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

[mike.bmw]

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.

Hoping to have that answer today! Will let you know!

Add me to the list for 325i please.
Anyone knows if Mtech setup will fit late model cutout similar how OEM angled muffler fits?
I'm definitely getting on this deal....
just wondering if I should go Mtech route for more of OEM look and if I ever end up with Mtech down the road.

Thank you

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.

I will be able to answer the pipe diameter question, but I won't be able to answer the question regarding the specific bumper.

Hello Mike!

Please sign me up for a 325i exhaust. Could I please get angled tips? Thank you!

2 more days left on this. Let’s push it to 20% off. I guess we need 15 total orders for that? There are a lot more than that on the list already. Cmon people, go through with your sign ups.

Thanks Mike. This resolved my worries about the tips being too short. I just placed my order request and referenced the group buy. Please add me to the list.

You can request a mtech specific version. The mtech requires longer tips and they area angled towards the drivers side of the car more. The standard 325i version will not fit the mtech bumper. The other way around will likely look pretty odd if the tips do make it through the valance cutout. They will be extra long and not centered.
