The best!

Tamed at idle and aggressive on throttle without being obnoxious. Sport but still OEM appearance. No exhaust leaks with gaskets provided. Even threw in a shirt! Good job guys 👏🏼

Very nice. Perfect fit and fast shipping. Thanks STM.

Wow, wish I'd have replaced my Tomei sooner! This looks so much more mature, the attention to detail where tip angle/placement is concerned is spot on! This exhaust bolted up with zero issues and it sounds amazing! It is surprisingly much more mellow and subdued when you need it to be compared to the Tomei, all with a single small Vibrant muffler. 10/10.

Compared to my old exhaust it was much quieter even with GSC 3 Cams. I also added a vibrant resonator on, which is perfect for daily driving.
