Lexus IS500 Exhaust Master Buyer’s Guide: Axleback, Midpipe, Catback, Headers, Sound Level, and Price Tier Comparison

The Lexus IS500 has a growing number of exhaust options available, ranging from simple axleback systems to midpipes, full catback exhausts, valved systems, titanium systems, stainless steel systems, and headers.

This guide was put together as an informational resource to help compare Lexus IS500 exhaust options by brand, exhaust type, sound level, price tier, material, and general use case.

Important Notes

Sound levels are general estimates. Final volume depends on the full combination of parts, including axlebacks, midpipes, headers, catalytic converters, and resonators.

Price tiers are simplified into Value, Mid Range, and High End. They are intended only as general comparison points, not exact pricing.

Some exhaust components, especially headers and catalytic converter-related parts, may affect emissions compliance depending on location. Always check local regulations

NOVEL Carbon Fiber Aerodynamics Kit Installation Guide for Lexus GS F

Official Instructions:

The NOVEL Carbon Fiber Aerodynamics Kit is one of the cleanest exterior upgrades available for the Lexus GS F. The kit adds a more aggressive and refined appearance while still following the factory body lines of the vehicle.

This installation overview covers the main NOVEL aero components for the Lexus GS F, including the front lip spoiler, side spoilers, rear under spoilers, and rear diffuser. The installation is straightforward for an experienced installer, but it does require careful test fitting, drilling, surface preparation, and hardware installation.

This is not simply a peel-and-stick installation. NOVEL’s instructions call for test fitting, marking hole locations, drilling, installing supplied hardware, applying double-sided tape, and securing the components with bolts, clips, nutters, nutter rings, or tapping screws depending on the part.
