i have stock manifolds on my 90 chevy silverado with a 350. im putting true dual exhaust but the manifolds have a 2 1/4 collector but im wanting to do atleast 2 1/2" pipe all the way through maybe 3" would it be easier to just stick with the 2 1/4 pipe all the way or is it just as easy to run bigger pipe if there a adapter to go from 2 1/4- 3". thanks for the help
the stock set up is the y pipe is 2 1/4" then turns in to 3" from cat all the way back so i dont see how it would hurt anything doing 2 1/2" true duals. im just trying to open it up a little and make it loud. im putting 2 super 44 flowmasters dumped at the rear end no cats
