Vorsteiner Titanium Exhaust Install and Preliminary Impressions

I installed this exhaust with a buddy today. We put the car on ramps and rolled under it. Obviously, car on a lift is a much better approach, but didn't have access. It took us about 2.5 hours--mainly because of a misalignment issue. Some observations on the install:

1. Stock exhaust is a tank part. You can look at the numbers on a piece of paper all you want; you don't realize how heavy that fucker is until it falls on your chest. I really can't believe how bulky the thing is, and have a hard time understanding why it was designed the way it is. If air flow under the car was a consideration, I am sure there are other ways to manage that without sticking such a huge muffler on there. Anyway, I'll have to mull over this one...

2. The rubber supports the hangers slip into are a bitch to deal with on the stock system since the stock hangers has lips over the hangers that really lock things into place. You have two options. You try to pry the stock exhaust from those rubber supports while everything is bolted on, or you simply unbolt the supports and pry things out where there is more space. We did the latter since the car was on ramps, and I am glad we did that as it was much easier to decouple things outside.

3. The right titanium pipe lined up well, but the left one didn't and was contacting the subframe right after the diff. I was concerned it would rattle there and crack. I was finally able to adjust for this by adding spacers to one of the back hangers, and got some clearance.

4. We weighed the stock monstrosity on a general purpose scale, and it was 58lbs+. It was so cool to be able to lift the entire titatinium piece by myself and place it under the car.

5. I bet one can do away with at least one of the hanger systems since the titanium system is much lighter, but I ended up connecting everything back anyway.

6. I ran the car without either muffler on, and it sounds really cool in person.

Some prelimenary observations on the sound after 40 minutes of driving (I opened it up just a couple of times):

1. The idle when you stand outside the car is really good. Nice louder and slightly bass tone.

2. It is louder inside as well, again with a slightly bass tone, and it is just right for me. It is not too loud, which is something I was concerned with since this is my DD. The stock system was definitely too calm <4000 rpms. This exhausts solves that problem nicely. Bingo.

3. Once you are over 4500 rpms, it sounds fairly similar to the stock system as you start hearing the intake and all that, but I can't tell how it is from the outside. It's still louder, but it doesn't sound that much louder than stock.

4. There is no drone that I could identify. I messed with several gears and rpms to listen for this.

5. A downside is that the louder tone now surprasses the intake sound at lower rpms. There was not much of an intake sound with the stock filter at that range, but I started hearing it after installing an aftermarket filter. Now, I can't hear it again. So, now an intake mod or what to get intake sound back?

In conclusion, this was a great mod at a pretty good price. My main goal was to make the car a little louder down low and save a bunch of weight (~40lbs). Both have been accomplished. I haven't dynoed the car or anything, but Vorsteiner also claims some power gains. If they are there, fine. If not, not a big deal. I am rather happy overall.

Thanks Monsta!

You might want to make sure your connecting pipes are not contacting the subframe just in case.

I won't be posting vids, so yours will do nicely. I will post some pics so that folks can see the tips on Jerez if they are interested.

yes I knew about the issue since I helped the guy install the exhaust, I'm sorry I neglected to write about it in my post w/ a busy work schedule & planning for my trip, we also fixed this issue w/ a spacer and a lil tweaking here and there & just like you it was on the left side connecting pipe...

once I get back I'll post some more vids for everyones enjoyment

I'm on a debate to switching my exhaust w/Vorsteiner. I love my AA exhaust system and definitely nothing wrong wit it but its a bit too loud for me. I've heard the Monsta's and once again after the Angel Eye that he had LOL... the system was incredible. So my question is that when u guys installed the system, was it very difficult? or is it just some minor fitment issue? Thanks in advance~!

lol Dave your buggin out....I think your problem is not that the AA is too loud but that you have the Xpipe installed also, those X pipes would even make the Stock exhaust sound much louder...

Yes the exhaust is very very simple to install and only needs minor tweaking to get it to fit right an extra set of hands is a must, also as you can see even w/ the car on ramps it could be installed

Haha sorry Bill, didn't mean to do that but anywayz. I've thought about that too that having a x-pipe but I don't think it'll go as loud as w/Vorsteiner, after hearing urs. Additionally, I like that burnt TIPS Thanks for the info.

Lucid, thanks for the review.

One question though... it appears that none of the aftermarket connecting pipes have the OE heat shields to reduce radiation from the pipes to the rear output shafts/rubber coverings. Do you think this may cause premature wear on the shafts?

Congrats Lucid! Can't wait for some pics. I think I decided this is the exhaust for me.

I must say I noticed that the connecting pipes get pretty close to the diff and the axles. And, yes none of the aftermarket systems have the partial heat shield at that point. It is possible that there might be some undesirable effects, but I have chosen to take that risk. I do question Vorsteiner's take on the straight connecting pipes on this system. I think they had an angled design at least to avoid the diff in their prototype. Unfortunately, I don't think any of the aftermarket manufacturers have any real data on such issues, so this one's kind of where you cross your fingers and hope for the best. The weight savings and the subtle sound improvement were worth it for me.

lucid do you think it is possible to integrate the OE heat shields to the Vorsteiner pipes(in your case) or other aftermarket pipes ?

I bought 2 of these 1' Thermotec clamp on heatshields just to be on the safe side. I noticed that there was an aftermarket exhaust system being designed with the same exact clamp on heatshields.

Sweet, my thoughts are the factory muffler is the heavy anchor it is to maintain the BMW typical 50% weight distribution.
