I have been reading through the forum and cant find anything on this.Only catbak systems that dont really do anything for performance or am I not understanding right?

I would like to do an exhaust that will be more benefical than just sound,anyone done this.

You read the Notes right?

"Notes
Because your SuperMAXX Exhaust System includes replacement performance catalytic converters, it is not street legal and is intended for off-road and racing vehicles."

106% better flow because the catalytic converters are basically hollow shells?

If you have emission testing where you live you may not want to make such an investment.

 

Have you thought about just replacing your muffler and y pipe? Then with the money you saved not buying a cat back you could put towards headers.

 

In sask. they do not test emissions,I am more concerned with getting codes or light.
