Exhaust manifold leaking

Been a while since i posted original member since 2003 . I have a exhaust manifold leak that quiets up after it warms ..besides annoying does this cause any performance issues ? its a old truck not sure if i want to tackle the old rusty bolts.!!

A leak has the potential for diluting the exhaust which the O2s reads to adjust fuel mixture. So yes it can affect performance. Show the old girl some love and fix her up.

It can effect the mpg of it's bad enough. Most times it's just annoying. Pb blaster a week prior and it will come apart nicely for you. Get new bolta and new gaskets it's likely it's just a manifold seal leak on the head very common

A added incentive to fix the exhaust leak !! just got off the phone with Borla sent them a few pictures there ending me a complete dual exit cutback for the old girl this will be my 3rd one since 2004 have a rattle in the exhaust and tips. Greg I was thinking headers a long time ago but it was a work truck all lettered up Lennox . At 350km don't think its worth the cost not to mention the Ram 2500 manual shift is a bitch to fit with headers I'm told
