Well I was coming back from Wendy's tonight on my way to work, I was going around a turn from a red light and I wanted to kick out the tail a little which I did with no problem, just having fun. When I noticed a problem I've been having ever since I got the truck, I didn't want to let off the gas............lol. Make a long story short I was hammering on it all the way until about 70 when I hear a VERY deep rumbling coming from drivers floorboard. It's extremely loud inside the cab of the truck now but outside nothing sounds or seems to be loose. To be honest it sounds like I have headers on the damn thing but I don't yet :shrug: . Oh well I'm taking it to get looked at tomorrow morning, the good news is I think this will give me a way to justify getting some headers. Looking at the Bassani's but they are awful expensive and their website sucks they don't have any sound bytes of stuff installed on the truck at least that i've seen. I think I may have just blown a Cat or possibly a seal at the exhaust manifold though. No check engine light though so I'm not sure. Anyone have any suggestions on what kind of headers have that "I'm gonna eat your leg off" sound, and some sites to buy them from?
