I did a search and did not find a thread on this. I am thinking about having a custom 3" exhaust fabbed up for my car. My question is, should I go with an X pipe or an H pipe or even a true dual set up? I have read that the X pipe will be a little quieter than the H. I have also seen Mustang dyno charts that showed a loss of low end hp and tq with the X pipe, but a higher top end hp and tq. I think a proper X pipe helps with scavenging at higher rpm thus the increase. I looked at some pictures of bolt up systems. Flowmaster seems to use an H. I think the Corsa was close to an X design which may be what eliminates drone. What do you guys think?
