I pulled plugs , they have no color. Look like brand new. Only change made on car was 2 1/2'' exhaust. Would new exhaust lean car out that much?

Anytime you install a hotter ign system you more then Likely need a colder range Spark plug . And you might have to step up the Jets just a little . But you also should see were your fuel pressure is . As white as your plugs are I would go with a set of R43TS A.C Plugs and see how they burn . Try them with a .040" gap .
