BBR-GTi are well renowned tuning specialists that have recently taken under their wing, the sporty Mazda 3 MPS Mk2. With a sprinkling of stardust, they have created 3 stage conversions that realise the true potential of the 256bhp 2.3L turbo charged engine. We won't go into all the detail here as that is really for the experts at BBR to talk about [www.bbrgti.com]. However, the important thing is, that as part of their Stage 2 conversion, BBR-GTi decided to incorporate a Jetex high flow panel filter and 3" stainless steel cat-back exhaust system.

In their own words:

"...To optimize inlet flow and provide superior filtration BBR replaces the stock paper airbox element with a high flow performance filter.

"...For customers seeking a sportier exhaust note a BBR stainless steel cat back exhaust system is available as an option to compliment the Phase 2 upgrade.

Our cat-back system connects to the OE downpipe via a 2 bolt flange. Pipework is 3" outside diameter to ensure maximum gas flow. Bends are mandrel were possible and the tailpipes are rolled in 114mm in diameter which fits the OE cutouts perfectly. Our exhaust compliments the aggressive styling of the Mazda 3. This exhaust is exclusively available from BBR-GTi either as part of their conversion or as a stand alone performance upgrade.

Our performance filter is a cost-effective, environmentally friendly and fuel saving aftermarket part that has significantly better filtration than the standard OE paper filter, and because it has a large dust retention capacity, will perform long after a paper filter becomes inefficient. It is washable too, so there's no need to throw it away! Some performance improvements can be expected, and in conjunction with a conversion such as BBR-GTi's, the Jetex cotton gauze filter helps squeeze every possible BHP from the engine.
