downpipes vs stock video

hello, i wanted to see a video of two identical cars but one with stock downpipes and one with aftermarket catless downpipes but i cant seem to find one. all the videos are of completely different modded cars so its impossible to compare how much just adding dp's adds. does anyone have a video of this? thanks


EDIT: i am looking for a drag race video, sorry that was not more clear

Simple Youtube search did the trick:

Stock exhaust:



AR downpipes with stock exhaust:



I ran downpipes with a stock exhaust for over a year. Cliff notes are: It's slightly louder and more aggressive but remains true to the original sound. No drone, at all, just a slightly beefed up 'stock' sound.

yes the above clips should be fine. I mean the other 'mods' on a car don't matter, unless of course they have other exhaust mods like muffler/resonator delete etc. The vids put up are both N54 coupes so you're good (E90 exhaust setup is slightly different and of course N55 wouldn't be a direct comparo)

I ran this set up also for a long time and it is a nice, tame upgrade in sound. I just recently decided I wanted to up the ante a bit and went for catless DP plus BMW perf. exhaust. holy monkeyballs, it is pretty aggressive and sounds like a racecar, popping and gurgling as much as my dad's C6 grand sport.
