ive got a crack in the last section of my system, i dont no much about exhausts and wot the different parts are called but its the long thinner tube that conects to the large tube in the middle of the underneath or the car, there is a crack jsut b4 the conection, the engines fine etc... and its still goes well, mayby a slight loss in power due to pressure etc but nuthin drastic, it just sounds a bit shite, and im wonderin wot i can do bout it, i was thinkin that praps i need to get it welded?? but a the moment i dont have the money for that, ive wrapped a cloth round it, but obviously thats not really doin that much!! so wot can i do, without any expense?? and when i have the money can u buy just that thinner tube and get that fitted, if so were from and how much? thanx :D
