Heat shields necessary?
Ok so I ordered my Jdm Itr header and was wondering if you guys think I should buy the upper and lower heatshields for it. Are they really necessary? Also, I ordered a new 2.5" carsound cat to fit the header, once i get my rsr exmag catback which i believe is 2.36", how is it going to bolt on to the 2.5" carsound cat? Is a muffler shop going to have to weld on a smaller flange to the cat?
Thanks in advance

Most after market headers do not run with heat shields. However, if a stock look is obtainable I would do it. For reasons of smog, selling the car, or getting puled over. An after market header sticks out like a hard on.
As for the exhaust bolting up to the cat. I believe 2.36 is only the diameter of the piping. The flange is not measured. If the cat is designed for your car as well as the exhaust and header then all the measurements should be for fit. Unless there is a disclaimer advising that modifications will need to be made. But if everything is bolt on for your yr. car then everything should meet up. Now with the ITR header, I believe some modification is needed to fit a GSR, but not the non-vtec Integras. So length wise some changes may be needed and maybe some re-positioning of flanges, but I don't think you will need new ones.

What do you mean the part where the cat meets the exhaust pipe. Are you talking about the flange on the exhaust pipe or the pipe on the cat?? Because the both sides of the cat are 2.5" and since the diameter of the rsr piping is 2.36" that means it wont bolt right up. Unless the flange on the exhaust pipe is 2.5" no?

I know I'm a day late, but I would strongly recommend buying the heatshields for the JDM ITR header.
That little bit of camo will save you a lot of grief if you get stopped.
