Well, I recently installed a Kamikaze header, and it hooked with my Catback Exhaust, but ever since, whenever I accelerate, and hit about 4000 RPM's, I hear a weird noise, kind of like something is rattling, and I can't figure what it could be, this is my set up right here:

I'm having a problem with this last shot also, the exhaust hangar keeps allowing the exhaust to slip out, which causes it to keep hittin my bumper, so, if anyone can help, I will greatly appreciate it

 

is it a rattle or is it more of a buzz? if it's a buzz that's just since the exhaust pitch was changed when you removed the first cat.

otherwise it could be the kamikaze downpipe hitting the underside of a crossmember near the oil pan... the stock downpipe is crushed so it doesn't make contact there.

 

well, it is more a buzz, not really rattle. It sounds like the old school idea of putting the baseball cards in the wheels of ur bicycles spokes, ya know what I mean? Is there any way to fix it?
