今天帮C30换了ASPEC的双出排气中尾段，总结一下，声音方面低沉有力，ASPEC的声音确实是给力，烧蓝尾喉

                                                                 原车的排气，尾喉挺小的

                                                                        ASPEC

                                                                         烧蓝

                                                                       开始安装中段

                                                                     尾端安装

                                 ASPEC烧蓝霸气的尾喉，比原车的尾喉大了好些，相对大气很多

C30油耗多少？
