Asked on the exhaust page but no response! I am doing a dealer big bore with stock heads, se cast pistons, 204 cam, and a sert, should I let the stealer put the catalysts on or do you think they will put the Hard krome t-rexs on without a problem? I could always do it when I get it home but then I will need a map.Any of them out there for this build? Thanks
