This company went above and beyond to ensure that the auto part arrived. Excellent customer service—they even dealt with the UPS snags.

Muffler delete pipe is too long

Exhaust pipe is too long. Is not a direct replacement. Have to cut 3” off existing exhaust in order to fit. Good quality material.

Thanks for your feedback! We’re glad to hear you’re happy with the quality of the material. Because some of our exhaust parts are designed as universal fit, the length can vary slightly and may require trimming during installation. Fitment can also differ depending on model year and configuration. If you’d like, our team can help double-check fitment for your specific truck and walk you through the install. Please feel free to reach out through our Help Center so we can make sure everything is dialed in for you.

Hey Gauge - we apologize on the delay. We had one piece of the kit on back-order and unfortunately that delayed out your order. We do send a back-order email and it is usually followed up with a phone call. We will use your feedback to better our system. It does show that your order went out on 7/25 and should have been delivered. Please reach out to us directly with any issues. Thank you for your business.

I was excited to get parts for my new truck . I placed 2 orders at different times only to be notified they were both on back order . The thing I don’t like was that they took my money knowing they didn’t have the product ,I left an email and they did call me back . She said next time call sales because the website doesn’t have a counter. I did find what I wanted through Amazon but it ended up costing me more money !
