5 of 5 Peppy & rumbling sound on my 2013 Lincoln MKT May 15, 2023
Reviewed by: Rakesh from California  
Got this "10-19 Flex MRT Sport Touring Axle Back" from Vivid racing and I got in touch with MRT team for my technical questions. The team is great with Dave helping me out on my concerns over the fitment. I was able to do this DIY in my garage, the instructions are straight forward. Requires a cut-off tool, hacksaw to get the cutting done.

My MKT now has a very sweet rumble at idle and not loud at all when accelerating. I can hear to that rumble inside the car cabin which makes you give that sudden throttle every now and then. Happy with the support and quality of the product !!!

First off, this exhaust sounds really good. Has a nice, aggressive idle from the outside but isn’t obnoxious. Sounds great passing cars on the highway too! Super easy install to do for yourself at home as well. Overall super happy with the quality of the product and will be shopping here again for future vehicles!

Installed these with a friend and took about 30 min. All you need is a saws all, a good level eye and a couple beers. Tone is nice and always enjoy the cold starts.
