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.

Blue Spring for the win!
Install was easy and the product gave instant results. Throttle response is better and my truck runs smoother. Who knew a little spring would change so much.

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 !

SINISTER 7.3 Intake elbow W/ boots
I purchased the SINISTER 7.3 Intake Elbow W/ Boots Kit. The only thing that I didn't like but I knew about before I ordered. Was that the kit doesn't come with the boots pictured. It comes with the upper & lower intercooler pipe boots. Not the plenum to intake boots & upper intercooler pipe boots that are pictured when purchasing. Othewise it was packed very well came with three stickers & instructions black and white however also you can find the color instructions online. Very easy to install and looks sharp was very pleased with my sinister experience

So was given multiple tracking numbers for one item that was confusing. Exhaust tip arrived fast but box was smashed and the tip dented. I had to roll the edges of the exhaust tip with channel locks to get it round again, so it would slide on my exhaust.

Hey! We would love to help out with this - if it was dented we would like to make a claim with the shipper and get a replacement out to you. I'm checking in with our customer service reps, but it is hard to find an order without a name. If you do not want to put your name on here, please reach out to us on the help center or give us a call (888) 966-6543. We stand behind our products and our customer service.
