your talking about an exhaust right? Woudnt do it, course it gets annoying pretty quickly.. its for teenagers.. not for pornographers
i disagree. my car has a rather loud HKS cat-back with Invidia downpipe, and high flow catylitic converter (3" from the turbo on back) and i love it ;)
it sounds like a baby ferrari when it revs, and with the new computer tune i am running produces about 50 more wheel horsepower from the stock setup.
i don't think the bimmer would gain that much with just a new exhaust, turbo cars make bigger gains with better breathing over an N/A setup, but it will certainly make a nice difference.
if you don't want to go that deep, i would reccomend doing nothing at all.
car modification is about 1000 times more addictive than anything you could imagine.
i've come to terms with the fact that until my car is a lightweight, high powered time attack monster that can run under 60 seconds on tsukuba, i will never be happy.

With re to your exhaust, have you been in or heard a 540 with the exhaust you're interested in? Drone can get pretty annoying if you're more interested in having a luxobarge.
Also the performance gains will be minimal unless you combine that with a tune and a CAI. If it's sound you're after - get a nice cat back exhaust, will provide more power and a sweet note.

The Magnaflow's aren't as loud and obnoxious as some of the other brands out there. And they are actually one of the best flowing. (one of the worst being Flowmaster)
Your best bet would be going with a complete catback. Just make sure you get stainless or you will want to kick yourself in a couple years.
No doubt BMW has some restrictive exhaust on there to keep the noise down.
Modifying cars is like crack. Once you've added some performance, you want more. Case in point: What starts as a stock engine will soon be a horribly overpowered money pit, with far to much horsepower, and a great sound.
Stock? Sure. Reliable? Sure. 300hp? Sure.
Stock? No. Reliable? Slightly. 800hp? Yep.
And don't think you'll be content with 800hp either, because once you've had 800 for a while, it's just not as exciting as it used to be.

drone totally depends on the exhaust he gets. in my experience, if you buy a good quality exhaust, it's not going to be that obnoxious. my HKS has very little to no drone at highway speed, where as many other similar exhaust that i could have gotten for 1/3 the price that drive me nuts.
also, the CAI may not be necessary. every car has it's own mod path, and responds well to different things, but in most cases i have seen cold air intakes don't really do much good. he may be better off with a cone filter, or even a modified stock airbox.
i would really consider going headers back though for the exhaust. simply replacing just the muffler, or just the cats isn't going to do much good if the rest of the exhaust is still very restrictive.
remember, an exhaust is only as wide as it widest point.

Comparing exhaust noise on a turbo versus non turbo is real apples-oranges.

haha. cars are alot to learn than the particulars of this industry. there are several good bmw boards around that are an absolute wealth of information.
that's how i picked up about 50% of my knowledge about cars. the rest i have accumulated through practical experience.

yeah, but the basic principle of buying a good quality exhaust system to maximize flow and minimize drone, i think, remains the same.
Boss- Do yourself a favor and contact active auto workz in miami FL...they did a supercharger on my 3 series a few years ago and it was just sick. Dont do anything else, they will advise you. I cant recall a race I ever lost. Even with the 1200 shipping to FL from NY I wouldnt have changed a thing. Man I miss that car. GL with the mod'ing.

seriously i just wanted a little mod, my car is already sick with 285 horse power v8

I've never come across an engine that does respond well to CAI. Increasing airflow and the temp it is picked up makes mountains of difference.

Flowmasters aren't obnoxiously loud unless you go with 44 or higher. I went with 40 to be street legal. Thought I was replacing a Magnaflow system but it turned out to be some noname brand cheapie system with the pipes bent incorrectly up to the collectors. Barely cleared the headers and would bang up against the underside of the car if I hit a bump. Previous owner didn't know Magnaflow from Ram Air.

ok, shark injector, CAI and maybe pipes. all for under $1500, prolly add 60+ horse, but I really am guessing here. Not sure about Canada, but in the US thats a legal set up. OOh and it will sound sick, not rude, just a nice whistle/rumble.
I'm thinking of throwing on a Flowmaster super40 on my Jeep Wrangler this week
Check youtube or another tube site for sound clips with your car and exhaust first though or find someone else who has it...You may be highly disappointed.

Jyeah, find a decent shop too... that's come with recommendations from people in your local tuner/mod scene.
Don't want to go to a shop and have some asshole slap in 3" tubes, when 2" would give you the sound you want without performance losses or vice versa...
Exhaust is highly overlooked area of car performance unfortunately... not all just about sounds

I've never come across an engine that does respond well to CAI. Increasing airflow and the temp it is picked up makes mountains of difference.
depending on the design of the CAI, it can actually make it harder to get the air in to the engine. most of the ones i have seen increase the length of the pipe substantially and decrease the diameter, so that it can fit down in the fender.
it doesn't matter if the air you're pulling in near freezing, if it is harder to get it there, it's not going to help. the whole point is to make it easier to it to breath. imagine running a marathon, but only being able to breath through a straw with ice around it. doesn't sound very appealing, does it?
plus, it is not like there is going to be a substantial difference in air temps from the front of the engine compartment to the fender well for example. maybe 10 degrees. maybe.

i have no idea what your discussing ... i guess i gotta hit up bimmer forums more often

haha, yeah, there are plenty of good bimmer forums out there to read. you will be able to find the best path for you car with a little research.
engine basics are simple in theory. more fuel + more air = more combustion. more combustion means more power.
but the particulars of amounts and how easily the fuel and air get there are when it starts to become a little tricky. ideally you are pretty much looking for the most efficency you can attain. generally the easier the fuel and air get into the cylinder, and the easier exhaust gases are evacuated from the cylinder, the better. generally. ;)
