Product Details

What It Helps Repair

Installation Notes

Compatible With 2002-2006 Acura RSX and 2002-2005 Honda Civic, excluding UK-built Civic models. Verify inlet and outlet orientation, flange style, and overall length against the original exhaust before installation. Because this is an OE-style muffler assembly, proper alignment with the existing exhaust hangers and pipe routing is important for a correct seal and fit.
