Test Pipes Vs High Flow X-pipe???
So i was thinking the other day about what would be a good pair for the M performance exhaust. i used to have the Acm test pipes before, but now i am OEM. i sold the test pipes because i wanted a lighter unite and similar power. So i was thinking about the ActiveAutowerks High Flow Cats x-pipe.
which do you think will create a deeper tone: ActiveAutowerks High Flow cats no secondary & resonators. or Acm test pipes/stock oem x-pipe? |
