It uses mandrel-bent piping with an oversized resonator and packed muffler, so you get a cleaner tone without making the car sound harsh and raspy every time you get on it.\u003c\/p\u003e\n\n\u003cp\u003eThe entire system is made from 304 stainless steel and bolts to the factory mounting locations on the 1988-1991 CRX. The 2.5-inch piping works well for a modified D-Series or B-Series setup and also gives you room for a future engine swap or turbo build.\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003eFitment Information\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e1988 Honda CRX DX, HF and Si\u003c\/li\u003e\n\u003cli\u003e1989 Honda CRX DX, HF and Si\u003c\/li\u003e\n\u003cli\u003e1990 Honda CRX DX, HF and Si\u003c\/li\u003e\n\u003cli\u003e1991 Honda CRX DX, HF and Si\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment Note:\u003c\/strong\u003e Made specifically for the 1988-1991 Honda CRX chassis.

Check the factory rubber exhaust hangers while the original exhaust is removed.
