I DONT BELIEVE IT!
Ok I went down to Cummins today to get a set of filters. Started talking to one of there head mechanics . He told me removing the silencer ring actually affectsthe turbo's performance . He said the ring is there to funnel the air into the turbo making it a smooth constant flow . He said once you remove it . You loose the funnel of air going into the turbo then it actually doestn run as iffecient as it should . He said think of it as pouring oil into your truck with a funnel . Then take the funnel away and pour ... ......Makes sence to me Once you think about it . I'ed rather have less noise and more efficient :thumbsup Then more noise and less efficient :thud:So as of now my silencer ring is back in . Any one have any thoughts on this ??:thumbsup:beer
