Default Knock after clutch/header install

I just went from a stock clutch/pp/fw to a TEX OZ-700 and SLP LT's to KOOKS LT's. ONLY when I go from a stop and pull off in first, I hear a knocking from, it seems to be, the clutch area. It sounds more like something hitting something else than just a popping/knocking though. I torqued all bolts to spec so i'm not sure what to make of it.....Ideas?

After I installed my headers, they smacked the floor board on the drivers side. I had to make some room for movement with my air hammer.

I went from SLP lt's to Kooks lt's strictly for the clearance, i've probaby got another 2 solid inches of clearance with the kooks. I mean they fit SOOOO good and tight underneath so Sepsis, you may be right. However, I remember telling the gus helping me with this that the Kooks y-pipe didn't fit very well to the exhaust bracket so that's another thing i've gotta check. Motor mounts would be my next mod I reckon since i've got such a large cam.... Thanks for the response guys.....

MM98, there's no way this noise i'm hearing is any kind of chatter....I'm sure we torqued every bolt to specs and it's a Tex OZ-700 which isn't supposed to come with any chatter. Thanks though.

I thought that since the y-pipe didn't fit the exhaust bracket so good (it's offset to the right) that that would be the problem, but I put a rubber pad between the two and I still got the knock so i've gotta rule out the exhaust bracket knock (although i've considered the option that I put the bracket back on backwards). The kooks fit SO well that i'm betting it's hitting something but I haven't track it down yet.

My drivers side of the Y was hitting, not passenger side.

I installed poly mounts with my headers. My header collectors are 3 1/2 inches. Most are 3" that's why I think it was hitting the floor.
