320BHP Mazda 3 MPS CATLESS DOWNPIPE SOUNDS MEAN!!

Exhaust set up - Catless downpipe, 2nd res and Cat delete. Stock backbox.

Sounds good to me.

[@joshuacampbell7435]

Sounds amazing

[@joshuastunt571]

Have you got any links to the exhaust parts you’ve changed

[@BebopbeypBBB4th]

What mods are you running? And what stage are you to get 320BHP stock KO4

[@DJONDEX]

There are no stages to these cars where I'm from. It's was just a catless downpipe, resonator deletes, uprated top mount intercooler, high pressure fuel pump internals, cobb accessport v3 with a custom tune by Justin Heath, best MPS tuner here in the UK ✌

*What's wrong with the exhaust kids? It sounds terribly dated and loud, it seems that the engine's really strugling. Get the exhaust fixed.
