i think this happened what will it do

91 crx si with b16a1 with exhaust with cat and intake 255 fuel pump

 

it'll slow you down like a ****

 

can it happen

 

normally when a cat is clogged, you will here a pinging sound when you turn your car off...like i am hearing now...

 

heh if it melted shut you have no exhaust flow not a ping but a kapow! when that cat pops

 

look under ur car after driving it is ur cat red hot???? i mean red like red then that means its melted shut just get a new one while ur at it get a high flow cat

 

I got the Catco High Flow for $100 @ summitracing.com

 

I am using the same one with my b16 swap and it has not failed or melted shut.

 

You have 3 options:

1. Get a new cat ($$$)
2. Take off your cat after it has been sitting a while. Get a long metal rod, and poke as hard as you can to bust it out (No $$$)
3. Sell me your 255 fuel pump for $25, then refer back to option 2.

I say go with option 3, that seems like the best choice

91civic,

Which would you prefer? I have a test pipe on it right now, but am debating a high flow cat. I do not have emissions in my area, so they're not a problem. Should I stick with my test pipe or get a high flow? Any major differences in performance between each of them?

well it is a high flow cat it started with this wistleing nosie sorry for spelling it sound like its right by the cat but i started to no have power when that started. Know i cant rev past 5

 

sounds like your cat. unbolt it(pain in the ****) and then start it up ... pop your ear plugs in and rev it and see if itll go past 5k. Then you know what your problem is. unbolt other side and take a pipe and beat up the innnereds

 

$100?!?! I paid $50 for my 2.5" Catco High flow

 

Yeah, I also only paid around 60.

hmmm.

Great quality cat's BTW

 

where u guys get em for 60??? id like to find out

 

the direct bolt on are $100 each while the universal (weld-on) are around $50-60.

 

Summit. This was about 4 months ago so the price may have changed.

Yeah, it's the 2.5" weld on one, not the bolt on.

 

I had a straight pipe on my car before I got the cat and it was extremely loud and raspy. So i bought the cat and the noise was toned down substantially. I didn't notice a performance difference either. I am still running the same times. I would personally recommend a high flow cat unless you like the loud noise or you are running forced induction.

 

problem fixed melted cat

 

I also have a Catco cat, has not failed yet going on 2 years. Now it has a B16, lets see what happens.
