Magnaflow Quality?

[TJay74]

I have used the 12909 on both of my 6.2 trucks with no issues at all.

I have been driving with the 12909 now for a little over a week and I am totally satisfied. Like the quiet at cruising, low rumble that sounds like a v8 and not a prius at idle, aggressive sound when giving throttle, and lastly controlling the chopper/drone in v4 without a flapper in place..... HOA/wife approved. Thanks for the feedback.
