I tried installing these myself but after many attempts I decided to bring them to an exhaust shop. They had to make some modifications before they would fit right. The sound is loud but gets better as the RPM's go up. also, the tips stick out a little more than I would prefer. Overall, they look good (Stainless steel) and sound awesome. The price is right, as well!!! I give them 4 out of 5 stars.
