Im planning to get an rmf header so I also need a 2.5 high flow cat to properly connect the two. I know 5th gen preludes are really sensitive to aftermarket cats and randomly spring check engine lights on the cheap ones. Do you guys recommend any aftermarket cats on 5th gens that won't spring a check engine light?

 

Try Random Technologies.

 

threads like this make me feel bad for running w/o one.....actually na cause i just remembered its like 8 times cheaper than a cat

I second this.. I have a Random Tech Hi Flo on mine... I like it. Passed emissions no problem and I have not thrown any codes since installing it.

 

carsound works well, make sure you get one with a bung welded in for the o2 sensor.
