ok i know it is illegal, yes, but does removing the cats actually make a decrease in fuel economy? im wanting the best possible exhaust system i can get with the best performance, thats why i wtill need an X and some headers, which i still cant decide shorty or long tube? its a 4x4 so i dont know.
Long tube headers are the only way to go. Dynatech stainless steel headers are the best you can buy... Id cut all 4 cats off and install 1 high flow magnaflow cat on each side, then the x pipe and mufflers, that is what i have, and its about the best setup in my opinion. I have about $1500 in my exhaust system...
ill admit as good as that sounds, being 16 i dont have 1500 to spend on it...and im saving for a procharger in 2007. It also seems like i read somewhere that edelbrock shorties can add up to, i believe it said, 28 horsepower?
no thats just a lie... I had gibson shorties, all shorties are the same, I gained no hp and no torque, i took those off and put on dynatech long tubes, i gained 30 hp and 35ftlbs torque. If you dont want long tubes, save the money for the supercharger.
