For a complete new exhaust system, tail pipes catalytic converter and muffler it could run $1200 - $1800 depending on make and model.

$300

Depends on the vehicle. Can be hundreds (for a domestic) or thousands (for an exotic or luxury).

As much as it is for your specific car, every car is different. You also need to decide if you want mild steel or stainless, standard or performance, good quality or budget....

Hi so that depends on what make and model it is so be prepared for a shock.
