    Not too long ago I saw a guy post a pic/video of his car and his exhaust stopped at the end of his down pipe. I understand this won't evacuate fumes to the rear but is it an option? I don't think it'd effect the turbo engines function but I'd like a confirmation. Even pros and cons. Just thinking in a public forum.

    Option for what?

    It'd be annoyingly loud.

    How's that?

    I've never tried it, trying to figure why he did. And I was asking if it would effect it as I could not see any affect in theory.

    Thanks

    Lol! Wow, that took a turn I wasn't expecting.

    So it's loud, but annoyingly loud like when I had to drive home with just headers installed and no exhaust! Loud enough I was surprised the two cops I passed didn't pull me over.

    Buy an electric cutout. It helps the turbo spool a lot faster. I have to use two tunes though. One for open and one closed because my car goes lean at Wot if I open it without changing the tune. I only open mine at the track because it is loud as hell.

    ^ this. My car spooled a tad bit faster with the cutout open (PT-61). Before the trans took a dump on mine I left it open all the time and never had an issue with LE. Granted, I also didn't drive the piss out of my car on a daily basis and loved the way it sounded. Highway speeds the drone can get annoying though. With that in mind a cutout solves this problem because it can be capped when you don't wont the loud exhaust.
