Haven't seen these pipes before. How do they sound. What does the J do
They sound awesome.
The J-pipe is a Helmholtz Chamber, it works a bit like an echo chamber that is tuned to the right length to send the sound wave back on itself and eliminate exhaust drone without affecting the tone.
Not sure of all the science but it works, my has almost no drone (except a little towing heavy at low revs and accelerating or going up hill).
Some info here: J-Pipes and Helmholtz Chambers - PCW - Performance Car Web
They are big in the US where they put them on the G8's
