Are they separate issues or happen at same time? Need more info about clicking. My car makes a little noise if I am going very slow and turn the wheels all the way.

ticking could very well be wastegate rattle. it's a known issue with the n54.

the noise is the power steering system, my car does it too. perfectly normal, i believe.

power steering whine is very normal, that being said, if you're making it wine, you're being hard on it.

turn your steering all the way till it stops, then back off a quarter turn so it doesn't do that. it's not exactly nice on the systems to crank them full stop.

on that subject, i'd also like to add that flushing your power steering fluid around 30-40k miles is HIGHLY recommended. bmw won't pay for it, since they call the power steering fluid a "lifetime fill." BUT, i was appalled at how disgusting the fluid was on my car after around 40k miles.

i looked for the thread i remember reading an n55 cp-e exhaust review in. i believe it's been deleted, however. it was ar design's old group buy for this exhaust. at least one person is running it on the n55, he had great things to say about it, too. sorry i couldn't find that thread, like i said i think it's been deleted now.

bottom line- cp-e is one of the best exhausts overall on the market. great power gains, exotic exhaust note, subtle styling, etc etc etc. i'm almost pulled the trigger on buying one a few times for my car

Hey Bryce, is this true for n54 also? Is it cat back system? I have heard good things about the maddad and a few I can't remember.

Does changing the midpipe to "high flow" cats on stock downpipe and axleback gets you any gains and sound? How much different would I be getting?

yea, the same can be said for the n54. it's probably the top or one of the top two exhausts for the n54/n55 CURRENTLY on the market for power gains, sound, etc.

it's a modular exhaust, so you can get the downpipe-back section, just the axle back, or just the midpipes. cp-e makes catless downpipes, as well, so you could theoretically have a complete turbo-back exhaust from cp-e. i love the way it sounds personally

not much power to be had there. catless downpipes is the biggest power gainer as far as exhaust modifications. i run ar design catless downpipes with the stock exhaust, sounds nice and subtle and i'm not losing much power from the secondary cats or muffler. one of these days i'll probably buy a dp-back exhaust, mostly for the sound though. like i said, the biggest restriction is the stock downpipes. get some catless dp's and enjoy the quicker turbo spool up, higher boost capabilities, and the intoxicating "swoosh" sounds

Running full catless set up. Just recently swapped out my AR Catted dp's for Macht Schnell catless. Instant power improvement, didnt expect to notice much difference but overall power is MUCH improved. The cats, even race cats, restrict a lot. sound overall wasnt changed too much, a little more volume but the biggest difference was the power.

GO CATLESS!!!

I am inpatient too! Just got off the phone with HPF...part is ready for fabrication but stupid delays in BOV stuff and E46 M3 delays since they are spending cash load on some other products. It cost roughly $11K to get the prototype to fabrication to build off of...but it is still happening so lets be patient together cause it is going to be SICK!

GO CATLESS!!!
I remember talking to you about this some time ago. Did you happen to do any dynos? How noticeable are the gains, have you been able to test them out by any chance? I'm considering dp's at some point but unsure to go catted or catless. If there are noticeable more gains for catless I'll go that route.

I understand but I just want a date or a time-frame. I feel like we've been left out of the loop for a while now. I have friends who tell me not to wait for HPF due to a history of failing to meet time requirements but they do assure me their quality is top notch. I'm patient but I don't want this to stretch out for months either especially when I'm expecting the parts to be released within a few days.

Do you have any more info regarding the BOV application? Do you know if HPF can weld on a specific BOV to their charge pipe, eg the HKS? I believe they're using the Synapse.

Do you know any more info about the intercooler piping? Is it wider in diameter? I'd probably consider getting the HPF fmic with the silicone coupler version connections if it works with the stock piping until the rest of the kit comes out.

Yea, agree on the catless, but it smell really bad, and could have a pull over here in Canada if you drive a new car with black smoke coming out from your exhaust!

Nice detailed info tho. Keep it up!

I'm figuring on replacing the secondary cats with high flow, but bigger ones then stock so that they will still be effective, but at least a little better flowing.

i will be doing catless DPs though.

If your engine is quite warm, you really shouldn't have to worry about the emissions with a high flow secondary or even the stock secondary cats.

at least that's what i've heard.

and if they probe your exhaust to see if you have a cat, at least there will be something there if you leave the secondarys.

I ran catless on my subaru for a couple of years, the exhaust colour wasn't too bad. As far as the smell goes, it won't be as bad as an old muscle car, but not far off from it the one thing the police will notice is flames out the back without the cats installed. And with no cats and big power, you should expect a lot of flames.

Are the police still pushing the side of the road checks around markham? it seems to have died down pretty much to nothing around here. at least i don't hear about it anymore, but i try to avoid the standard tuner forums for the local towns.

oh, and one more thought.... catless and windows down, over time builds residue on your interior, so just be aware of more deep cleaning of the car. And maybe even your lungs......

but those are just side effects of power

^agreed, great points mineo and the1 about going catless. i'll eventually get a dp-back exhuast, catless. i still like the quiet and unassuming position my car makes with the stock exhaust though. i beat my friend's roush 427r the other day from a roll, all while being relatively quiet

I was considering getting electronic valves installed in the exhaust. at the touch of a button, bypass the rear cats and muffler :P

or half open so it's quieter.

We'll see what the future holds though.

that'd be interesting. i've seen those electric valves before on other car platforms. the only thing i worry about is that would basically be right off the downpipes. i've read horror stories of people who drive around open-downpipes on the n54. WAY too loud basically

Spoke with JP/Dave/Chris at HPF today, here is an official update for those folks out there:

Mineo77: Do you know if HPF can weld on a specific BOV to their charge pipe, eg the HKS?

HPF: <Still in the development phase. Synapse is the proposed BOV>

Mineo77: Do you know any more info about the intercooler piping? Is it wider in diameter?

HPF: <3" piping will be used. This is slightly larger and higher flowing than the stock N54 piping>

So keep your pants on, a release date will come...and we all know HPF rep of top-notch products and service!
