hi guys soz again. um i have a peco big bore 4 sitting in my garage and was thinking of fitting it to my car but i have a few questions . i have bought a new back box already form ebay and had it installed its from a shop called gt3 exhausts and its the oval one. but to me its not as loud as i wanted.and low down the revs its not exactly a deep tone but when i get to 20mph is when the deep tone starts. are the peco big bore exhausts loud ? and are they any good? its black with peco big bore 4 written on it . its 4.5 inch outlet from one edge of the outlet to the other . and its a straight through if u get wot i mean. its basically a cyclinder. has anyone fitted this back box to their car . or has any one got any other suggestions that would be better or louder.
cheers
