    S13 exhaust recommendations

    Currently have an apexi n1 which is 3.5" from cat back and loud.

    Was 99db @ 4k tested at Bedford so fitted a silenced decat and tested yesterday at 96db @4k.

    It's not so much a problem regarding track but it's a headache on a long journey.

    Can't run with a bung because it restricts the hell out of it.


    So want something quieter but not restrictive, any recommendations?

    Contemplating removing the silenced decat and getting a better silencer welded in.

    How about one of those butterfly valves instead of a bung

    I did try one years ago but was only a cheapo one from ebay, I think I want it quieter all the time mind.

    I would personally get a better silencer welded in (I too have an apexi n1 with a silenced decat and find it perfectly manageable).

    It's fine for short journeys but travelling 2+ hrs to shows it drones on a bit, thinking il remove the silenced decat and get a long silencer welded in
