Think you do as the exhaust gasses cant be released right under the car, got to be from out under the car.

I thinks.

A 1.2 corsa without a backbox doesn't sound better, it sounds like a 1.2 corsa without a backbox.

you dont have to have a back box, only if you have the exhaust extended so that the exhaust gasses come out not under the car. thats what im gona try and get a pipe made up so that it has the propper x14xe exhaust tip on so it looks standard but in essance its removed the restricter

You have to have a backbox if you want to pass an MOT.

Honestly, dont bother, my friend made a makeshift backbox for his 1.2 16v corsa C from a piece of flexi pipe and a halfrauds pipe trim and it sounded gash

My brothers old Corsa didn't have a back box. Just had a centre silencer and still had the CAT. Passed MOT without any problems.

Really loud cars sound awful. Really loud slow cars are an embarrassment to the owner.

doesn't it also look a bit stupid without a backbox, and yes it is illegal not to have one due to gases not escaping correctly, you'll loose compression too, all it will do is make your car slower
