scottishforester Posted January 13, 2020 Share Posted January 13, 2020 i have a custom cat back on my forester. have had it just under a year. love the sound, however I'm wanting to downsize the tailpipe. its a 4.5" tail with 2.5" piping. i find it a bit too big, but also dont like that i can see the cone shape reduction on the outside of the pipe. 2 questions. i would like something more functional/rally looking, like group A wrx rally car. (less shiny, more raw looking lol) is it possible to just use exhaust piping as a tail pipe? also it is possible to have a back box that has a 2.5 inlet, with a 3" outlet to avoid a noticeable reduction in the pipe? cheers Quote Link to comment Share on other sites More sharing options...
