Let me start by saying "Great Sound" I didnt want that mustang backyard chop and weld sound I also didnt want my car sounding like a ram pickup.The sound that you get from the pypes axleback setup sounds expensive and exotic I like it at higher rpms on the highway.Easy installation.No complaints.when you add to a car with a cold air intake it sounds sooooo good.This product has that euro sound not jap not redneck more like those jags (on sport mode)impressed with value for the price

First catback I've ever installed but was very easy with the clear instructions. Definitely recommend having a friend or two to help. Especially while getting everything aligned. Sounds awesome, slightly quieter inside at cruise. Nice and aggressive without being obnoxious at WOT. Expensive but, you get what you pay for.
