hey guys i have the tanabe catback, and the stillen HFC. i love this combo, sounds sickkk. anywho the only thing in between thats stock is my y pipe. i was looking for a 2.5 inlet because both the midpipe and the HFC are 2.5in. I think the stock 04 g35 sedans y pipe is 2 or 2.25. correct me if im wrong. i am just looking for a 2.5 inlet. not looking to drop any heavy bills on this. under $80 bucks maybe. let me know what i should be looking at. i need to get a y pipe asap cause the stock pipe is not letting my HFC flow properly cause its smaller.
