Professional Exhaust and Emissions Services You Can Trust

D & J's Automotive has been serving Olathe since 2008 as a locally owned, family-operated NAPA Gold Auto Center. Our ASE-certified master technicians bring years of specialized experience to every exhaust and emissions repair. We service most makes and models with the same commitment to honest, transparent communication that has built our reputation in the community.

We understand exhaust and emissions problems need immediate attention. That's why we have same-day diagnosis available for most vehicles, backed by our comprehensive 2-year/24,000-mile repair warranties and the NAPA Peace of Mind Warranty. Our digital inspections for $100 give you a clear picture of your vehicle's condition, helping us prioritize what needs attention first. Contact us today to schedule your service.
