What Are Peugeot 408 Downpipe?
The downpipe is the first section of exhaust bolted to the turbo on Peugeots like the 208 GTi, 308 GTi THP and RCZ-R. It carries searing exhaust gas into the cat and onward to the silencers. On SA performance 308s and RCZs it's the first thing owners swap when chasing power.

What are the symptoms of a cracked downpipe?
A loud blow or ticking noise at idle that gets louder on throttle, a whistle as boost climbs, black soot staining near the flange and P0420 cat-efficiency fault codes. On 308 GTi THP and RCZ-R the cracks typically start at the turbo flange weld.
Can I drive my Peugeot with a leaking downpipe?
Only briefly. A downpipe leak vents hot exhaust into the engine bay (fire risk) and fools the lambda sensor into misreading fuel trims. The ECU may go into limp mode. Fix it before it damages the cat or triggers an emissions failure on roadworthy.
Does a downpipe add power to a Peugeot?
On turbo models — yes, noticeably. A free-flow downpipe on a 308 GTi THP, RCZ-R or 208 GTi reduces exhaust back-pressure and typically adds 10-15 kW paired with a remap. Non-turbo Peugeots see almost no gain from a downpipe swap alone.
Which Peugeot models use a turbo downpipe?
All turbocharged Peugeots do — 208 GTi, 208 THP, 2008 1.2 PureTech turbo, 308 GTi THP, 3008 THP, 508 GT, and RCZ-R. Non-turbo 206 and early 207 1.4/1.6 naturally aspirated cars have a conventional front pipe instead.
