I have a peco backbox, with a de-cat AND straight thru centre section! Think its the JP4 box. (4"slash cut, burnt tip)

If u de-cat urs its all depends on how loud it will be. What engine and what peco backbox have u got?

In my experiance, i couldnt here my backbox will all the silencers in, so i de-catted it, got abit louder, but wasent loud enuogh. So i put a staright thru centre section on, its just right now

like rikki said the only way it will pass is if the garage looks the other way or of course if the car is old enough to not have a cat in the first place

they shouldnt pass the MOT as the car physically has to have one to pass, i think some garages will dismiss this if the emissions are okay which without a cat this is very unlikly,

you can put it back on for MOT, but what happens if you get pulled into a roadside check? you can't put it back on for that,

to be honest if you want it louder you would be better off getting a smaller midbox fitted, dont remove it because it will sound shite

Im thinking of decatting my corsa with the Peco Exhaust i have on and before anyone starts i like the Peco and im not changing it :P

I want to know what my car will sound like if i decat it.....will it be loud and crap sounding or will it sound just nice with a nice wee rumble but again not too loud.

Anyone any sound clips off a corsa decatted with a peco ?!

Help please :thumbs:
