Recommended intake/exhaust combo
Hey guys, I'm new here. I'm about to get an 05 EP3 and I was wondering what CAI and exhaust you would recommend, not necessarily at the same time. I'm on a sort of tight budget, thanks

"Search", they'll say...
What are your long term plans? I'll post up what I think works for bolt-ons and can be good for a swap. Building a high-rpm screamer or adding boost would have different requirements.
Intake setup that's inexpensive yet improves on the stock box? The stock intake box has its benefits, including protection from hydrolock, no heatsoak (never see a heatsink made of plastic, do ya?), and quick throttle response. But, it has two drawbacks. Its intake snorkel, while not exactly in the hottest part of the engine bay, isn't in the coolest, either -- it's tucked behind the radiator, next to the battery. Buy or fabricate a duct (something similar to the T1R, linked below) to get fresh air from above the radiator.

The other possible drawback -- really more of a compromise -- of the stock box is its internal baffling and resonance chamber designed to keep down noise. Open it up and cut out the bits that impede airflow. While you're at it, might as well get a performance-oriented air filter.

Do those things and you'll get the effective benefits of the Mugen box (the best circuit/auto-x intake for daily use, IMO) at a fraction of the price without losing the good points of the stock intake system.
Exhaust... hmm... how legal do you need to be? If you want to keep things legally simple, go for another Honda cat or an aftermarket high-flow model. The link below is to my thread that involved installing a stock Type-S header-cat combo onto my EP. Legal, OEM fit & build quality, flows much better than stock. You could also use a JDM DC5-R header-cat combo, which is a true 4-2-1 setup good for high RPMs, or even anything that's labeled for use with the Type-S.

The stock muffler flows very well already; the midpipe, however, could be replaced by something with a larger diameter. You could go with one from a Type-S, an aftermarket midpipe, or use a whole catback designed for the EP3 Type-R.
All of these reasons, taken together, are why I went with the setup I've got now (Mugen airbox, Type-S header & cat, JDM Fujitsubo catback). Looking back now, I could have easily gone cheaper, but I'm quite satisfied with the results I got.

Re: Recommended intake/exhaust combo (Jeenyusss)
Sounds good so far.. it really depends on how much money I can save after I get the car.. I'm putting a down payment on it and I have to pay it off monthly, so depending on how much it costs to pay and how much i make, it'll take some time to get certain things
