Stage 2 Bundle
One-Click Horsepower: Curated Stage 2
Bundles for the Dodge Magnum
Hand-picked by FastHemis for the 2005–2008 LX Magnum wagon — 5.7L Hemi and 6.1L SRT8. Each bundle combines an aFe cold air intake, Ripp high-performance coil packs, E3 spark plugs, a performance exhaust system, and a throttle body upgrade for bolt-on gains up to +70 HP — no tune required.
Important
What to Know Before You Buy
What Is a Stage 2 Bundle?
Everything in Stage 1 (cold air intake, high-performance coils, spark plugs) plus a cat-back exhaust system and throttle body upgrade. Five components working together for maximum bolt-on gains — no tune required, safe for stock PCM. Stage 2 adds exhaust flow and throttle response on top of the airflow and ignition improvements from Stage 1.
Why Buy the Bundle?
Each Stage 2 bundle is hand-picked by FastHemis specialists for your exact engine. All five components are confirmed compatible with the 2005–2008 Magnum, tested together, and priced better than buying individually. One click, one shipment — no sourcing five different products, no guesswork on fitment or compatibility.
Installation
DIY-friendly, 3–5 hours total. Intake, coils, and plugs: ~2 hours. Throttle body: ~30 minutes. Exhaust: ~1–2 hours (lift recommended). Basic hand tools, no wiring, no tuning. E3 plugs come pre-gapped. The cat-back is the most involved step on a wagon — jack stands or a lift make hanger alignment easier.
Warranty & Emissions
aFe intakes are 50-state legal. Ripp V6 coil packs carry CARB certification (EO: D-705-2) where applicable; HEMI coil packs are emissions-neutral with E3 plugs. Exhaust systems are for off-road/competition use — check local regulations. Bolt-ons do not void your factory warranty under the Magnuson-Moss Warranty Act unless they cause a related failure.

The Scoop
Why this bundle? The Magnum R/T 5.7L shares the LX architecture with Charger and 300C, and it responds the same way to a full Stage 2 path. This bundle targets +70 HP combined: aFe MagnumFORCE intake, Ripp MV8-CPK coils, E3.66 plugs, aFe MACH Force-Xp cat-back (49-42024), and 90mm throttle body — air in, combustion, and air out without touching the PCM.
What’s included? aFe MagnumFORCE Stage-2 Intake System (54-10712), Ripp HEMI High Performance Coil Packs (MV8-CPK, 8-pack), E3 Spark Plugs (E3.66, 16 included), aFe MACH Force-Xp Cat-Back Exhaust Polished Tips (49-42024), and aFe 90mm Throttle Body Kit (46-39112). Confirmed for 2005–2008 Dodge Magnum 5.7L Hemi.
Is this the same kit as the LX Charger / 300C 5.7L? The component set matches our curated Stage 2 LX 5.7L packages — Magnum, Charger, and 300C of this era use the same proven intake, coils, plugs, cat-back, and throttle body pairing for the 5.7L HEMI.
The aFe MACH Force-Xp cat-back (49-42024) is the halo piece for this 5.7L Stage 2 bundle. Built from 304 stainless with 3-inch mandrel-bent tubing, it replaces the factory exhaust path from the cats back for better flow and a deeper HEMI note — wagon or not, the Magnum deserves to breathe.
With the MagnumFORCE intake, 90mm throttle body, Ripp coils, and E3 plugs, the system delivers +70 HP combined — all bolt-on, typical 3–5 hour install, no tune.

The Scoop
Why this bundle? The Magnum SRT8’s 6.1L HEMI is the hottest factory offering for the wagon; Stage 2 adds +70 HP combined with MagnumFORCE intake, Ripp coils, E3 plugs, ARH 3-inch cat-back, and 90mm throttle body. The ARH system is tuned for high-flow V8 applications on the LX platform — perfect for an SRT8 that hauls cargo and passes.
What’s included? aFe MagnumFORCE Stage-2 Intake (54-10712), Ripp HEMI Coil Packs (MV8-CPK, 8-pack), E3 Spark Plugs (E3.66, 16 included), American Racing Headers Cat-Back Exhaust System, and aFe 90mm Throttle Body Kit (46-39112). Confirmed for 2005–2008 Dodge Magnum 6.1L SRT8.
Same intake as the 5.7L Magnum bundle? Yes — the 54-10712 MagnumFORCE covers both 5.7L and 6.1L for this generation. The exhaust differs: SRT8 gets the ARH cat-back matched to higher exhaust volume.
The American Racing Headers cat-back is the halo upgrade for the 6.1L Stage 2 bundle. Three-inch 304 stainless tubing and Pure Thunder mufflers replace the factory exhaust for a major jump in flow and a commanding SRT exhaust note behind the wagon.
Together with the MagnumFORCE intake, 90mm throttle body, Ripp coils, and E3 plugs, you get +70 HP combined with no tune — ideal for Magnum SRT8s that see street and strip duty.
Common Questions
Frequently Asked Questions
Do I need a tune for the Stage 2 bundle?
No. All five components — the aFe intake, Ripp coils, E3 plugs, cat-back exhaust, and throttle body — are designed to work with the stock PCM. No tuning, no flashing, no ECU modifications. The gains come from improved airflow, stronger spark, more efficient combustion, and unrestricted exhaust flow within stock parameters.
Will the Stage 2 bundle void my factory warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty for aftermarket parts. The aFe intake is 50-state legal, and coils and plugs are emissions-neutral. Exhaust systems and throttle bodies are for off-road/competition use — check your local regulations. Keep your stock parts if you need to revert for dealer visits.
Why buy the Stage 2 bundle instead of parts individually?
The bundle is priced lower than buying each component separately, ships in one order, and every part across all five components is confirmed compatible with your 2005–2008 Magnum and engine. No sourcing five different products from five different brands, no fitment guesswork, no risk of ordering the wrong part number. One click, one shipment, one install weekend.
Can I install this myself?
Yes. All five components are designed for DIY installation with basic hand tools. Intake swap: ~1–2 hours. Coils and plugs: ~1–2 hours. Throttle body: ~30 minutes. Exhaust: ~1–2 hours (lift or jack stands recommended). Total install time is 3–5 hours for the full Stage 2 upgrade. No wiring, no tuning, no special equipment.
What’s the difference between Stage 1 and Stage 2?
Stage 1 is intake + coils + plugs (3 components). Stage 2 adds a cat-back exhaust and throttle body (5 components) for +70 HP combined on both Magnum engines in this guide. The exhaust opens up exhaust flow and the throttle body reduces intake restriction, working together with the Stage 1 components for higher combined gains.
What comes after Stage 2?
After Stage 2, the next performance tier includes long-tube headers, high-flow mid-pipes, a custom tune, or forced induction (supercharger kits). Your Stage 2 foundation — intake, coils, plugs, exhaust, and throttle body — supports and complements those modifications. The Ripp coils are compatible with forced induction, and the 90mm throttle body supports supercharger kits out of the box.
