What do you want the engine to get better in. Horsepower, torque, fuel mileage, reliablity, getting it back to proper running?

How much you willing to spend.

Since you dont know if you have emission tests then you dont have it.

For your own descression this is illegal to drive a vehicle modded exhaust on the federal or state roads. So do this at your own risk.

And removing the catalytic convertors if found out is a hefty fine.

But that out of the way any exhaust system that you like that you can buy online will fit in your c ar if it is made for it.

May require some minor mods. From experience best way is to have a shop make you a custom exhaust
