It happened last night after work. I was out in the oarking lot outside of work talking with one of my co-workers(good friend). We were BS'ing and I said "let me smoke em alittle before we leave" I convincingly agreed and i proceeded to light them up. After a few of them, I did my last one with my friend facing the rear of my car and I took off at 3400 rpm and quick shifted into 2nd at 5600rpm and a loud pop came out from my exhaust as I hit second. I came back around to where my friend was standing and all I see is my friend smiling, he said I shot fire balls form my exhaust when I hit second. I couldnt believe what he was telling me! I was so excited! This also happened last week when i took my friend for his first real rid in my cobra. He was scared shitless, you should have seen him looking for some where to hold on but we dont have anything to hold on to! I heard the same popping sound then. I sound great! Let me know what you guys think.
