Can anyone comment on how much of in increase in in-cabin noise I would experience from a Buschur intake, UICP and LICP and from a AMS FMIC?

In short, I had purchased a 2008 X new back in 2008 and daily drove it for four years. My only real mod was an Accessport, and I had no issues with the noise levels.

Fast forward to today, and I recently purchased a 2010 X that has the mods listed above as well as a Buschur Crossflow exhaust. The in-cabin noise ("boomy" upon acceleration and deceleration) is getting to be annoying, and I'm trying to isolate where it is coming from. I was thinking of adding a resonator to the exhaust, but since it's one of the quietest exhausts out there I'm not sure it will make a difference. It sounds like the noise I don't like is coming from the engine, but it's hard to tell...

Anyways, before I get a resonator, I was just wondering if anyone can comment on how much more noise would be added over stock by the addition of the intake, FMIC, UICP and LICP.

Thanks for any assistance.

 

The intercooler and intercooler piping won't increase noise. The intake will increase the sound of the turbo spooling.

 

Thanks. That's what I thought (and is the feedback I was hoping to receive).

The sound I'm trying to eliminate sounds like noise that I would typically associate with an exhaust, but it seems to be coming from the engine area which is why I asked. I do know it's sometimes hard to pinpoint where sound is coming from in a car due to resonance issues, etc., and I suspect that issue is amplified in the Evo with its minimal sound dampening...

 

I'd note the noise at a cruising/constant RPM on flat, then that same noise at same RPM on a hill. If it's louder going up the hill for the same RPM and throttle position, it's the intake side.

For my X, the ETS intake makes more noise than my ETS TBE (v2Quiet).
