Repackable back box

  1. #1
    Is there anywhere that will supply a repackable back box for a vtr?

    Wanting to do a few track days with my r, but with a 421, and straight through ss centre and some random bb I think it will be too loud for most tracks.

    Failing that, what back boxes are there that are pretty quiet?

    My VTR with a Raceland 421, SS Center pipe and Magnex Backbox made 72dB last at Oulton Park. To go over the limit you need to be pretty loud tbh.

    Gonna have to try that then, my last vtr, full ss exhaust - 421 mani, straight through to ss back box - hit 102db at Cadwel, had a piper 270 cam tho.
    Tho i have a piper 285 and rallye inlet to go on this one, so am a little bit nervous
