Customer Reviews
Reliable for Turbo Back Exhaust
This was my third order from KMS Motorsport, this time for a Turbo Back Exhaust System. As usual, the quality was top-notch, consistent with my previous purchases of an Air Intake System and some Wheel Spacers. They always deliver on time, and their products hold up well. It's why I keep coming back.
Great value on brake pads
I was looking for some new Performance Brake Fluid and Brake Pads and found KMS Motorsport. The price was really competitive, especially with a newsletter sign-up offer I found. I usually shop around a lot for car parts to get the best deal, and this felt like a solid win. The shipping was reasonable and everything arrived well-packaged. Happy with the savings and the quality.
Good quality, minor shipping hiccup
I ordered a set of Lowering Springs and the quality seems great for the price. Installation was straightforward. The only small issue I had was that delivery took 5 days to reach Denver, which was a little longer than I expected, but it wasn't a huge deal. Overall, I'm satisfied with the purchase and the springs look good on the car.
Detailed review of ECU software and support
I purchased the ECU Software for my Ford Focus ST a few weeks ago. The ordering process on the website was quite simple and I received a confirmation email promptly. The instructions for flashing the ECU were clear, though I did have a question about the specific version for my car, which customer service answered within a few hours via email – that was helpful. After installation, the car feels much more responsive, and I've noticed a definite improvement in power delivery, especially in the mid-range. It took about 3 days for the software to be available for download after purchase. Overall, the experience was smooth, and the performance upgrade is tangible.
Awesome Cat Back Exhaust!
I just installed the Cat Back Exhaust System I got from KMS Motorsport and I couldn't be happier! The sound is incredible and it looks fantastic on my car. Shipping was super fast too. I'm definitely buying from them again for my next upgrade and telling all my friends about it!

Is the Thunderstorm exhaust like, ridiculously loud? Don't want to annoy my neighbors every morning.
Thinking of getting the Thunderstorm exhaust for my ST, but I'm in California. How long does shipping usually take to the US?
Anyone know if KMS does any kind of Black Friday deals for their ECU tunes? Been eyeing one for my RS.
Can you use more than one discount code at checkout? Got a club discount but also saw a newsletter signup offer.
Do they offer any financing options for bigger purchases like a full exhaust system or turbo upgrade?
