my crx has an aftermarket cat on it, and it seems that cat has recently began to leak where it connects to the exhaust at the 3 bolt flange point. i think a tiny hole has developed there. im looking for a replacement for it, does anyone have recommendations? it seems that a magnaflow is a direct oem replacement that people seem to use but are there any others that are relatively inexpensive? my exhaust path is fully stock. also this car is my DD so i need a cat on for emissions reasons before anyone suggests totally removing it.

 

Magnaflows new series its name escapes me at the moment will flow 250hp loss less. These were bought for my camaro, 500 hp no loss ftw

Catco is what I use on my Honda wasn't more then 100. I've seen carb legal cats on ebay for 70ish.

 

You said it seems to be leaking at the flange ? Have you tried replacing the flange gasket to see if that is your problem. Thats such a cheap fix that you will want to try that first before you drop $ on a new cat.

 

im going to check the flange first, however im at school right now and dont have access to jack stands, tools etc. nor do i have time to mess around with it ATM. so I am just trying to figure out possible options to fix my problem when i go home for break in a few weeks and can work on the car. i really dont think its the flange though, the car got LOUD after this leak developed, so unless a bad/rusty/old flange can cause that im pretty sure the cat has developed a small hole near the 3 bolt flange. the car basically sounds like im running an open cat to a certain degree, and i can hear the air escaping from that cat and flange area when i rev the car.

 

anyone else comments/suggestions?

 

they got cats on ebay, i dono ne thing aboout them u might wanna do some research but there pretty cheap
