Unfortunately my state requires emissions testing (both visual and ODB scanning). I'm looking for a good high-flow cat to put in my mid-pipe. I'd love for it to not rob more than a few HP so if any of you have any recommendations, that'd be awesome. I'm pretty sure most of you will say Random Tech. I'd agree, however I currently have a 2.5" setup and probably will be upgrading to a 3" setup within the next year, just don't have the cash for one right now. I don't want to drop $2-300 on a Random Tech if I don't have to as that cuts into my 3" plans.

 

1 rubber mallet + 1 long screw driver = high flow cat

 

for smog testing why would you go high flow? keep it catless and use stock mid pipe for testing. california now sells c.a.r.b. # cats, another way to tax us again

 

i was looking at vibrant performance... 130 bucks!

 

check out magnaflow I had it with no issues...
