Converting to Dual Exhaust

[GodStang]

True dual on a mustang is any exhaust system that has 2 pipes all the way back. It can have no cats (off-road) or a million cats if you can fit them. They can cross into an x or an H or go stright back and never come together. The X-pipe and H-pipe help equalize pressure therefore creating more HP.

Fake would be a Y-pipe. It comes off each headers or exhasut manifold and goes into to one pipe all the way back to one out-let. Some people take the one muffler and when it comes out it branches into 2 tailpipes. That is fake. Some are one pipe all the way back and than spilt to 2 mufflers and 2 tail pipes. This is also fack.

In another words if each header/exhast manifold has its own pipe and muffler all the way back it is true duals even if it has Cats. If it is ever just one pipe no matter how many exits it is fake.

Hope this helps.
