OK guys hopefully this is in the right place.. anyways I am curious which exhaust you guys think will give me the best performance on my 86' n/a 13B 5spd

I am looking at the Racing beat TRUE dual header, true dual, presilencer, Y pipe out to a pair of aftermarket strait through mufflers.

my other option is the racing beat header 2 to 1 then a single racig beat presilencer to a Y pipe then to the strait through mufflers...

I am going to be on the 13b n/a for a while, plan to port the intake, runa safc to pull some fuel etc..

which exhaust should I go with?
