i have a 97 gsr. i am gonna be getting the DC 4-1 header with 2.5in collector and my question is will this header bolt straight up to my stock cat without any problems? i ask this because my stock header and cat are kinda small and dont wanna get the header and then it not fit on my cat. lemme know thanks

 

i am assuming you're talking about the DC jdm 4-1 header, 2.5" collector will not fit your oem cat, you need to get a custom cat and catback to benefit from the 2.5" header,

 

i already have an apexi n1 catback on my car. what cat will i need to get and where can i get it? i need a cat that has 2 o2 sensor holes for my stock sensors

 

does dc sports make a 4-1 header that WILL bolt right up to my stock cat?

 

yeah i just ordered a header from http://www.prostreetonline.com and its a dc 4-1 and fits directly to my stock cat. Any dc header will fit a stock cat....the only header that doesnt is the JDM...but order from prostreet they are good

Contact SMSP. Dave can provide you with a 2.5" cat that will allow you to bolt the JDM header right up to your N1.

Dont be lazy. Replace the stock cat. A muffler shop should be able to bolt a 2.5 inch cat to your JDM DC header and then weld a flange so it can connect to a smaller diameter exhaust.
