Strömung Catback Part 4! 318i/is and 325i/is (Jan 2, 2019)

[Sean S.]

So, can we get an angle cut to match the stock look on the 325i series muffler?

Add me for the 325is please! I just got a racing dynamics apron I don’t know if I would need the angle cut or not

I put together a quick playlist of the sounds my 318i makes in various situations. It's mostly stock M42 with a factory front section/header, a Mark D chip, and a 4.44 rear end. It's only cell video capture, so it's not absolutely accurate sound, but it is representative.

Appreciate it. I’ll take a listen. Thanks!

Confirmed add me if you guys are doing an angled version please

What does the slash cut look like described in the original post?
Money needed up front?

[Cakey]

Gotcha.

People w/ the stromung on the m42... what is your opinion on the sound?
I daily mine for the most part. YouTube makes it sound kind of raspy

Daily mine and its great.

Much more tame and natural than the Megaflow i had.

Its not in your face but does give it a nice OEM+ note.

I don't have any photos of it, but Scott has told me it's dual walled like the one on their website, just slash/angle cut. The tip still points in the same direction as the one on their website.

Gotcha. Understood

Making good progress! 8 for the 318i, 9 for the 325i!

I am in for my 325.

12 orders for the 325 system! Assuming everyone follows through the full discount for the 325 system has been achieved!

Still waiting for pictures of the mtech unit. Can you get those?

Id like to do a Stromung for my S54 swap 325is.

What are the tube sizes leading up to the muffler? Might need an E36/E46 model instead.

Sorry for the delay. Family caught a stomach bug over the weekend.

These are from Scott. He says, "These are pics of when we did the fit so the tips are unfinished." So basically these just show the fitment, but don't show the final tip style, which I don't have pictures of.
