Give your Pontiac G8 the V8 sound it should have with this 3-inch axle-back exhaust from Bull Boost Performance. The straight-through design opens up the sound of the 6.0L or 6.2L engine, while the built-in J-pipes help cut down on drone inside the car.
This system replaces the restrictive factory rear mufflers and finishes the back of the car with four polished 3.5-inch exhaust tips. It has an aggressive tone when you get into the throttle without leaving you stuck with constant drone every time you take the car on the freeway.
Features
- Dual 3-inch high-flow exhaust piping
- Four polished 3.5-inch exhaust tips
- Integrated J-pipes help reduce interior drone
- Made from durable 304 stainless steel
- Replaces the factory rear muffler sections
- Aggressive V8 exhaust note
- Bull Boost rates the sound at 8 out of 10
- Direct bolt-on installation with no cutting required
Vehicle Fitment
- 2008 Pontiac G8 GT 6.0L V8 with GXP rear valence
- 2009 Pontiac G8 GT 6.0L V8 with GXP rear valence
- 2009 Pontiac G8 GXP 6.2L V8
Please Note: The Pontiac G8 GT requires a GXP-style rear valence to provide the correct openings for the quad exhaust tips. This system will not fit a GT with the standard rear valence unless the valence is changed.
Installation
This axle-back bolts to the factory exhaust connections and uses the original mounting locations. Cutting and welding are not required. Check the position of all four tips before tightening the system so they sit evenly in the rear valence.
Pairs Well With
- JBA Shorty Headers for Pontiac G8 GT 6.0L V8 – Improve exhaust flow ahead of the axle-back while adding more V8 sound and throttle response.
- Weapon-R Secret Weapon Intake for Pontiac G8 GT – Help the 6.0L breathe better from the other end and add more intake sound when you get on the throttle.
- Whiteline Rear Sway Bar End Links for Pontiac G8 – Tighten up the rear suspension and replace worn factory links while upgrading the car.
