries improve top-end flow. Our sales team can advise based on your customers’ typical build profiles.

Q4: Do you provide mill certificates for SS304 material? A: Yes. We provide SS304 material test reports (MTR) upon request for B2B orders. This is standard for our export documentation package.

Q5: What is the MOQ and lead time for wholesale orders? A: MOQ and lead time vary by configuration. Contact our team directly for a tailored quote — we support both trial orders and full container loads.

Q6: Can you do private label / OEM branding on the headers? A: Yes. We support laser-engraved branding, custom packaging, and full OEM/ODM programs. Minimum order thresholds apply for branded production runs.

Q7: Are these headers compatible with stock O2 sensors? A: Yes. Each header set includes pre-welded O2 sensor bungs in the correct positions for the CTS-V’s stock sensor configuration. No extensions or adapters required for standard installations.
