Yep, similar to my experience. The product is not properly finished ready for install as you get them. There is quite a bit of reworking required to bring them up to a suitable condition depending on the extent of your own personal OCD before you go and install.ron wrote: ↑Mon Nov 12, 2018 11:21 am I bought a full M88 Fritz's system about 2 weeks ago.

I contacted Richard and he apologised and was going to have a stern word with his sub-contractor.

Re: m635 Exhaust options
brickwhite, you plan on reviving this thread after all of your engine work is complete
Still hoping to see this completed as well, not for me, but for a friend
He needs to replace everything from the headers back, as well
So I thought I'd bump this one up

Re: m635 Exhaust options
If anyone is interested, here are some pics of mine. Supersprint straight pipes back from the stock headers to Supersprint resonator and Stebro muffler.

Re: m635 Exhaust options
Thought I better get these (German/Chinese/whatever) euro headers on while I have access and the transmission is out.
remember these.. They were scratch free...
Oh Man this was a project... Hardest thing so far. took about 6 hrs or more.
I read where others put the two header pipes together and was able to fit them from the bottom.... I had no luck with that.
So I tried just the front one.... NOPE
Then just the rear one.. . NOPE
So I ended up installing the rear pipe and then lifting the engine with the Cherry picker about 5 inches to fit the front while both were not on the studs.
Then your 24 copper 9mm nuts some you can get to with at 1/4 ratchet some you cannot and have to use a small 9mm spanner wrench.
Have some 6mm flange nuts on hand just in case you bodge up the copper nuts.
Couple things that helped
- Cut the tabs between the pipes that were there for fabrication
- little anti-seize or lube on the studs.
- Make sure your stud threads are clean
- Cussing and swearing a lot.
- A second person to hold the pipe would have been nice.
I needed a cold one after that... it was to early no beer or whisky yet. Later
on to the rest of the exhaust once I get the transmission and driveshaft in

Re: m635 Exhaust options
I have the Euro/ebay headers installed now I'm laying out the full supersprint exhaust. But ran into a couple things.
They don't send you any exhaust Gaskets... They send you mounting bolts and clamps for the muffler but no gaskets.
WTF!
So I'll need some rubber hangers, Tri-bolt gaskets, and doughnut gaskets.
and the pipe seems to be 45mm so I'm assuming it's the 18111723541 doughnut gasket
but there is also a 47mm gasket.... hmm....

Re: m635 Exhaust options
Installing the supper sprint...
SuperSprint does not supply any gaskets and the bolts are limited..
This is what they give you minus the donut in the picture and I think I had used 3 bolts they included.
You will need....
- An assortment of Bolts m8x45,M8x65, or 70mm etc, stainless with copper nuts recommended.
I went the the local hardware store and bought some 5/16" stainless because they were 1/3 price of metric,these were which were too long and went back to my metric bolt bin and put in what I had..
Stainless bolts with copper nuts was one (only)set they supplied. Ideal usage but expensive.
- 1 Tribolt gasket 45/47mm opening, BMW PN - 18301723886
or
- 2 Sintered Iron donut gaskets I picked up at FLAPS (friendly local auto parts store) for $4.99 each. or BMW pn-18111178222
- 2 BMW muffler hangers (I had to order).... I hear for $2 more the BMW OE ones last twice as long....
Fitment...
Seems to fit pretty good the long pipes from the headers are labeled Left and Right.
My high tech temp pipe hangers.... Romex to the rescue

Re: m635 Exhaust options and Supersprint install
it's in... but need to tighten/straighten things up... it kind of leans toward the left.
The headers are really close to the steering center link. I don't have the heat shield and they are NLA, I'll try to make one.

Re: m635 Exhaust options and Supersprint install
Cool stuff Brickwhite, you certainly have a lot of $$ invested in your exhaust system. Looking forward to hearing your feedback on performance and sound.
I did my full (mandrel) stainless system from the Ireland Engineering headers all the way to the tailpipe inexpensively and was pleased how it all came out.

Re: m635 Exhaust options and Supersprint install
I'm a big fan of Supersprint; I have one of their systems on each of my cars. Don't know how many E24 owners are aware of it, but they supply this very nice "track pipe" setup that bolts right up to Euro downpipes on one end and the resonator on the other. I have one on my E24 and am also ordering one for my E28. "For off-road use only", of course.

Re: m635 Exhaust options and Supersprint install
I am surprised that you guys don't at least look at Billy Boat Tri Flo. Polished 2" stainless and made right here in AZ. I have been to the factory and have the product on my car as well. Interesting story. There was on my car when I bought it. The resonators had been bottomed out and were pretty grungy. I asked them if they would refresh the system and they said yes so I brought the whole thing to them. After a few back and forths starting at $250 and ending at $375 after I pissed them off a few times by calling them regularly to see if it was ready, which I went along with, when I went to pick it up, after waiting several months, they had given me a complete new system. I would say that says it all.To be candid, it's almost to pretty to use!!

Re: m635 Exhaust options and Supersprint install
Years ago when I was shopping for an exhaust system for my E24, I looked into Billy Boat; their systems do look impressive and very well made. I also like the idea of supporting an American company that produces quality products. I don't recall ever driving a car with a BB, but the only real complaint I've heard about them is that they're quite loud and give off a resonance at certain RPM. If you prefer your car louder, I suppose that would be fine; however I suspect some users feel they're a bit too loud and that's why they pop up for sale every now and then. I ended up buying a Supersprint for my E24 and have always liked the refined sound it delivers, without being overly loud or obnoxious. I also like the apparent quality and the fact that I never had a fitment problem with either of the two systems (E24 and E28) I've installed.

Re: m635 Exhaust options and Supersprint install
I bought a set of new BB headers and exhaust on another car and was impressed with their quality, the price is fair is well.

Erm, is it just me, or has the M635CSi (M88) option disappeared from the Supersprint website?
I can only see the 628/635 (M30) options...….

Re: m635 Exhaust options and Supersprint install
Bert, one word, glasspacksI am surprised that you guys don't at least look at Billy Boat Tri Flo
Or is that supposed to be 2 words
Larry is spot on, even though he has not actually been in a 6er with a BB system installed
I went to great lengths to "tune" my BB system to something that was finally tolerable, without the drone of those crappy glass packs
All that's left now from the original system is the rear muffler section
Sorry to say, but if that's what you have and have yet to actually drive your 6er and get some time behind the wheel, you may be in for a surprise, and not a good one
Brick, indeed, nice work, been anxiously waiting for the completion of your project, so that I can forward on to lurker ONEBADM

Re: m635 Exhaust options and Supersprint install
I drove it with them before tearing the car down and never noticed it. Could be I only drove it a few times before tearing it down and was too excited to pay attention or could be my hearing aids aren't tuned to that frequency. However I bought the car from a friend and had been in it more than a few times but never on extended drives and never was bothered by it. Maybe from my old hot rod days when if you didn't have glass packs you were not one of the "guys' Or even prior to that when it was true hot rods with flat head ford V8s and straight pipes. The picture is of me in an old Miller I bought for $200 with a loaded Merc flat head. I used to "borrow" the plates off my mother's car and go "riding' in it. Unfortunately almost every cop in town new my father. When I went off to school I came home for vacation and guess what wasn't there. I would be counting stacks of money now if I had that car today. That was one of many that followed Those exhaust systems are probably why my hearing became fubarred

Re: m635 Exhaust options and Supersprint install
Uh, yeah, looking at where that exhaust exited, i bet your hearing is a bit off
The drone is frequency and RPM specific, for me it was around 2K to 2200 RPM, most noticeable when just tooling around town
Sure, if you zoom up through the rev range, you could pass though without a hitch
But it's also more of a "feel", as anything in the interior that wasn't absolutely nailed down, would buzz
I have also heard that B&B has gone to great lengths to try and calm things down, but at the muffler end of the business, not where a resonator should be
Just went on their website, and it appears that they are still using glass packs
Well, you'll know soon enough, right
Brick, sorry about stealing your thread, but worth discussing
