TOG (The Other Guys) or Arizona Speed. Get them Jet-Hot coated in and out too. Screw that ceramic coated crap. Shorties arent worth the money or the time it takes to install them. Im going to speak in regards to the LS1 based motor in NBS GM trucks. JBA makes the best shorties for the 4.8 and 5.3. I dont think I have ever seen a set of shorties net over 8rwhp other than the JBA's. Long tubes will get you the HP!! Well worth the cash!!
