Premium SUS304 Stainless Steel:

The N1 Evolution-X midpipe is constructed from premium SUS304 stainless steel, which provides excellent corrosion resistance and durability. SUS304 is a high-quality stainless steel grade that withstands the extreme heat and corrosive environment of the exhaust system, ensuring the midpipe will last for years without rusting or deteriorating.

60.5mm Piping for Improved Flow:

The 60.5mm (2.38 inch) diameter piping provides improved exhaust flow compared to the restrictive factory midpipe. This increased diameter reduces backpressure, allowing the engine to breathe better and potentially improving power output. The improved flow is especially beneficial when combined with other exhaust modifications like a cat-back system.

Resonated Design - No Drone:

The resonated design includes an internal resonator that reduces exhaust drone during highway cruising. This makes the N1 Evolution-X perfect for daily driving, providing an aggressive sound when you want it without the annoying drone that can make long drives uncomfortable. The resonator is carefully tuned to eliminate drone frequencies while maintaining the deep, sporty exhaust note.

Weight Reduction:

The N1 Evolution-X midpipe is lighter than the factory unit, contributing to overall weight reduction. While the weight savings may seem small, every pound counts when it comes to performance and handling. The reduced weight also puts less stress on exhaust hangers and mounting points.

Deep, Aggressive Exhaust Note:

The midpipe delivers a deep, aggressive exhaust note that enhances the driving experience without being obnoxiously loud. The sound is sporty and refined, perfect for enthusiasts who want their IS to sound as good as it looks. The resonated design ensures the sound remains pleasant and drone-free during normal driving.

Direct Bolt-On Fitment:

The N1 Evolution-X midpipe is engineered specifically for AWD Lexus IS models, providing direct bolt-on fitment using factory mounting points. No cutting, welding, or modifications are required. The midpipe connects to the factory downpipe and mates with the factory or aftermarket cat-back exhaust system.

Why APEXi N1 Evolution-X?

The N1 Evolution-X series represents APEXi's premium exhaust line, combining race-inspired performance with street-friendly characteristics. The Evolution-X name comes from APEXi's motorsport heritage, where their exhaust systems have been proven in the most demanding racing conditions. This midpipe brings that same quality and performance to your daily driver.

AWD Models Only - Important:

CRITICAL: This midpipe is designed specifically for AWD (all-wheel drive) Lexus IS models. It will NOT fit RWD (rear-wheel drive) models due to different exhaust routing and AWD component clearance requirements. Before purchasing, verify that your IS is an AWD model. Check your VIN or look for AWD badging on the vehicle.
