I have a 1.0 but I think my info will be useful to you anyway. I wanted some sound, I didn’t want to wake the neighbors when starting the car in the morning. I ONLY changed the rear muffler for a Duramas (homologated) and I swear on my life I don’t understand people who say that changing just the rear one is useless and you won’t notice it; you notice it a lot, the sound I’ve gained is huge. There are even times I regret changing the muffler, although it’s true the sound is awesome. Like I said, don’t go crazy with straight pipes and all that because it’s nasty; go for something homologated, it’s more than enough. Gas
