Didn't realize you're the middle man, no point in ordering from you if I have to wait for you to get the product when I could've had it directly from the manufacturer in half the time, didn't want to leave a review but you insisted

Thanks for sharing your feedback. We reviewed your order to make sure everything went smoothly on our end. Your order was placed on 10/20 and delivered on 11/01. Processing took a little longer than usual, but the delay was minimal - and the order arrived without any reported issues.
If you ever need lead times before placing an order, we’re always happy to provide them.
Regarding your comment about ordering directly from the manufacturer: Mod in Japan has always operated as a distributor for hundreds of brands. We’ve never hidden that, and it’s how we’re able to offer authentic products, competitive pricing, and a wide catalog across many manufacturers all from one place.
As a small business, we work hard to balance speed with the best pricing possible.
If you have any questions about availability, lead times, or shipping options, we’re here to help.
It did not have any fittings in the box now I have to try and find the correct ones and sizes

Hi Charlie, thanks for bringing this to our attention. We’re sorry to hear your kit arrived without the fittings you expected. The Nitrous System you ordered is designed to come as a complete kit from the manufacturer, and missing components are uncommon. It sounds like there may have been a packing oversight on their end, but we’re happy to help get this resolved quickly.
Please email our team at [email protected] so we can figure out how to make this right for you. Thank you and we hope you give us another chance!
Product priced great. Extremely fast shipping and great communication. Will definitely be giving them my business again.

Ordering was easy and package delivered on date stated when I ordered it. Item included everything as advertised. I got free shipping and they had the lowest price for the Air Intake that I ordered on the internet.

Great prices with super fast shipping
The best price around and the fastest shipping I’ve experienced from any company. I haven’t installed yet, but after a full inspection, I see nothing wrong. It looks like a well packaged and well received product.

Awaiting to resolve poor product delivery, quality control concerns with Mod in Japan and Invidia. Weeks have gone by with no solution to date. We have a very disappointed customer as well. Being a small shop in PA this is unacceptable. We have lost time and money due to this mess. The money offered from Mod does not quantify for hours lost and a long term customer's loyalty. Invidia's promise is to provide a high quality product. This was missed due to Mod being a middle man in the products supply and delivery. If you, as a customer are seeking a strong customer service based company, seek another company.

We’re truly sorry for your experience. We are a small, privately owned business and not Invidia itself, but we take full responsibility for supporting our customers when issues arise. In this case, we exchanged the exhaust system once, covering the cost of shipping ourselves, in the hope of finding a better one and making things right.
We also relayed your feedback directly to Invidia regarding your concerns with the final polishing of the exhaust tubing. While Invidia is a value-priced manufacturer, and sometimes their finishing details may not align with every customer’s expectations, that should never come at the expense of your satisfaction.
After reviewing the situation, Invidia offered either an additional discount or a full refund. This decision was made because, based on the quality of the product, it was clear you would likely remain disappointed no matter how many times the system was exchanged. We felt this was the most honest and fair resolution to present.
As a small, privately owned shop, we care deeply about our customers and their trust. We regret the time and money lost in this process and will continue to advocate on behalf of our customers to our suppliers to help prevent situations like this in the future.
I was a little surprised to be honest. The shipping and communication was painless and fast. My exhaust system was exactly as shown. I definitely recommend buying from mod in Japan.

Thank you so much for your kind words and recommendation! We’re thrilled to hear that your exhaust system arrived exactly as expected and that the shipping and communication process was smooth. As a small, privately owned business, feedback like this means the world to us. We truly appreciate your support and look forward to serving you again in the future!
Easy to deal with answered message extremely fast. Item shipped the next day. Wouldn’t hesitate to do business with them.
