RE: Dually
Ok, i got a qoute on the exhaust up grade that sacicons recommended. The shop said that 2.5 is not neccessary at all. They said a 2 1/4 will be better. They also said that there is virtually no back pressure between the engine and cat. So they recommended that just upgrade to a higher flow cat and pipes and muffler on. I asked them about headers too. THey said that you dont really need one unless you got some serious mods. they qouted me ruggly $500-550. sounds fair to me
