<p>The exhaust pipe tailpipe trim (2) has a trumpet shape with an initial section (A2) of a small diameter (D) with a following end section (A3) of a larger diameter (D1). When the exhaust pipe is cold, the tailpipe has a gap space (S1) to the round neck (3), which is smaller than the temporary changing gap space (S2) between the tailpipe and the neck when the exhaust is hot and the exhaust pipe expands longitudinally.</p> |
