Are Headers Do-Able For Street This Way?

[Homeboy981]

Hey @JD,

This IS DEFINITELY not a "short cut", more like several difficult cuts, followed by welds and such.

I already have Cat Deletes, so my secondary cats are gone!

But having a better "outflow" design, in other words, longer tubes for EACH of the cylinders helps, doesn't it?

Don't longer tubes ALWAYS solve most problems, particularly from the exhaust? Kidding about that but VERY SERIOUS about trying this. If it is worthy. Know anyone who has done it?

Thanks!
Mark

Keep in mind, the secondary cats are just as restrictive (and maybe more if they' share the same part as a 996) as the primary cats. With that said, there's really nothing to be gained as far as performance is concerned. As I've said numerous times in the past, there's no short cut or inexpensive way to improve upon the oem exhaust system .
