"This is a great product. Can feel a difference in power and sound. Sounds deeper, I also have a 24" Magnaflow muffler which goes great with these. The only bad thing about them is the installation. I usually like do my own installs but there is NO WAY I could have done these. I took them to my mechanic and he quoted me $250.00. It took two of his guys about 14 hours to get them on. He was upset that he quoted me such a low price.
