The Tsudo exhaust seems to be of decent quality but the massive drone will give you a splitting headache while driving. I bought one due to the other good reviews but during any type of acceleration or deceleration the drone is almost intolerable. While cruising it isn’t so bad but in the city you will be regretting having this. It honestly makes me not want to drive the car. I will be driving it with the silencer until I can change the system entirely. I don’t know how other people with this system are able to stand the interior resonance but I’m impressed with their ability. I’ve had 3 other cars with modified exhausts and never once experienced anything like this. I was really excited to buy this but man it’s disappointing
The problem is that sound is subjective so a good purchase is hard to base it on reviews. Even listening to sound clip, it's done in such an uncontrolled method that it's hard to capture accurately, not to mention, exterior vs interior sound is completely different. Other factors like stock DP, hi-flow, no cat, will alter sound and drone. A lot of mods are opinions and should be taken as anecdotal evidence at best. People who drive at different rpm will also experience different sound throughout their commute.
I'm personally using COBB, but it is more on the tamer side. It doesn't make everyone at the parking lot turn and look when I start the car up, it almost sounds stock tbh. It gets louder when you actually get on boost, but not when you're just cruising. It's sort of like a "trigger" mode where it only gets loud when you're actually going, not just "always loud, and louder" whether you're rolling in a parking lot or actually on boost. There's no drone, that's what I personally like. But I understand it's also too quiet for majority of people, especially if you want people to be turning their heads to hear you before they see you.
