American Racing Headers 50 State legal Shorties Install
Hey everyone, Let me start out by saying as some of you may remember, I posted previously that I had a ZL1 on order which I had to cancel. Anyway since I canceled the order I got the itch to do some mods to the car I was planning to trade in, my 2012 L99 SS. My first thought was my dealer is really not to keen on mods but will tolerate some as long as it is not too over the top. At this point I only have a cold air intake. I remembered reading that American Racing Headers had developed a shortie header that they claimed to be 50 State Legal and from the looks of it, had some pretty neat features. I did some investigating and found out that they were approved by CARB or ARB. Apparently from what I could decipher the American Racing Headers passed the strict CA emission laws with flying colors.
After talking to Nick, the owner of America Racing Headers, I made an appointment to have the Shorties done. The install was fast and neat. Everything bolted up and cleared nicely. I really liked the ARH wire insulators. They dressed up the engine compartment nicely. As soon as they fired up the car I could tell right away the sound was throatier than the stock exhaust manifolds. The throttle response seemed quicker. At the time I really couldnít get on the car due to heavy rain. On my drive home, about 35 miles, my highway mileage seemed to be about the same as before, around 25.8 mpg.
As I got closer to home I encountered some dry highway roads where I went WOT and I immediately knew it felt stronger than stock. The real test didnít come till this morning where for the first time, with traction control off, it lit the tires from a standing start like never before. And it did multiple times. I didnít dyno the shorties but the gains have to be pretty substantial. Overall Iím impressed with American Racingís shorty headers. It was a mod worth doing, especially since I donít want hassles. Next up, Iím saving for the ARH full catback. I canít wait to get their X-pipe installed and Iíve heard their mufflers on other Gen 5ís. Iíll keep you all updated with sound clips and my experience with the system. Thanks.
