Very easy install and excellent sound.
I had bought these UEL headers and there was some issues in shipping, took a little while to receive. But once I got them, they came just as expected. The tail end of the system didn't exactly line up perfect with my Spec-D cat back system. But that's to be expected I'd say, I made it work and awaiting having them welded together. SEMotors was very transparent the whole time and kept in contact. Would recommend, took about 3 hours to install, including jacking the car up. And with the Spec-D catback eith high flow resonator, it's quite loud but not too droney. Love it.
