What is the best way to make my 2004 v6 mustang sound like a growling beast? What modifications do i have to make and what do i have to purchase? Please help me out.
Mac Longtube headers, mac h-pipe; no cat's if you don't have emissions testing, cats if you do, magnaflow stainless magnapack catback system, and a mil eliminator if you have no cats. Your car will sound like a beast. Make sure you get the magnapack though, cause thats what will be the nicest and loudest. The Magnaflow system is $330 if you buy it from partshopper here on the site, and put in the coupon code, the mil eliminator is $30 if you can solder, the headers are $230, and the h-pipe is $150 without cats.
