STP Please help: Muffler Installation

My car sound like an airplane and I suspect it is the muffler. Any idea?

Is it difficult for me to replace the muffler by myself? I do not have welding equipment. Some people say welding is not required. How long normally does it take to do the job? What pitfall can you think of before I started a mess.

管道或者muffler都有检查, DIY换管道很难, 但muffler -stp- 给 stp 发送悄悄话 (135 bytes) () 04/20/2006 postreply 08:45:26

Thank you! So I should wish it is the muffler rather than the pi -色大胆小- 给 色大胆小 发送悄悄话 (69 bytes) () 04/20/2006 postreply 09:07:02
