01' Maxima Exhaust/Intake Suggestions?

At the moment, My 2001 Max (5 speed manual) is bone stock other than some HID's, I am looking to put a full catback exhaust system and an intake on it, any suggestions for some not-too-ricey sounding catbacks*but still loud* and the same goes for the intake or any other suggestions you guys might have. I am pretty open to it!

In my personal experience cattman and stillen make the nicest sounding systems. i got my cattman for my 2k2 for $600 and it was pretty easy to install, fitment was perfect. the stillen i had on my 95 maxima and it also sounded great, but was a little pricey. as far as intakes, an apexi power intake is good, berk is a popular one, to be honest though an intake is an intake, it just depends really if you want a coldair or a warm air. ustavoid intakes that use foam or paper filters because they havea tendency to mess up the cars MAFS.

Well, i've seen the el cheapo intakes, but as long as the filter isn't paper or foam then it should be set right?*like the sound won't really make any difference or the performance won't?*

And, the same goes for the exhaust, 600 bucks is alittle much for me to spend on it. I probally got about 1/3 as much to spend, and I can come to terms with something that's cheaper, as long as it's loud and does it's job performance wise. Also, this may sound dumb, but would it better to get a full catback or go y-pipe and muffler tip?
