Check with Apexi and see if they have any documentation about the noise ouput of the N1 exhaust on a Impreza.
In California, because of budget cuts, the officer does not have to actually test the decibel output of the exhaust but can use "good judgement" (fucking cock-suckers) to tell if it is in fact over the 95 decibel limit.
I'd say the best bet is to see if you can get something in writing from Apex about the noise output of the exhaust.
I believe the california code for exhaust noise pertinant to you would be section 27150.2
27150.2. The commissioner shall adopt regulations setting standards
for vehicular exhaust systems consistent with Article 2.5
(commencing with Section 27200). The regulations shall include, but
need not be limited to, the following:
(a) Provisions for standards for vehicular exhaust systems, based
on manufacturers' data and subject to any inspections and other
verification the commissioner may prescribe. The regulations shall
include provisions specifying that exhaust systems installed on motor
vehicles, other than motorcycles, with a manufacturer's gross
vehicle weight rating of less than 6,000 pounds, that emit no more
than 95 dbA when tested in accordance with Society of Automotive
Engineers Standard J1169 May 1998, comply with Sections 27150 and
27151.
(b) Provisions for the licensing of stations to implement this
section and Section 27150.1, and for the denial, revocation, or
suspension of any license for failure to comply with this section or
any regulation adopted thereunder.
The regulations may provide for the exemption of vehicular exhaust
systems where compliance with the regulations would cause an
unreasonable hardship without resulting in a sufficient corresponding
benefit with respect to noise level control.
