What is the main difference between a resonated and non-resonated mid-section?

A non-resonated mid-section, like this one, has a straighter pipe with no internal baffling to quiet the exhaust. This allows for a louder, more raw engine sound. A resonated mid-section includes a muffler or chamber to reduce sound levels and drone.

What other parts do I need to complete the exhaust system?

This is a mid-section only. You will need to pair it with a compatible cat-back exhaust system or other ISR Performance exhaust components, such as their muffler section, to create a complete exhaust system from the catalytic converter back.

Is this exhaust system legal in all states?

No, this ISR Performance Series II non-resonated mid-section is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're looking to get a more aggressive exhaust note from your 1989-1994 Nissan 240sx S13, this ISR Performance Series II non-resonated mid-section is a solid option. This part replaces the factory connecting pipe and muffler section, giving you a straighter path for exhaust gases to exit the vehicle. Because it's non-resonated, it will allow more of the engine's natural sound to come through, creating a louder and more direct exhaust tone.

This mid-section is constructed from durable stainless steel, which holds up well against corrosion and the heat generated by the exhaust system. It's designed to fit directly onto your S13 chassis, making installation straightforward if you're comfortable working with exhaust components. This piece is intended to be paired with other ISR Performance exhaust parts or a compatible aftermarket cat-back system to complete the setup.

Keep in mind that this part is not CARB approved and cannot be shipped to California. It's a good choice if you're aiming for a louder, sportier sound and are building a custom exhaust system for your 240sx.
