VRRacing Posted March 2, 2015 Share Posted March 2, 2015 So my JDM 350z soon to be race car has a cobra exhaust on it. No idea if it's any good performance wise but it sounds decent. One cat appears to have started to crack on the weld and the other cat looks like a pigeon took a s$€t on it, also on the weld. So must have gone previous. Any way besides the point. I'm going to make up a few exhausts along with removable cats and see which performs the best. Anyone tested the various options? Ive been told 2 all the way gives the most power. We shall see. Will hopefully get done over the next few weeks. Pics to follow. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
KyleR Posted March 2, 2015 Share Posted March 2, 2015 (edited) I think true dual with an X or H pipe for scavaging makes the best power. Edited March 2, 2015 by KyleR Quote Link to comment Share on other sites More sharing options...
