exhaust question
I just installed MBRP cool duals.It 's a nice system.My question is when I start my truck it has this real nice rumble ,then it's like something closes and my truck get real quiet.When you stand at the back by the tail pipes you can hear a high pitch coming from the turbo but it seems like nothing is coming out of the exhaust.I presume this is normal and just wanted to be sure.Is this because of the varible vein turbo ?
When I did the exhaust on my 7.3 it was loud even at idle,so it just kind of surprised me at idle that it's quiet,once I get on the road you can hear that rumble.I just wanted to check to see if this is normal ?
Thanks
