Yep, very happy with it. Also, very unhappy they decided not to make the hood for our cars. I waited over 6 months for them to make one, but they decided against it. I'm going to wait until the Spring now, and probably get the Seibon one with the hump.

The Inside Performance pipes are closer together, giving it the E46M3/Z4M look. The sound is absolutely outstanding, it's honestly the first inline 6 BMW motor I'm proud to hear rev. My exhaust is straight through, and there is no droning at any rpm. Car is quite loud on a cold start, but dies down after about 10 seconds. At wot, the car has a high pitched wail. I am very, very happy with my exhaust purchase and highly recommend it to all.

One last thing, I must admit the setup does look a bit hokey without the diffusor. There is one big can, with a little pipe leading over to the other two tipes. However, you never see it with the diffusor on, so it's not an issue for me. As well, the amount of exhaust you see coming out of both pipes is almost identical. I've looked at the rear of the car on cold mornings, and I'd say about 55% comes out the driver's side pipes, while 45% comes out the passenger's side. It's VERY close. As well, the inside of the pipes are discoloring identically, so you don't have two dirty pipes and two clean pipes. Also please note, I've painted my setup with black BBQ paint. It doesn't come in this color.

Do you have any sound clips of this set up? If you do please post some.

Lets get this thread back on track.

Anyone have any movement on this?

My parts won't be here until another few weeks.

[1SER135]

I got all the parts for the exhaust already but wont be doing it until I get my DP's and intake/cooler aswell so I will be finishing mine by the second week of january (hopefully it doesn't take more then 2 days to do the whole lot)

I will be going from a completely stock car to FBO, M3 Parts and 1M exhaust with Hartge diffuser so should be a nice transformation

Wow that looks amazing!!

the left side of the exhaust is the most functional...doesnt the additional 2 pipes do nothing but add a small amount of exhaust release and just add a ton of weight?

[NORAGRETS]

you need a Y pipe from the mids to split to the two tips to really have a dramatic noise and exhaust effect...am I wrong?

[ilikebmxbikes]

Both venom and myself are doing this. Both should be done in a few weeks. From having all of the parts on hand and examining them vs the 1M ones all should fit up with the parts below. The total for the parts will be around $400-500ish. I dont have my price sheets on me. they will line up with the 135i rear bumper but you will need a custom diffuser.

1M Parts you need:
Battery Tray
Heat Shielding
Rear Bumper Support bar ( has exhaust hangars)
Exhaust hangar rubber (3X)
3X evaporation Canister hoses w/ connectors
1M style Exhaust

Man I am still waiting for my 135 to come in and this is like the first mod I would want to do. I have always loved the M setup on the exhaust and hate that the 1 series doesnt even have the dual split pipes like the 3 series. It feels unbalanced to me. Can't wait to see how this turns out.

Subscribed for sure to see the results.

what part is the 1m battery tray trim thing? i'm having trouble finding it

ED:51718051597 ?

what process is involved in relocating the battery though?

also, i've been looking for a photo of it for LITERALLY months now, can someone post up a pic? even of a stock 1m

I would say it is in the middle although i did not see that in person.
I guess we will see more and more 1M replicas

Below are parts diagrams with annotations to what you need to get 1M exhaust to fit on a 135i. Most of this info was accumulated by Venon and I's trial and errors and until the exhausts are actually on our cars (mine is being fitted now) this information is subject to change.

The battery tray relocates the evaporation canister to the side to allow room for the exhaust. This relocation requires different evaporation canister hoses and longer battery cables. These items will also need to be purchased to make this mod.

The 1M exhaust hangers despite not being in the photo diagram are located on the 1M rear bumper carrier.

I hope some of this information answers some of your questions and clears up some of the speculation.

if you know of anyone wanting to do this mod, I have an OEM 1M exhaust i'll sell them for reasonable price that will make this mod worthwhile.

What do you want for the 1m exhaust ? I want it.
