I just removed the resonator my 06 L6 TB. However, I did it the more expensive way. I bought the spectre performance piping. I will upload a pic in a day or so. Well it works like a mother!!! The TB rocks on the top in!!! Not only that I am looking to buy HPTurners just to try to eek out what I can from it. After reading the thread,"So this is how our throttle body works?", I can see why these trucks have so many issues.
May be GM knew that the L6 was a kick * motor but had to chop it's legs off to make the average Joe happy. Well too bad they don't sell an intake manifold with two or three throttle bodies and some large as heck injectors..... I would make feel like I was back in my old 260Z!!!
