A friend of mine has got a vts with a 4-2-1 mani magnex backbox , straight through exhaust with silencer removed, and it shift been in a few vts,106 GTis' etc.. and his goes really well. was thinking i've got a C2 GT with 4-2-1 ashley manifold (with de/cat), magex backbox and was thinking if i had my center silencer cut out and pipe put in place would i benefit from it would it loose back pressure etc....
Thanks Ross.
