doing it the right way( EXHAUST)

[pinoyk20]

hi guys! im planin on going back to the stock exhaust pipe diameter byretunring my stock exhaust pipe. my question is is it OK to install a 2.5inch diameter X pipe with a lil bit 2.5 diamter straight pipe to connect to the stock 2.25 exhaust diameter the reason for the use of 2.5 as a connectort pipe to the X pipe and stock 2.25 is that we dont have a 2.25 stainlesssteel pipe here in our country, pipes only comes with 2, 2.5 and 3 inch but no 2.25. and also can i use a 2.5 race resonator then connect it on the 2.25 stock piping? thanks im hoping to get more tq from the car. thanks

Longest sentence ever...

Man just do it, let us know how it goes... if your going back to stock I don't see how that could possibly harm your car.

the reason why i ask is to make sure that the things im gonna do are corret. pls lets make this a healthy forum. there are experts in here that are very glad to help so if you have nothing polite says pls respect the others who are asking.

I just put 2.5" high flow secondary cats, 2.5" x-pipe and used 2.5" stainless pipe to get it all together and put it on the stock pipes so you should be perfectly fine doing it that way. Check out my exhaust thread for pics if you have concerns.

it should be ok.

but why not reuse the stock exhaust, and just add a x-pipe in place of the resonator, using the stock piping? i would think it would be less work and the same result.

either way it should be fine.

I just don't see the point in asking about every little thing. I don't see how stock sized exhaust piping with a straight pipe would not be ok on the car. It's all about the sound you want. You could put cherry-bombs on it if that's what you like.

AMS Performance has expressed numerous times that our stock exhaust system is just about as good as it gets. Add an x-pipe, some high-flow cats, maybe pick up a tiny bit of tq, add headers, and you're good to go. There's not much else you can do to improve performance from the exhaust.

You've invested a great deal of time and money into your car and I respect that. I also understand that English is not your native language, but please pay attention to your punctuation and sentence structure. It helps others understand what you are asking and helps to clearly answer your question.

thanks sir this is what im waiting to read in the thread. thanks sir.

yes sir. im very sorry also sir. i think u misunderstood my englsih. im very sorry if im not that good in conversing. yup thats what im planing to do sir return the stock exhaust system then put and X pipe and race reso on it. but to connect the x pipe to the stock exhaust system ill be using 2.5 inch pipes cuase we dont have 2.225 inch pipes available in my country. thanks sir

ok sir im so sorry but well taken sir. im not really after the sound im more after the performance sir. and the reson why im asking about so many things is that we dont have BENZ/AMG experts here in our country like you guys, thanks so much sir hope you undertsand.,

thanks silver logic!

[Lawrence1]

you don't have to apologize ... just understand that there isn't much gain to be had from N/A mods on this motor. you might get a few hp/tq here and there but it won't be much and not something that's noticeable(other than better/more sound)

Be skeptical about tuners who claim big power gains(40-50hp) from bolt-on mods on this car ... there is VERY little improvement possible and it costs more money that it's worth(cams, head work, custom tuning, etc).

that's why when you first started asking about mods on this forum i said that these cars are not worth modding unless you go F/I which again costs big money and will have an impact on reliability.


if i were you(and this is what i did to my car when i got it) i would invest some money in maintenance to make sure the car is in tip-top shape instead of blowing money away on these so called "mods". I bet a new MAF, a fresh set of air filters, along with new fuel filter and spark plugs will make far more difference than the aftermarket stuff you've done.

[saintz]

You want to keep as much of the piping 2.25 inch as possible. But using a 2.5 inch X pipe (or 2.5 inch high flow cats) is fine. The exhaust shop can easily weld a 2.5 inch X pipe to your 2.25 inch pipes. Don't worry.

[pinoyk20]

thanks so much guys! very bighelp. after the fix i guess ll have to stop modding the car and save the money to buy another car that would be easier to mod. thanks so much. i guess AMG did a good work on the w210 e55 maximizing the power on the stock form.

[amgalex]

Why would you go back to stock setup?
all you need is a custom tune to your new setup to adapt your ECU to new air flow numbers thats all, im sure you will gain hp over stock setup.

I may come off a bit harsh, but believe it or not I think I'm a pretty nice guy. You bring some good discussions to the community.

because im so hard headed and i didnt listen to AMS and simon evosport that the exhaust on the e55 is the right size and going bigger may reduce velocity and hurt performance. so i guess i learned it the hard way

ESH: thanks so much sir.

Stay with the 2.5inch,i just did my e55 w210,with our headers and a 2.5inch system,great pickup in power and torque,the only thing to watch for dont change the rear resonator as it results in loss of power and lazy throttle response,the rear resontor is straight thru,you can do dual 2.5inch all the way to the stock rear resonator,with this setup the off the line performance is incredible right thru the range,i will have a thread on it soon with pictures and dyno testing,at this point i,m not running a x pipe or cross over pipe,i,m going to test it with and without,also it hasnt been tuned yet,i,m leaving that for last as i want to extract as much as i can before the tune...stay tuned..

Its interesting you bring that up about the resonator, loss of power and lazy throttle response. When I first removed the resonator on my C55 I could swear my throttle response was not as crisp -- especially in the lower RPMS -- and I was concerned I had lost some low end power or torque. After awhile, I just shrugged it off as all being in my head, or thought that the ECU had somehow adapted (or, perhaps I just got used to it). I did several dynos this past year on a Mustang dyno in 4th gear and my car certainly seems to be in line with what other C55s are putting down (301HP/310 Ft-lb). But, of course, this is on a C55 so perhaps the exhaust is not affected the same way the 210 E55 is. I have a set of shorty headers I want to throw on next and am curious to see what the same dyno will read after I add those to the mix....

Soony is talking about the "final resonator".. in the W210 the final AMG steel muffler has the perfect flow & design. you only can change them to get other sound, but in terms of performance the factory AMG is the best ever

You can remove the center resonator & gain some performance in our exhaust systems

PD: Soony please stay informed about your changes! i'm very interested in know the difference beetween the factory size & 2.5"'s complete

wow this is a good update . i still have my stock muffler but i removed my resonator already. so i guess i have to modify the set up . put back the resonator on the stock location, then put the x pipe on the middle of my piping where my race resonators are.

pls post pics of the set up. thanks

[pinoyk20]

guess i have to wait for sonny's post before i do anyhting with my car again.

[Lawrence1]

what did you put instead of the stock resonator. This car only has one resonator in stock form. The resonator is placed right before the muffler on the exhaust piping. I dont see how you did your system with 2 resonators and a muffler?

can you take a picture of your current setup?

you shoud leave the factory muffler and add an x-pipe in place of the resonator. there should not be another resonator on the system unless you removed the catalytic converters and decided to put a resonator there in place of said cats. that would not make any sense though so at this point im confused about how your system is currently set up.

please post a pic to give us a better idea.

If I'm not mistaken, he put his X-pipe where his original resonator was and put 2 so called race resonators in place of the secondary cats.
