If you’re looking for maximum power from your Impreza, this is the only downpipe you need! Japspeed’s ‘bellmouth’ 3 inch downpipe is a much larger bore and also removes the primary catalytic converter improving power and turbo spool. With the downpipe fitted alone, Japspeed has seen gains up to 30bhp over the standard restrictive item!

This bellmouth downpipe has a 3in bore all the way through with 12mm thick flanges narrowing down to a 2.5in bore at the outlet. Due to the nature of this downpipe, it will not pass standard emission ratings and as such is sold purely for off-road use only. As with all Japspeed products, all gaskets and parts for fitting are included.

Key Features:

• T304 mandel bent polished stainless steel.
• CNC machined flanges for strong, solid support and an accurate fit.
• Fully TIG welded.
• Large bell mouthed opening for maximum gasflow.
• 3 inch (76mm) bore all the way through with 12mm thick flanges narrowing down to a 2 1/2 inch (63mm) bore at the outlet.
• Perfect fit with a standard or aftermarket catback system.
• Lambda bosses fitted to accept original lambda probe.
• Improves BHP and torque over the entire RPM range.
• The most cost effective way of releasing power from your car.
