Just wanted a diagnosis. Here are the symptoms.

1) A slight chirping coming from just below the windshield. Very faint at idle RPM's. Seems to get louder as the RPM's go up, but when I put it in neutral and coast at higher speeds, the chirping stays loud. I believe it has to do with the state of the road. When I go over small bumps in the road (usually at higher speeds) the chirping becomes louder.

2) A rattle coming from the back left side of the rear hatch. The trunk release is already taped up, and I even insulated the tools for changing the spare tire. It almost sounds like the glass is loose (I know it is not).

Now a mod related question.

Firstly, I have no current mods. Can I just drop in a modified airbox w/ 2 K&N cone filters, and a downpipe w/o remapping the ECU? I know the "limit" is 3 mods, but that seems like general speculation versus confirmed fact.

Thanks for the help.

You should be fine with those two mods.

 

They will out handle just about every car on the road, including most supercars

 

I had a downpipe and the APEXi intake on my car for close to a year without an issue. You should be fine with those two mods. But get a boost gauge and make sure you're not spiking or creeping at all. Every car is different, so your turbos might respond differently than mine did. I had no spiking or creeping, but my turbos had ~100k miles on them at the time.

 

How many miles do you have? That may be why things are rattling.

 

Just about to hit 33k on original engine/turbos

 

I have the same window squeak/chirp from the windshield. I've discovered that the dash has lifted up a bit and now makes contact with the windshield. This occurs at the point where the passenger side A-pillar meets the dash.

The chriping is coming from the dash rubbing against the windshield.

I'm going to try and remove the A-pillar and see if I cant get the dash to stick back down.

 

the chirping/rattling could be the hood/hatch need to have the latches adjusted down a little due to body seals/rubber bump stops collapsing over time

 

My hood hinges chirp. A shot of WD40 solves the problem, but have needed to do this several times.
