rattle at 1000 rpm's
 

Whether the car is hot or cold, as I'm in 1st gear, slowly accelarting after the clutch has been let out, as soon as the tach hits 1000 rpm's it sounds like the exhaust is going to rattle off the car..

I have the Apexi WS 2 exhaust, has anyone else had this happen?

I'm going to use my shop's lift on sat to see if everything is tight, but I really don't think this is due to a loose bolt etc...

Anyone else experience this with an aftermarket exhaust?

I have the same problem. Though I traded one rattle for another.(FIxed one, got another). My problem is sort of evident though. I have the Borla Dual system along with cat deletes and DC Sport headers. The multi piece Borla system has way to many variables. So its hard to correct, but the Apexi is all flanged. Maybe the system is bent or the shop that installed it made an oops! along the way. I am getting mine fixed tomorrow.
