My 2.0 KRD Tib has the same exhaust manifold. This is stock manifold (cars with 1 cat)

does anyone know if there are any gains from these as compared to the cast manifold??

Yea looking under my hood it seems like a few inches you see a cat there. I will post a pic of it later to show everyone that has not seen one like that. My question is it ok to run without the heat sheild?? Have a friend trying to tell me that it will make the motor run hotter but that does not make sense to me.

NO no gains
Both the 2.0 and 1.8's had these, depending on production date.
Produced before 98/08/16 and you had these puppies

Produced after and you get the 1 piece manifold and cat combo

auburnfan- im pretty sure it owuld be okay to run without the heat shield. I heard from before that the heat shield is kinda useless and they keep your engine bay looking cleaner.

If its running one cat, doesnt that mean the exhaust that comes out is dirtier than 2 cat exhaust system?

Yeah, this manifold will actually act like a 4-2-1 header that you can get from OBX or something. Design is pretty similar. I bet they will give you a few ponnies smile.gif

It's true that if you have only 1 cat, exhaust gases coming out will be more dirty.

hmmmmmm........... i was wondering the same thing. Thats how mine look, but they are not as rusty as yours or discolored. Lol... I already thought i had aftermarket headers. Guess not

hmmm i guess j2s run cleaner than rds cuz i only had one cat

j2s with 1.8L are older cars, standarts back in 1998 on Emissions were very different than what they are now.

thoes are stock for the US spec tibby the korean spec is cast iron lump ahhhh

shit port them poshish them get them diped in crome or power coat them.
