E63.. dyno video before and after primary cats. 25rwhp gain

[Fonzie Audi]

I got a copy of video from one of my first mods. Who would have thought I'd gain 25hp to the wheels just replacing my primary 600 cell cats with 200 cell. here's the video..

Nice vid Fonzie, is it 200 cell or cat delete. Vid said cat delete:)

Hey snoop!
There are huuge primary stock cats (600 cell) attached to the headers. They were replaced with 200 cell H/F. The secondary cats and resonators were true deletes.

I've spent hours and hours on MB forums to see if anyone else has played with the primary cats and have found nothing. Renntech says they've never replaced the primary. Lots have done secondary and/or resonators.. but i may be one of the first to do primary. Putting together a drive by/acceleration video this weekend.

I'm sorry but what does that have to do with an E63 or Fonzi's girl? For that matter why is this in the RS6 / S6 / S8 thread to begin with?

Fonzie had an RS6 with crazy pipes and exhaust, then a turn of events for him, he had to sell it and then a couple of days later, another huge turn of events...

Whatever Fonz posts wherever he posts it is on-topic in my book.
If that Benz sounded any sicker it would need a penicillin injection system. :applause:
