Hi everyone.
I put the loud magnaflow cat-back system on my 09 g8 gt and i have a popping noise when i let off the throttle in the active select mode. When the engine is holding back it pops a few times when i downshift. I was just wondering if this is normal for this system or if I might have a small leak? I like to drive in active select mode so it stays in v-8 mode, sounds better
.
This is the first car i've had that I had to use the cruise control to keep from speeding.Awesome!!!!!!!
