I'm planning on installing a JDM DC Sport header with a Carsound cat. I want to keep my cat back stock. What size flanges do I need? Or will the muffler shop not have a problem mating all this up? Does it matter what Carsound cat I use?
I have a dcsport header and 2.5 inch converter right now. Be aware that the jdm Dcsport header runs lower than your engine does. If your car is lowered alot, look out.
I installed a Spoon N1 on the stock setup. It was loud out the box. Then I installed the DC Sport JDM header with Omni Power test pipe; no difference in how loud it got, but it was loud at the low RPM's. Any suggestions on an aftermarket mid section (with OEM flange on the rear section)?
