Exhaust upgrade

[nag]

I have a 1986 diesel right side drive Townace. I'm looking to replace/upgrade my exhaust. Are there any bolt on ready made options?

What do you mean by "upgrade". The exhaust fitted by Toyota is optimised for the car by the car designer.

This was my initial reaction but, seeing that the car is a 1986 model, it is reasonable to suppose that there could have been subsequent developments to improve emissions,  and there just may be an after market upgrade (not necessarily a Toyota one) that is suitable for this particular car.
