Dammit, I need to get a cut-off wheel and MIG setup down here...
If you can wait a few weeks, I can make you an exhause system, but I need to buy the afforementioned items first!
BTW - I tried to take some pics of the 1JZ 240, but the day was dark and the picture came out looking like someone had laud down a washboard in the engine bay.
Just imagine a 1JZ, then imagine a nissan 240, and put them together
