Great system, very easy installation and great sound. I've done a lot of research on the systems for my 2009 Challenger SRT and while there are a few louder ones, this system sounds very clean. It's quite noisy on the outside of the car, but at the same time it doesn't bother inside, especially on long drives. This system doesn't have a drone like some others and Amazon offered one for the lowest price I could find. The tips are almost standard in appearance, allowing you to maintain the overall look with improved sound performance. Excellent quality with stainless steel construction and Corsa guarantee. I had to send two such systems, in the first batch I did not receive silencers. Revain sent me a replacement and return label for a partial shipment very quickly.
