hello i have reached a point in the car build where i am considering the e-30 tune from stratified ( currently running cobb ots stage 2 map 91oct)
i will be definitely doing a downpipe in the next 3 months along with the ported voodoo manifold. Should i wait on the tune and do the dp first or will it not make much significance at this point? i currently have all the cobb stage 2 kit installed(just missing exhaust and dp)
also i dont have emissions testing where i live so i was considering the voodoo downpipe as well , but will a catless dp make the car more smelly (ie smell more exhaust gases?) while idle versus a catted. i dont smell nasty fumes currently on the stock dp.
