Peugeot 407 Flex Pipe

A loud blow or tick that gets worse on throttle lift, an exhaust smell in the cabin, vibration transmitted to the floorpan, and visible fraying of the braided mesh. On 206 and 308 HDi models the flex is always the first exhaust section to go.

Real SA retail — generic flex pipes run R190 to R850 through Liatros Performance, RMS Performance, Easyflex and Boss Auto. Junk Mail and AfricaBoyz carry Peugeot-specific units. Labour is one to two hours for cut-and-weld. Send your VIN for a quote.

Once the mesh is torn or the inner corrugated core is cracked, welding rarely lasts — the repair fails at the weld boundary within weeks. We always cut the old section out and weld in a fresh flex pipe. Total replacement cost is modest.

SA retail for generic flex pipes sits at R190 (budget Liatros) to R850 (RMS Performance premium stainless). Peugeot-specific replacements through Sparesboyz or AfricaBoyz are typically bundled with a full front-pipe repair. Ask for a fitted quote.

A failed or seized flex pipe is the top cause — with no flex absorbing engine movement, vibration transmits straight into the system and body. Other suspects are failed engine mounts and a rattling heat shield. Check the flex first; it's a two-minute inspection on a ramp.
