ah.....ok...........but don,t be afraid of them if you buy a quaility reducer and its installed right you should have 0 issues with it........i have put many in over the years but only when the customer let me buy it...........when i have a customer walk up to me and hand me a reducer that they got the deal of a lifetime from e-bay on i refuse to install them even if they put it in writing that they won,t hold me responsable..............i have lost a few customers over the years because of that but in the end i sleep well at night and have even had some come back after thinking it over and having problems with their e-bay buy..............................
