.As for the center mount exhaust, in my opinion it sounds DEEPER and MEANER on LT1 than it's on an LS1, but I guess that's a matter of opinion. I heard it once on LT1 and a GMMG exhaust, it sounds sick, so freaking mean.
unless I'm wrong about the reason why it's noisy and you can help, I replaced it around 3 months ago but it was noisy at high rpm most of the time, what could cause that.
