I recently got a 1990 560sel (california version 70k miles) The car runs strong, but im curious as to what can best be done to mimic the euro (tri y) exhaust. Is there a way to get close to ECE power numbers still keeping a high flow cat of some sort?. The budget Im targeting for this project is 1500-2000 including install. Is it possible to get close to the ECE power levels for this price? (btw. because of living in MI, emissions testing is not a concern, but I would like to avoid excessive exhaust drone)

TRY-Y's or AMG headers with down pipes are rare and pricey. The ECE engine not only had different headers, but different cams, higher compression pistons, just to name a few.
MB indie jhodg5ck aka Jonathan has taken apart several of these engines in his shop, and is still not sure what all the differences are.
The 'drone' is more due to removed resonators than anything else IMO.
Some members have installed TRY-Y's with low loss magnaflow cats, and hush puppy resonators.
Check the 'Welcome to the Forum' announcement / tutorial on top and search the forum archive for 'exhaust system' et al.
If I remember correctly, 48hp dyno chart showed a 29 hp gain with try-y's, low resistance magnaflow cats, and hush puppy resonators.
Cheers

Thanks. based on that, Ill probably just wait for another set of the tri-y headers/downpipes to show up on here or german ebay..and not worry about the rest of the ece stuff. If I could get close to that 29hp gain that would be fine w/ me (also going to check that other forum). Alternatively to the original route, is there a good known source that will durplicate the tri-y headers from a picture or diagram?. (dont want to necessarily go to a random exhaust shop)

pm 48hp. he may still have a set of the AMG-spec headers and downpipes.

search the forum, there are pics and write-ups on these headers.

they are quite nice. good luck. definitely worth it if you can get them

Based on the research I've done (with significant help from Benzworld) it has become clear that the best (and perhaps only?) effective way to increase performance keeping "German sound" is with tri-y or AMG headers& downpipes. What other parts (mufflers, cats, resonators etc) would you guys recommend for a complete setup (starting with California spec exhaust 560sel)? Thanks in advance

AMG Camshafts with solid lifters, but only after having upgraded to tri-Ys and better fliwing exhaust line. To get more mixture in you have to make sure it gets out first.

As a FYI, I have a real set of AMG headers up on ebay at the moment... I priced them fairly to what the replica headers sold for. They're not as pretty and shiny as the replicas but definitely do what they're supposed to:)

I've come across this company called Elbe Engineering in Estonia that apparently produces performance headers and downpipes for the 126

Elbe Engineering - Headers

I'm tempted to give them a try. Price to the US incl. shipping should run somewhere in the vicinity of 1700 USD.

I have no affiliation with this outfit whatsoever, and YMMV.

500sel to 500sel engine swap

I know this is going to bring grate debate but the idea I am going on here is there is no substute for cubic inches. my car is a euro 1985 500sel the engine came from a US 560sel, now what's has spurred the swap is the 5.0 just does not make the power I want and it has head gaskets that are starting to leak, the thing I forgot to do is take the cars computer from the downer car. this car is my daily driver makes a 20 mile commute every day

So i work in a grocery store in a small town where i drive my '83 300SD. this guy comes through my line at the checkstand and tells me that if i put a straightpipe on my exhaust and disable this somethin-or-other thing that i'll get more power. this guy is for sure a tweeker and i don't want his help but does anyone know where i can get turbodiesel specific performance information?... seems easier if this forum had a diesel specific board.

No need to pay that much, IMHO. They're not that hard to find on line.

I'm not sure if you've looked at it but the ALDA is one point you can adjust the amount of incoming fuel. It's tied into the over boost control. First start with plumbing a boost gauge to see where you are to start with. It sounds like NathanD has a great start on performance tuning his SD.

Kevin Casillas you are right about there's no substitute for displacement. I would love to swap a 560 into my 420. Do you have the dual snorkel air cleaner assembly? It's a shame these cars came along during a time in the US when emissions tuning was still being worked out. The US market missed out on the higher output motors
