To the best of my knowledge, there is no Cobb AP map for any after market intake, and they make a significant difference in intake flow.

If you BOV is anything other than recirculating, dump it.

If all you have on the exhaust side is an axle back, it is unlikely to be anything turbo/wastegate related.

I can't imagine anything on the left side of the engine that could make noise... Intake and exhaust is all on the passenger side... It is likely just more noise due to the intake which is no big deal, but unless you are tuned for it, I would remove it as well.
