Not sure which 2004 Ford Crown Victoria Performance Exhaust Systems are right for you? We have over 7601 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"This exhaust is great, I have noticed a small increase in HP and it is louder than stock but not very loud at all. The exhaust is very quiet until the pipes warm up and then it gets a little louder, but it is not unbearable. Installation was easy once the stock system was removed; however, the new pipes were not supplied with the bolts to attach the flanges together after the cats. The exhaust looks great and bolts right in. The price from Autoanything was about $100 cheaper than other sites." —Theodore A from Russiaville, IN bought a Borla Exhaust Systems for a 2004 Ford Crown Victoria.
