Thanks for the quick replies Guys.
I'm guessing the Stock exhaust should be OK to pass under the 90Db, hence why I'm on the search for one. The guy who had the car before said even with the silencer for the N1 (Which I have, just not on the car) that it still didn't pass his EPA test. I don't have a front mount, or Pod, only a replace panel filter which I'm guessing should be OK. The Blow Off valve is also a Greddy item, but it's plumbed back so I imagine that shouldn't be too much of a problem?
as far as the SAFC goes, I've got some sort of Diver Air/Fuel controller thingy on there, but with the Stock exhaust and BOV plumbed back, It should only need to sit there turned off. Is it a good idea to stash it anyway? Even if it's sitting there not doing anything? (I'm guesing it is, in a better to be safe than sorry kind of way).
And yeah, I'm guessing you're right INASNT, The canary I got about a month ago would've been the lead up to this.
Edit: Scorp - I just got mine sent in the mail. On the back of the EPA form it says you don't need to be pulled over to be reported by the police (Or something to that effect), but in your case I wouldn't worry about it. As INASNT said, mine is prolly an extra bonus from the Canary I got not too long ago...
