Anyone know or have a round about guess? This dude told me 40hp and I said bull ****....
Thanks guys

X-pipe = 8wheel HP above 5000rpm, better low end part throttle response below 2500rpm. not much change in the mid range.

High flow 2nd cats = 10HP/12TQ @ wheels on dyno
2nd cat delete mod = 12HP/18TQ @ wheels on dyno

X-pipe & 2nd cats combined = at most probably 16-20HP/TQ... not 40HP/TQ for sure.

AMS- Dropping knowledge/facts as always

Awesome. Thanks a lot. I'm welding up my own x pipe and straight pipes to the stock muffler this week for sure now

AMS Performance

Make sure to use 45 degree mandrel bends w/ the X-pipe in order to replace the stock resonator. The 2nd cats just replace w/ the high flows or delete w/ 2.25" inner diameter piping (stock 2nd cats are about 18" long).

Hope that helps,

any significant sound changes when removing secondary cats? Any additional droan?

X-pipe, resonator delete and secondary cats delete = How the 55 should of sounded from the factory. No drone, just a nice mean growl when you hit it

Should I still be able to pass California smog (aside from the visual) if I do this? 16-20HP and the sound is tempting..

MIKESV8

is it the same for my car?

Can anyone tell me what high flow cats I can get for the primaries?

My check engine light is on, and I've narrowed O2 sensors. So I'd like to start working on the exhaust. Who has these for our car? I need to know where to look

armaniE55

PM AMS - he knows the E55 exhaust very well and can recommend one.

P.S - good job out there with the Spill

Thanks man....We are officially done in our part. We just got back from Dry Dock in Tampa yesterday

I have a 2003 E55 AMG station vagon and need a replasement engine.
Can anyone tell which engines fit in this car preferably a bigger one.

The engin is A113 140 0 412

The 2003 E55 is a W211. This is the W210 forum, so you won't get as much help here. I would start a new post in the W211 forum.

If a 5.4L supercharger V8 isn't big enough (and lord knows it's not), you're looking at the 6.2L V8 from the E63, which will probably fit but require all sorts of electrical work. This really is a poor choice, because you're losing forced induction with this motor and really taking a step sideways, if not backwards. Your next option is to shoe horn the V12 twin turbo.

You probably want to replace the motor with stock, and just add a pulley and ECU if you really need a 7 passenger car that does 0-60 in under 4 seconds.

vidarsig

that rules out a begger engin.
so the 113 is called w211.
This is what I need to replace my broken engin ?

W211 is the chassis designation for your car (W210 is the old E class 95 - 02)

M113 kompressor is the engine designation for your car (M113 N/A is the V8 same as yours but normally aspirated)

You need to go to the W211 AMG forum not W210 AMG

C55 exhaust system is not exactly identical. However Hooley did do 2nd cat delete and got 13HP/19TQ just from 2nd cat delete. You can't really do the X-pipe on C55 though like you can on the W210 E55 system.

Both motors though absolutely love headers, it really is a must for these NA 55s. The stock M113 manifolds really are pure junk.

Does anyone have a kit available for the x pipe and cat delete now? or are owners piecing together the parts on eBay still?

desired_speeds

We still have to piece together parts from ebay. It ends up being no more than $70 for all stainless steel materials.

fangtl

Thinking of doing this mod, can someone just confirm the following pieces are what I need?

X pipe: http://cgi.ebay.com/T304-STAINLESS-S...item35a40bbaf5

then two of these 45 degree pipes

Pretty interesting thread, just curious about the e-test question. Would it still pass the e-test with the 2nd cat deleted? If it does, this will be my first project this summer. Thanks.

fangtl

I had my cat and resonators deleted back in November, currently running xpipe then straight thru to the mufflers. I just passed Virginia emissions last week.

badblackbenz550

still waiting for ams to make Headers for CLK550...

TO_MB

Thanks for the reassuring info fangtl.... will put on my list for his summer

MBFLO

I have resonator delete and if i was to install those pipes listed above that would that give me the xpipe and second cat delete ? Is there any drawbacks to the car or does it basically just make it sound meaner ?
