Nasty Sounding Exhaust

Drag0na5h · 03-23-2006, 02:24 AM

Anyone else here have an Apexi World Sport 2? I just put one on my Automatic 87 NA and when I accelerate from a dead stop the exhaust has a deep roar, but as soon as my car gets to 2500-3000 rpms it sounds like metal rattling! As soon as my car is going past 20mph the exhaust is very quiet. It only happens during acceleration. But after I've driven for a while and my engine and exhaust piping is all warmed up...there's no rattling during acceleration. I don't get it??? Any advice would be helpful.
