I have a Gsr engine in a 98 ferio and I want to put a header on it. I bought the DC 4-1 header (not jdm). The header is for a Type R but it should fit better because it is longer (from what i hear). I have the part number for the header gasekt that connects to the head but I am not sure about the part number for the cat to header gasket?? Do I even need that gasket if i don't have a cat??

Also...will this be a pretty straight forward install since I don't have a cat or is it going to be a pain in the ***?? is there anything else i should purchase for the install?? will i need to have a muffler shop make an extension??

thanks in adavance for your help.

 

cat to header? no gasket install should be easy but why no cat??

i thought there was a gasket where the header attaches to the catalytic converter?? is that only for the 2.5" collector??

would you recommend that i get a cat or is it alright the way it is now?? i never knew that it would be a problem but if it is I can get one.

thanks.

 

in ca you wont pass smog without cat. and the header should just have a rounded edge on it where it meets the cat. there is a gasket at the rear of the cat

 

I would definitely recommend you getting a cat, especially living in CA.

there is a "donut flange" you use for where the header meets the cat.

 

i know i wont pass smog but is there a benefit to not having one as compared to having a carsound?? so there is no gasket to install on the bottom?? is it only the jdm header that has a gasket down there??

 

look at the header where it meets the cat. is it slightly rounded??

thank you FdOoUoRr... is that a pic of a jdm 4-1?? i have a regular 4-1. does anyone know how big the opening is?? my new header looks like this one but i don't think the opening is that big. does anyone know the part number for the donut flange??

thanks...i looked at the website and i am going to buy one of those carsounds. I dont know which one to get though. 2 1/4" all the way around or 2" to 2 1/4." Does anyone know how large the DC header outlet is for the non jdm applications?
