So I'm new to this site and I have a question about my lude. I have a 2001 prelude type sh. The engine light popped on and I got it read and it was the catalytic converter. I was thinking of just doing race headers and a flash to delete the cat all together. Any thoughts? Anyone with the parts as well?

 

were not here to tell you what to do to your car. but what you have planned sounds good.

 

you can't just flash the ecu. you'd need to buy a tuneable ecu, then get it professionally tuned. entirely too much money just to eliminate the cat, and it will also make it fail emissions because it will convert the car to obd1 which can not be read with any scanner.

just buy 1 header, because your car only uses 1 single header. it does not use headerS like domestic v8's do which have two.
and just replace the cat. or install a sparkplug anti-fouler between the secondary o2 and the exhaust, that sometimes works.

 

Alright that sounds pretty decent. Do any of you know about aftermarket cats or is OEM the best choice?

 

rockauto sells catalytic converters. if you're gonna buy one brand new and look for future performance, get a high flow cat to maintain emissions. i believe Magnaflow produces some.

 

I always heard aftermarket cats always have problems. Any truth to this or is it based on opinions of people?
