Alright, so I bought a 3 inch catback system for my s14, its a ka24de n/t, and I also got OBX long tube headers+downpipe+test pipe, those parts are all 2.5 inch, are the flanges going to meet up, or should i take out the test pipe, cut the flanges and weld in a 3"-2.5" adapter??? Any Ideas, i havents seen the header down yet so I dont know, im just trying to get prepared for this weekend to do it.
