R32 GTR "side pipe"
must stipulate, this is for TRACK USE ONLY!
bolts up to end of the Y merge front pipe, replaces cat and rear pipe with a 2.5" mild steel pipe. Goes to rear cradle, turns and dumps just before the rear wheel
Its loud as buggery, but thats what a side pipe is for
can get some pics
$150 (basically the cost in materials)
