you know i never thought bout if it would make a differ to have dual exhuast with a nitrous
setup. id just get the duals first hell its a nice upgrade for sure
and def def 100% get tuned by a TUNER in person seriously not every car reacts the same to a nitrous setup
i went with a flipchip i have no clue whether thats what your getting or what but i got tuned nicely N/A and even nicer with the nitrous.
have fun i know i did when i had the 100 shot woot
