I have a 96 integra Gsr. I acidentally bought a one piece header for a 2000-01 Gsr. Obviously it doesnt bolt right up. Is the only difference the extra length before the cat? Can I just take the header to the exhaust shop and have them cut it down to the correct size? Can someone tell me the difference in length? thanks

 

actually the only way to do it is put it on and den bring it to a muffler shop.cuzz they wont know where to cut or what to add yup.
