I just ordered the SLP loudmouth catback for the Black Beauty. These will start shipping next week. For those of you unfamiliar with SLP they were big into performance mods on F bodys (Camaros etc) They then branched out to the Mustang crowd and now the MOPAR offerings. It is true bolt on system, well engineered and sounds AWESOME! here is a vid of SRT 8 with loudmouth and headers to give you the idea. Oh yeah the part number for R/T 5.7 is D31017 Enjoy Oh yes free shipping this week also and much cheaper in price than other systems i've seen! Rock on!
