I. Reading Exercises:
Exercise 1. Read and memorize using a dictionary:
adjust; bend; exhaust; flexing; molded; muffler; remove; sheet; stainless; tunable; |
Exercise 2. Answer the questions:
What are most premium-quality performance mufflers and pipes made of today?
How are performance pipes formed?
What is the main drawback of one-size-fits-all mufflers?
What happens when the stock muffler is removed?
How can you change the sound quality?
Exercise 3. Match the left part with the right:

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.
