Mufflers repair service near Tinley Park, IL

I have high expectations for anyone who works on my vehicles and Rennology was up to the task. They are very professional and completed the work in a timely manner.

I have used this shop several times over the years they have always been very professional and prices reasionable. I have also recommend them to several friends and family

I brought my car in for a diagnostic and they gave me over a quote for over $3,000 in repairs. I took it down the street for a 2nd opinion and half the things they said were wrong was a lie. Had my car repaired where I got thr and opinion for less than 1k. It's been 6 months and not a single problem. A dealership and repair shop run by conmen. Color me surprised (NOT)

Very honest people and great customer service

Great service. Received discount without coupons. Was picked up when service was done. I felt like I wasn't taken advantage of being a women and the price was fair. Thank You for doing a great job. M VD
