How would you fit a DC JDM 4-1header on a usdm catalytic converter?.

One of my friends suggested to use an adapter.

Thanks for your help guys

 

contact anyone the board. im pretty sure someone can help you. i know for fact that inlinefour.com can help you

 

There are flanges available from several shops, and I'm sure Dave at SMSP could definately help you as well. However, if you're retaining the stock cat. (which is pitifully small) you might as well just buy a USDM spec. header and save the expense and trouble of modifying the cat.

 

Just buy a 2.5" cat or run a 2.5" test pipe with it!!
