Installed a jetex cbe the other day doesn't seem very loud. Hoping to get a atp catless downpipe fitted Wednesday. Is going to make much difference? Or am going to have to get the backbox cut out as I want it to pop and bang on over Rev? Thanks views please any got a jetex cbe and catless downpipe?

There are a couple videos on Youtube of Jetex catback + catless downpipes. Try also searching for Mazdaspeed3 as well as MPS.

You'll need an uprated fuel pump if your going catless.

If you want 'pop and bangs' I think you need to get that tuned into your ECU.

I thought 'pops and bangs' only happen if your over fueling the engine, and its unburnt petrol detonating in the exhaust.
