On March 4th, I decided to blow some bonus money and splurge on a TCR muffler for my GTI. When ordering, the website gave me the option to add a 55mm exhaust band clamp to the order. I did this specifically because I figured it would surely be the size that I would need to complete the install quickly and easily. I received the clamp right away, and stashed it away while I waited for the muffler to arrive, knowing it would likely take a fair bit of time as the item was to ship from Germany. But after a month, I noted that the muffler had not even shipped so I contacted customer service to see if I could just get some idea of when the muffler might at least ship. I was told that the item would likely not ship for another 2 to 3 months. See, the thing about impulse buys is that sellers need to get them into the hands of the customer quickly, so they don't have time to rethink their purchase. Waiting a month gave me plenty of time to think of all the other things I could be buying with $700+ instead of a muffler. So, I opted to cancel the order. At that time, I decided to just keep the 55mm clamp thinking that I'd likely order something else someday in the future. And I've continued shopping for exhausts, and while I haven't found anything, what I have learned is that the 55mm clamp that I ordered with the TCR muffler is actually too small for a 2018 VW GTI, so even if I DO order something else in the future, I'll also need to order the correct 65mm clamp. Based on this entire experience, I'd likely rate Urotuning lower than 3 stars excapt that, at the very least, customer service was very good. They responded to may emails quickly, and did not give me any trouble cancelling my order. Thank you for your help again, Kelsey! Eurotuning, go ahead and put that TCR muffler in the container coming from Germany and reach out to me. Maybe I'll make that purchase anway.
