The perfect mate for my SW headers, this system replaced my old stock dual system with flowmaster 10 series mufflers and OEM baffled Marauder tips. My brother has a 02 GT Mustang and he says it sounds better than his car, which has a BBK off road H pipe and flowmaster 40 exhaust. This big boat sounds MEAN now and turns heads when running WOT, people dont expect to see a full size luxury car barreling down the road haha.

An excellent choice, I’m glad Chris talked me out of the Borla system, this setup sounds incredible!! Bought this with the long tube catted headers and man oh man is it nice!! Car sounds angry and idle and an outright demonic monster at wide open throttle. As always Chris was the man when it came to deciding which exhaust to go with. Thought about having the Marauder tips cut off and turn downs put on, but it kinda grew on me! Want an exhaust, go with these!

Bought this during ADTR’s 2018 Black Friday sale for my ‘04 CrownVic after I had already installed ADTR’s front & rear sway bar kits. I bought SW’s chambered exhaust system. My car now feels alive and feels like it really wants to go! And the sound is addictive—it’s hard to resist putting your foot down!
