Ironically I bought an invidia q300 while I was waiting for my nameless to be built (nameless performance builds to order) I had to hear it for myself the diff between the two. IMO the nameless sounds way better then the q300. Not to mention the quality between the two. Nameless quality is the best. Made in the USA. USA steel. Invidia you need ext hangers so you don't burn your bumper. Here's a link to my set up. It's everything I have on my car now.
Some people have burnt there bumpers. Not saying everyone. When my q300 was installed, it def sat close to the bumper. If it didnt burn, I'm just passing on some comments that I heard. Keep an eye on it
