i was trying to decided on getting one... with my greddy evo
what do u guys think?
i think the brand i looked at was catco
does it effect the volume of the exhaust?
thanks

 

i personally dont think it's really necessary.

Just get a y-pipe and a straight(race) pipe.

 

Depends on how stringent the vehicle inspections are in that area...

 

good point......

 

Don't even bother with the straight pipe unless you are doing forced induction.

 

so u theres no inspections ive ever know of ...
so would it be good? (power wise)

 

Ive done a lot of research on the 2K2 Cat... the only improvement will come if you use a straight pipe. No aftermarket cat wil help. It is a good free flowing cat , that sits in your car right now. I know with a 2K- 2K1 it's different....You will get a gain there..

 

Nope..same thing..why would be different? Actually, cars these days which come with modern 3-ways catalyst are pretty damn efficient...that You will not feel any noticeable difference by changing to high flow Cat (unless you got super sensative butt, then I can't help you).

If you got no Force induction, exhaust work can't really help you that much...besides changing Y-pipes in our cars.

BTW, Warpspeed's metallic Cat could be a different story..waiting for some feebacks...

 

no.

 

I second that no.

 

third i know 2 that gained 0 whp on the dyno with the RT cat

 

The stock cats are already good and flow pretty freely.. When I swapped out with the RT I didn't notice a difference in my butt dyno.
