i just took off the heat shield to exaust manifold on my 96 civic dx hatch and saw that it was cracked. what would be the better choice to replace the stock manifold or go with the ex manifold. how would i fit a cat after the ex manifold setup. which would be cheaper

 

Go with the EX manifold, the DX one will always crack.

 

Depends on the what manifold, what state you live in, and what your looking to do. Best bet would be just weld it.

 

how would i fit a cat after the ex manifolds

 

get an EX manifold and EX cat and have a muffler shop weld it on Your catalytic converter will be welded onto your remaining exhaust system UNDER the car Mine's cracked as well but I just had it welded shut and its doing fine so far, been going strong for like 4 months

 

thanks for the help

 

would the cracked manifold make the engine light come on

 

hey i got the same problem with my Ex (canadian built) with a d16y7 . I was told that changing to the usdm ex exhaust setup will cause your car to throw an engine code and run rich !! thats why i am looking for some info as well !! anyone know what we can do to fix this problem ?

 

someone help us

 

my cracked manifold didn't make my CEL go on but it did make annoying noises and to answer the other guy, no it shouldn't throw a code or anything, you'll have to extend the second o2 sensor to reach the cat (which will now be UNDER the car) or I think you can run an o2 sim (someone check that for me) and you'll be fine

 

Alright , any ideals if a d15b7 Exhaust manifold and downpipe could fit ? cuz i got a couple d15b7 EM lying around .. Thanks for the quick reply

 

if my catalytic converter is clogged could that throw the cel
