Te magnaflow inthe vid above sounds like stock but a bit 'farty' and raspy (that's what a res delete does). It also is a terrible cat back because it's only 2.5" piping .. Stock is 2.5 with a small crush, it is BARELY an upgrade (so actually no more, if not less, gains than the bmwpe)
For the same money as either you could get a custom muffler, cat delete, twin 2" from the headers into a 3" or 2.75" (bit quieter) with a res , all stainless and mandrel bent, and mop the floor with both of them -_-
Why people buy these things i don't know
The one reason i am hesitant to follow my own advice is i don't want my car to sound even CLOSE to those videos, it's what's making me contemplate a laptorr seriously
