Hi I m new here but I wanted to know how could I make my Astra gtc 2.0 cdti sound Sporty and loud not to loud tho 
And still being able to pass the mot 
Removing the DPF is a little more tricky these days with the MOT laws changing.

It all depends what you want to spend, and if you want to take the risk. You could smash it out and hope the MOT place won’t notice, which they probably will. Or, get a straight pipe produced to replace the DPF and keep hold of your DPF should you ever need it again.

I’m not 100% clear on the new MOT laws, so you’re best reading up on it before you do anything with the DPF.

A start could be having the back box/ silencer removed. This will make it a bit louder and a bit gruntyer and the DPF will remain in place.
