| 2. Aluminized steel | b) are made of stainless steel. |
| 3. Performance mufflers are available | c) raises another issue. |
| 4. Making modifications to a stock exhaust system | d) is much better than plain, uncoated or painted steel. |
Exercise 4. Open brackets choosing the right words:
Direct-fit mufflers usually do not require modifications or changes because they are (painted /designed) to replace the stock muffler perfectly. Most are a simple bolt-in installation that connect to existing pipes and have (mounts/tables) that line up with the stock hangers. The major drawback with direct-fit custom mufflers is (limited/free) availability for less popular models.
