Looking to construct a swappable cat/straight pipe setup for my car and need the highest flowing cat possible. My turbo puts enough back pressure on the system, so I need something that will flow huge air, but still perform come catalytic converter functions. Any suggestions?

 

I always heard the Random Tech cats are some of the best flowing, smallest cats out there.

Although I do hear if you have an import, siamese or persian cats flow the best.

carsound, flows the best.

 

why? no emissions in fl....

 

have heard good things about the random technology.....why not just run a test pipe though?

 

+1 on the civic

but on my maxima i do have a Randon cat on it, works well.

 

rip out the cats.. why bother.
