2018 Jeep Grand Cherokee Trackhawk
Installed shorty after I purchased in April 2019, didn't like the way it sounded. Had several conversations with Tech support @ MagnFlow about the terrible raspy, blubbering sound it made, thinking it was making contact somewhere. Made me think it was a pop off valve or blow off valve releasing. Put original exhaust on & off several times. every time OEM exhaust was installed no strange sounds. It only made these sounds under full throttle and I thought OEM sounded better, Tech said give it a few hundred miles. MagnaFlow even offered to take it back, but I had already gotten rid of shipping box & packing material, so I didn't want to go thru the hassle of trying to ship it back. Just wanted some feed back if anyone has had this situation, kind like nobody's ever heard of this, talking to Tech or Service writers, make me crazy why I'm the only one.
