318iS Stromung Catback Group Buy 2015

Here is the exhaust out of the box.

If your cat is bad you can just weld in the universal magnaflow cat section. Don't need the whole system from header. I couldn't pass emissions so I had to replace mine. Paid $50 for shop to weld it in.

I needed the whole system because the exhaust system that came in the car was welded front to back, so I had nothing to bolt the cat-back to. It was also full of leaks I'd have to have fixed, and just didn't fit the car as tight as I'd like. It was easier/faster to buy the whole system than to have my existing system hacked up and rewelded, and now I can bolt up systems designed for the car without modifications.

I hope. I still haven't bolted it up yet.

I got this: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

Hopefully I'll bolt it all up tomorrow. I'll try to remember to post back to let you know if I had any issues or not.

I was in the previous GB. It seems like it took forever to get it but, it was worth the wait.

Very happy with mine. Good throaty sound. I love listening to it. The radio rarely comes on. You will see! Enjoy!

Hey Ocell, what magnaflow cat section did you use?

[Ocell]

I needed them because the system that came on my car when I bought it was welded from the header back.

Part numbers are:

bolt 18301728074
spring 11761716668
nut 11621711954

You'll need two of each.

[CB-M3]

aah so we need spring bolts too? p/n for bluntech?

They're off on Fridays - you should expect to hear from Scott early next week hopefully.

[Merlin8]

I haven't heard anything yet either

The last list ended at dtm@heart. Looking at time of posts and when I received PM's, looks like the list of folks who didn't make the original list are:

1. 240trainee
2. johnwoo
3. Merlin8
4. SlickAlpinweiss (? are you still in?)

Scott told me he's waiting on 2 people to pay from the original group. And that he has 4 systems left over. 240trainee has already sent me his name, address, and phone number, but if you haven't and want to get in, send that info to me and I'll forward it to Scott.

Hopefully I hear from him!!!

Mine came in. I am stupid anxious to get it bolted up, but unfortunately my car's all taken apart right now.

Plugged it all together with the Magnaflow cat section I also got as a sanity check. This is my first time dealing with exhaust, so I didn't realize I needed the springs and bolts to bolt up the flange between the cat and the muffler section. Thankfully BluntTech is coming to the rescue and getting me the hardware fast.

Here's a pic of me playing Legos in the living room. Cat for scale.

Are the new hangers and hardware necessary? It's like $65 for new hardware.

No, if yours are in good shape you could use them. I would replace the donuts though unless you recently put them on.

[Merlin8]

You have a $400 cat back and $65 is too steep? Why not just use your current hardware?
