HJS ECE Downpipe 3″ BMW 135i 335i F series 306/326 hp 90812035 N55B30A

The downpipe is perfectly suited to standard vehicles as well as those with increased output.

Fitting this downpipe results in a slight increase in power and improved throttle response.
Another decisive reason to buy this downpipe is that exhaust gas temperatures fall and the turbocharger is relieved.
