[QUOTE="Flyer58, post: 432968, member: 18629"] I went through Rock Auto to get a full Walker exhaust and overall very pleased with the fit and price but there was one problem with the head pipe near the O2 sensor collar. They crimp a flat spot in the pipe to weld the collar on. This crimp on the walker was too much and there were MIG wires sticking down into the tube. I called Walker and they said the crimped pipe should be no less than 1.75 inches, mine was at 1.5 inches. I exchanged it for another through Rock Auto without any trouble and within a week had the new head pipe. BUT it too was crimped down to 1.5 inches. I called Walker to tell them there's a manufacturing issue, not sure if it's fixed. All other bends and lengths were perfect. Hangers and clamps were included.
