Frequently Asked Questions
Q: Will an aftermarket exhaust void my Lexus IS350 warranty?
A: Modifying the exhaust system may affect your warranty if it causes damage. However, under the Magnuson-Moss Warranty Act, dealers cannot deny warranty coverage solely due to aftermarket parts unless they prove the modification caused the issue.
Q: How often should I replace the exhaust on my IS350?
A: Exhaust systems typically last 8–10 years or 100,000+ miles. Signs of wear include rust, leaks, or loud noises. Regular inspections can help catch issues early.
Q: Can I install an exhaust system myself?
A: Simple upgrades like carbon fiber covers are DIY-friendly. However, full exhaust replacements or flex pipe installations may require mechanical skills and proper tools. Consider professional help if unsure.
Q: Do I need to tune my engine after installing a new exhaust?
A: Not always. Stock ECUs often adapt well to aftermarket exhausts. However, for significant performance gains, a custom tune can optimize air-fuel ratios and throttle response.
Q: Are catalytic converters required on all exhaust kits?
A: Yes, in most regions, catalytic converters are mandatory for emissions compliance. Ensure any kit you choose is EPA or CARB approved, especially if you live in California or other restricted states.
