What is the main difference between an axle-back and a cat-back exhaust system?

An axle-back exhaust system replaces only the mufflers and exhaust tips, typically starting at the rear axle. A cat-back system replaces everything from the catalytic converter back, including the mid-pipe and mufflers.

Will this exhaust system make my car too loud for daily driving?

The Invidia Q300 series is designed to provide an improved exhaust note that is sporty and noticeable during acceleration, but generally remains comfortable and free of excessive drone during cruising speeds.

What is included with this Invidia axle-back exhaust?

This kit includes the Invidia Q300 axle-back exhaust section, which contains the mufflers and tips. It also comes with any specific hangers and gaskets required for installation on your Lexus GS.

Product Details

This Invidia Q300 axle-back exhaust is made for the 2007-2011 Lexus GS350 and the 2006 Lexus GS300. If you're looking to change the sound and look of your GS without a full cat-back system, an axle-back like this is a great option. It replaces the mufflers and tips, giving you a more aggressive exhaust note and a sportier appearance out back.

Invidia is known for making well-built exhaust components, and the Q300 line is designed to offer a noticeable improvement in sound without being overly loud or droney. This system is constructed from polished stainless steel, which helps resist corrosion and keeps it looking good for a long time. The polished finish also adds a clean, high-end look to the underside of your car. Installation is typically straightforward, as axle-back systems bolt directly to the factory exhaust piping just ahead of the rear axle, meaning no welding or cutting is usually required.

When installing this axle-back, you'll want to ensure you have a way to support the rear of the vehicle safely. The kit includes the axle-back section and any necessary hangers or gaskets that are specific to this application. It's a popular choice for GS owners who want a more satisfying exhaust tone that complements the luxury feel of the car, offering a deeper rumble during acceleration and a quieter presence during cruising.
