Does the itr header fit into the 94-01 integra GSR without problems? I was wondering if the header will fit right up to the cat or do i have to get another pipe to connect the header to the cat? Your replies are appreciated. Thanks
a true JDM ITR header has a 2.5" collector that goes to the cat. USDM is only 2". other than that, I believe it bolts right up. I could be wrong though.
Thanks for the replies. What types of catalytic converters should i use for this set up or what modifications do i need? Do i need to make the modification to the cat where it could bolt up to the 2.5 collector? Thank you
