Well a mechnaic told me my cat was bad, and has been for some time. I took it to someone eles and the verified it and said the same thing. SO i guess i am going to replce it. but can a cat effect performance to a noticeable extent?

So since it is bad i decided to get a hi-flow cat since i have to buy one anyways. I hear dthey really make no differance, but do they make any at all?
also are there any legal hi-flow cats that will pass emissions? I just do not want to mess around with having to take it off and ****.

 

as far as bad cat....if its all clogged up it can hurt performace....hi-flow legal cats...i dunno....where i live if not CEL is on and u have a cat....ITS LEGAL to the inspectors...but thats in buffalo

 

my mechanic told me that high-flows would pass emissions fairly easily, and thats in cali, so we got high standard. i think itll all work out.

 

warpseed has a legal high flo cat converter, tell em ur a .org member and u ll get it for like 85 shipped, and a y pipe for a buck 60

 

i got me a warpspeed y-pipe.......now i need a new flex for it....and i guess tjeir cat.....would any gains be had off of this cat at all. i am not buying it for the gains, but since i need a new one why not get a hi-flow if i can find a legal one.

 

Federal law states that as long as the car has 50K miles on the odometer, virtually any 3-way aftermarket converter may be installed, so long as the car can pass applicable emissions tests.

 

I clogged cat or one that has broken apart can kill your power. If it is has broken apart it depends on how it has wedged its self in the B-pipe but we had a car in our shop once with a bad cat and the car could barly make it up a hill it was clogged so bad.
