I know that there are plenty of forums for exhaust mods, but I was just wondering that when the stock exhaust gets mod, does the weight change at all. Supposedly the Jardine Exhaust is alot lighter than the stock. Any advise, I do plan on sending my exhaust to Hawk since thats the one that most people say do the best job with performance and sound. I was wondering if there are any forums for intake mod. I saw a firebolt with a cone K&N coming out the side and that looked cool as sh*t. Wonder if that helps with performance?
