Need suggestions for exhaust
Living in Northern VA, trying to mod my exhaust but I am unsure of 2 things:
Which combination will bump up my power and how will it affect my Virginia emissions test.
I bought an active autowerke axle back that I've heard on a neighbor's car and loved it but I want to combine it with either the midpipes or downpipes.
Will I get more power with the downpipe replacement? I am aware that the axleback is more for sound although the Active autowerke provides a little bit of weight reduction.
Another option is to leave the stock DPs but replace the midpipes when I install the axle back.
So again, which would yield a little more power? My guess would be that the DPs being closer to the turbos would provide a little more flow. Am I correct?
I don't want to do all 3 (DPs, MPs and axle back as I think it will get too loud).
Lastly, I want to know if this will drastically affect my Virginia emission's test? Anyone know.
Thanks for your suggestions.
