urs1ne Posted September 9, 2008 Share Posted September 9, 2008 If I want to go stage 2 with my Cobb AP do I have to use the Cobb downpipe or can I use my Perrin catless downpipe I already have sitting in my garage? ^ n00bs below this line Link to comment Share on other sites More sharing options...

urs1ne Posted September 9, 2008 Author Share Posted September 9, 2008 So any downpipe will work for the Stage2 map? I take it the real difference is when you get it custom tuned because it can take advantage of a better flowing downpipe? ^ n00bs below this line Link to comment Share on other sites More sharing options...
