Eh. The kid is 16 give him a break. When I was that old I had a 4cylinder mustang and I used to do burnouts in. When you get your first car you usually think it's cool. Then after you blow it up or run into a tree on a dirt road you learn that that was maybe not a good idea treating your baby like shit.
There is no way you have all that and are still that slow. I just got rid of my 99 3.8 and it would run all over that. pacesetter headers, 2.5 all the way back. si/do. FRA mod.
If your car runs like that w/ those mods you need to see a mechanic or something.
My car would run over lightly modfied 5.0's all day. From your video you couldn't run over a honda with a banana stuck in it's exhaust.
