My Two Plus’s should be shipping in a few days.

[type-dRew]

Thats a solid deal

[HKD126]

It makes the RB Two’s $1600 when factoring in the $300 inlets and $200 install kit. $1800 for the Two Plus’s. Solid indeed for an everyday price.

Seems like the DA turbos aren’t really a budget option anymore when you factor in the new oil/coolant line and the exhaust you need to buy for them... Regardless. I’m still excited to see everyone’s results with them.

Different platforms within the n54 powered sphere have different exhausts. Some are more restrictive than others. E90 is not restrictive for most end uses; changing out an exhaust at about the 500 whp level will net you 10-15 real world whp that starts being visible around 4.5k on up (not a deal breaker). It's a minor difference. I understand the 1 series is more restrictive.

How about the FACT that its a pig of an exhaust with two separate super heavy mufflers and a dual pipe design for most of the length of the car unnecessarily. Seriously, the stock exhaust weighs A LOT. Ever tried to lower the whole exhaust section from DP's back by yourself? I do not remember exactly how much it weighed but switching to VRSF single shot 3.5 it flows more exhaust gases and shaved off over 40lbs from the car. Weight matters and that is more than enough reason. Throw in the fact it has secondary cats and I would say there is no good reason to keep it unless you just cant afford an upgrade. Btw, what about the sound? Does no one care about the sound your car makes?!?! jesus. My car had a brand new exhaust catless DPs to tips before I even started thinking about buying turbos. You gotta pay to play

My car sounds godly with stock exhaust a part from catless DPs and second cats replaced with resonators. And nice exhaust tips.

I own a pig of an xdrive and weigh 370lbs myself. Weight is an issue regardless. lol, i dont care how much the stock exhaust weighs, theres plenty of other places to cut weight that wont make anything louder or cost me money.

There are lighter engine options as well, that n54 is a big pig hanging over the front axle with all its turbos and plumbing. Ill slam a NA k20 in there to shave 300lbs.

I meant to say mine mb

Well I have to say I have IS exhaust to which is more like the M performance, so I guess it's technically not stock stock but yeah. Never with this car did I feel the need to get a new catback exhaust.

Those pictures are bullshit. That's not how you use a caliper. He's not even measuring the outsides of the pipes, he's only measuring what he wants to measure.

Ohhhh yessir agreed then. The m perf and is cat backs on N54 sound much much better than normal stock. Personally I have a rwd N54 coupe so i want to save weight wherever possible and i am a huge stickler for echaust note haha even my E90 N52 has factory M performance exhaust with secondary deletes and afe catted headers and car sounds amazing to me, raspy bmw straight six sound ugh i love it but its not for everyone

Was thinking exactly the same thing but didnt give enough shits to actually mention it lol. props

I'm not here to throw gas on a fire that gets away from the topic, DW turbos, and the intention of this thread.

I have to admit that for the first time in 20 years of performance enthusiasm, I have never seen people defend keeping a stock exhaust on a car. Air in and exhaust out has always been priority 1 over every build I have followed since the hot rod days. Intake, headers, exhaust. In the Supra and GT-R world I followed, it seemed to be 4" exhaust or go home.

I used to be a powerplant engineer, so I know why I will be yanking out the exhaust and putting in a straight pipe system. I won't run what I am building with the stock exhaust. Whether or not Dynamic Autoworx had it as part of their warranty or not.

I'm not foolish though to piss away a 3 year warranty. I have no right to yell at a manufacturer when they don't replace something, under warranty, when I knew full well what the warranty stipulations were on day 1.

Speaking on the VSRF 3.5", I do really like how they basically allow you to have two ways to terminate/interchange their system. You can pull off the street muffler and drop on the race pipe ends in just a few minutes. Perfect for those who track and street their cars. About $1,000 if you get both options. That's a steal.

The fact that it drops 40lbs is a bonus, adding HP is a bonus, but honestly having a 100% free flowing exhaust is what matters to me.

On a side note, who sells the best turbocharger install kit?

Not looking for the cheapest but the one that comes with the most of what is needed paired with quality.

My Eisenmann Race exhaust sounds pretty mean.

[type-dRew]

Yeah i like upgrading exhausts, but when you have 2 2.3 inch pipes(4.6inches total) and swap it for a single 3.5inch pipe. You dont have more total flow. I dont see the benefit aside from losing the cats and resonator, which can be done with the stock system also.

Imagine doing a twin turbo 5.0 mustang and running 4 inch downpipes into a single 4 inch exhaust. Does it make sense on that application? No? So why do it here.

Ill upgrade the exhaust when a reasonably priced true dual 3inch system is available. Closest now is an AFE system for $1200 @ 2.75inch, which is pretty damn good but i cant justify that price and again, the cars just dont respond to upgraded exhausts as much as other stuff. Im a big advocate for the best exhaust is no exhaust on a turbo car, but these cars just dont seem to gain much from running even open downpipes as much as id think with big power.

[NoGuru]

Here is my IS with no cats and Vibrant resonators where the secondary cats were. Still on the stock turbos at the time.

just use OEM parts.

what's your mileage on the motor? noticed you are swapping bearings out in earlier posts.

[KnighTT]

160k. Hence the reason behind replacing a lot of peace of mind parts.

I'm going to be running a few tests on compression this weekend to see if I have any reason to yank it and do a full rebuild over the winter.

My situation is a bit different than most. This is the weekend fun car, not meant to be a daily driver, but it is mostly the basis of actually getting into Motorsports. The car will only stay street legal for another year or two and then it will be dedicated for track use mostly.
