FWI(fender well intake) question. Exhaust(cat) question.

to my understanding, the PCM is pretty well waterproof

I went with just a short ram intake... less risk of water getting in, although i'm pretty sure a fine mist might penetrate

Also, you said stock rubber pipe... you don't mean the flexible stuff do you? If you post some pics it may help

Pretty much, there are orange gaskets around the two ports on the back of it and the rest seems to be one solid casting plus a plate that looks like it sealed pretty good.

The rubber flex intake elbow that the maf sensor is mounted in, well I cut that at that first rib closest to my intake so a 4" pipe would fit tight... Might sound redneck but it fit great, I didn't have to worry about making a new mount for the maf, and it actually looks good... I'll take some pics tomorrow.
