Kia Stinger 3.3T - Ultimate Performance HFC Downpipe + Mid Pipe Combo Kit

Aside from the removal and installation of the nuts securing the downpipes to the turbo everything was smooth. Probably much easier with a lift bit it was doable. The sound is fantastic! The power add is remarkable!

Just like many of you reading this review I placed a few items in my cart and let them sit there for a bit adding more items and taking some out. After a few hours of thinking about the order I was about to place, I finally committed and ordered them. One of the parts ordered is the Ultimate Performance Primary and Secondary cat kit. Shipping price was reasonable and actually came fairly quick. I went to work so I could install them, taking the old ones out is certainly easier than installing the new ones that I had just ordered. Luckily I am a Kia Certified Master Technician so I have all the tools and a lift at my disposal. Needless to say after trimming the driver side secondary pipe about 2. 5 inches and modifying one turbo exhaust nut to fit it has been installed. I am very pleased with the quality of the stainless steel used as well as the quality of the welds. I should also mention they sound great and I can’t wait to get the cat back installed next. A few days later I received an email from the K8Stinger Store to leave a review about the parts I had recently ordered. Instead of leaving a review at that moment, I decided to draft an email to the company explaining my experience with their direct bolt on kit. I kid you not literally 3 minutes after sending that email I get a call from K8Stinger Store. In fact the owner of the company reached out personally to investigate what had happen with my order. After a pleasant an lengthy chat it was agreed upon that in fact I had placed the order for an AWD kit and not the RWD kit which is the one needed for my application. Not only did he go into detail about how the site mechanics work but also was able to give me statistical data of how many units were sold, zero returns and where and how they are made. I was even given contact information for the facility that produces this kit. At the end of the day I learned a valuable lesson. Always double check before you check out. Also pay attention to those follow up email from companies which also show the contents of your order. I had about 3-4 chances to catch my mistake before it shipped and I didn’t fully pay attention. I was also given an option to return the product so that I could receive the correct one I needed as long as they were not installed. Being as I have already installed them and plan to add the cat back system in the rear future it was not a big issue for me to keep the AWD kit and I was able to make those slight modifications and make everything work out. I can say this is a first, where I have sent an email to a company expressing concerns or issues with a product and the owner personally reaches out to rectify an issue. I’m even more happy to support such a unique company like the K8 Stinger Store. Built from the ground up by passionate car enthusiasts.

The sound became deep and aggressive , I like it
