I recently went to the 4" turbo back exhaust, with a straight through muffler and it sounds really nice. However, now when idling I get this sound like someone put a cap over the exhaust for a few seconds and then it is back to normal. Any ideas? I am sure the changeover probably had nothing to do with it but just made it easier to hear.

It's kinda funny how many of us think "What did I do to create that sound?" when we switch to turbo back exhaust. Once you guys told me it was normal it sounded pretty good to me!!!!!!!!
