Stromung Exhaust
 

Hi all,

I would like to know everyone's opinion on the Stromung Exhaust, installed on a 318ti? I am thinking about upgrading my exhaust to a Stromung in the near future, but want opinions from those who currently have them installed. I have read as many threads as I can find relevant to Stromung exhausts on this forum, but I would like just a little more information. I have also watched many clips of Stromung exhausts in action, but I've read that videos don't do this exhaust justice.

For example, how would you describe the tone of the exhaust? Does it give a noticeable performance boost? Does the Stromung have any issues with installing on a 318ti/316i Base model which has the standard rear bumper as opposed to the M-Tech rear bumper shown on Understeer's website? Is their noticeable cabin noise from the exhaust?

I've looked at these at Understeer.com, and I was unsure if they ship internationally or not? I did send them an email last week, but I'm yet to receive a reply. Does anybody have any idea on how much shipping would cost to Australia?

I will be upgrading from a custom sports exhaust, which personally, sounds a little too stock. I want something with a nicer, louder tone, and so far, the Stromung is my first preference.

Nothing other than a blower or turbo makes a noticeable gain on these cars. Well, there is a motor swap....

Fit isn't an issue on a non sport bumper. There is cabin noise, and if you have the seats down or the cargo tray out it's really bad. (without the resonator)

Most people have a resonator installed on them and are really happy. I really like mine, it sounds great, deep mean idle tone, and that's with the resonator from the stock exhaust on it.

Thanks :) I'm definitely leaning towards the Stromung. Performance isn't all that essential, but the nice tone is.

Did you buy yours from Understeer?

Is stromung even making them anymore? When we did the group buy a few years ago I thought the shop said they were getting rid of the jig since sales were so low..

I got mine used from a fellow forum member.

I hope they haven't discontinued the exhaust! It appears that they're still for sale on Stromung's site, and understeer still have the exhaust listed.

Has anyone bought a new Stromung recently from either of these sites?

I've got one, I think it sounds pretty good without the resonator but I usually have my radio up so I don't really hear it. it's one of the louder ones you can get that still sounds decent

I'm definitely leaning towards buying one! Where did you purchase yours? Do you know where they're still available?

Perhaps I'm not very patient, but I'm slightly unhappy with Understeer's customer service. I've emailed them, and have yet to have received an email with a quote for the exhaust and shipping to Australia.

I want to give them my money!!

I bought mine used from a member here

Thanks TiFreak.

Scott from Stromung got back to me earlier. He said they can build me a exhaust with a slip connector instead of the full system, which would reduce shipping by half.

Would I still receieve the same experience with this Stromung exhaust like I would have with the full system? Eg. Exhaust note/tone?

what exactly would they be sending you? if it's just the muffler you would have to remove the factory resonator to get it to the same tone as the full system. you'd probably have to have an exhaust shop do that since the resonator has a bend in it

I've quoted this directly from the email they sent me;

What do you think? I wish I knew a little more in this area.

sorry, didn't get a chance to get on yesterday

sounds like they'd be sending you the whole catback but split in half so it will fit in a smaller box, that shouldn't sound any different than the regular one-piece system. it wouldn't be much more work to install either

No worries mate!

Yeah I received a quote from Scott at Stromung, and the price of the exhaust is still the same. Hence, I'd assume the exhaust is exactly as you described.

I just processed payment to Stromung, so I'm looking forward to finally installing a Stromung on my compact. Shipping was pretty damn expensive to get to Australia, but there's nothing I could do to avoid that.

I'd also like to note the great customer service from Scott at Stromung. He was very helpful, and even gave me a small discount for the exhaust, because of the expensive shipping. I'd definitely recommend buying from them.

Thanks to everyone for your help. I'll be sure to post a sound clip once it's installed.

I'm guessing he means that they will ship it just like supersprint exhaust are done. The muffler will have a short pipe with a flared end, then the piping side that connects up to the cat is seperate and is also flared to mate up to the muffler box. That will reduce the sq.ft. required for the box and reduce shipping costs. The muffler itself is kind of light, so you end up paying by the size of the box, not the weight if everything is welded together.

Yeah I think that is what Scott was trying to achieve.

I'm just letting you know my exhaust arrived! It was packaged really well, and the finish of the exhaust is fantastic.

I've booked my car in with my local exhaust shop to get it installed tomorrow :D

I had my Stromung installed today. I ran into a couple of issues though.

The cat must be positioned slightly towards the rear of the car on the Australian 316i, in comparison to the 318ti. The muffler fits fine, but the piping that connects the muffler to the cat was too long.

My muffler shop had to trim the piping down, and install a replacent flange, so it would fit in between the cat and the muffler. Other than that small issue, installation went great.

However I am a little disappointed with the exhaust tone. It seems a little quiet/similar to my old sports exhaust. I can tell the difference when the revs are higher, but I expected a more noticeable difference in the overall tone. Will the tone change once the exhaust is broken in?

I'm very happy with the look of the stromung though. It looks great!

Did cutting the flange and shortening the pipe, and then installing a new flange on the shorter pipe have any effect on the tone? It doesn't really matter because it was either that, or no stromung ;) but I'm just curious.

Where can i find a full exhaust Stromung for my 98ti?

I only see their muffler...please reply. Thanks!

I believe the Stromung is only a catback system.

In general muffler sound and tone change a bit with breaking in. Stromung's? I don't know. I would not think that the new flange has anything to do with the sound. Cheers, John
