hi3afp 0 Posted February 6, 2007 HI A few days a go i notice that mi 1.6 cti start to make a loud noise fron the exhaust, it has no holes or cracks in the system, but i think noise come from the back box. I will like to get a replacement but here we have only a few ctis ( about 10 in all the country ) and no gtis . So the spares parts are not easy to get. Can i use the back box from another peugeot models ?. I have a xu10head fitted, i don't want to lose power, not too loud sound. this are the options: 205 junior ( i dont think so) 405, not mi16 206, not gti 306, not gti 605 406 An aftermarket back box, not designed for the cti. Gracias... Share this post Link to post Share on other sites
