Since I decided to switch to a superior design to run it on my beast, I would like to get rid of those.

Photos of the ridiculous headers, mids and exhaust when i used to run them on my ride.





Here are some pics of the MHP Race Exhaust Tips which are manufactured with the latest technology after using for not that much

I already have a local buyer who's serious to take them for $4000

So i will not accept anything less than 4800$ due to shipping and custom charges.

what will you do after you have sold this system?

I suggest you get MBH headers and supersprint x-pipe

MBH sound is even better and outputs more power for the M156 platform

Good luck !

That is probably the funniest thing I will read on the internet today.

GLWS Sirex....i would sell them local and be done with the whole deal right away

sounds better outputs more power

pretty sure that all long tubes are fairly equal . i would say keep the headers and just get the x-pipe

Bro, why are you even selling them?. Its not like you need the money!

just take them and throw them where they belong. In the trash. Record a video for us when you happen to do so

propain

That would be cool to see. . How about give them away to a lucky forum member? Run a best video contest or something. Just have them pay shipping.


I wanted to see the jsp crusher video too but that never happened...

45-50 RWHP isnt funny. that my friend is called business

but your 454 RWHP dyno prior to your custom tune 468 RWHP is really what makes me laugh

Check out the dyno with C63's runing with MBH and an even "moderate canned tunes". the least I have seen is 461RWHP

Funny? . I dont think so!

dodger63

I read this a few times and don't understand can you say it clearer nmh is giving 45 mor rwhp then mhp?

SLS Qatar

Before you start laughing go and look at dyno sheets and you will see that MBH headers output more power for the M156 platform

We'll see who'll be laughing at the end

Talk is cheap. Lets see it. I believe you only have one example of this. Dynos have so many variables you cant base your facts on just one example. You need many. You also need to show the proof on the same dyno on the same day for it to be 100% accurate. Even then its not fool proof. Maybe one run the engine was cooler than the other. Maybe the temps came up. Maybe the humidity dropped. All these things can change results.

So who cares about the dyno. What are the top cars in the 1/4 mile list and what headers are they running? Real world results.

BAD430BENZ

you sure about that....i just saw less than that

BAD430BENZ

it doesn't come out on the video but if you go into YOUTUBE and watch this video , the owner claims it did 431/403

Dynos are pretty much worthless unless you are using them to document gains or for fine tuning AFR.

Here is a perfect example how different dynos can read differently with the same car.

I hope this doesn't turn into another I hate MHP thread.

BAD430BENZ

when your whole life revolves around hating MHP , i can promise you it will

SLS Qatar

Where is the dynosheet?

claiming?

SLS Qatar

Well I would t two etell you to do the same thing. two cars runing with the diffrent headers and have them run same time, condition, place...what ya think?

SLS Qatar

He never said MBH gives more 45 RWHP than MHP.

He said MBH gives 45-50 RWHP gains. and thats proven. Many dyno sheets besides Xtyper are available.

bluejae

that's correct. dyno was done on a mustang dyno at autoscope in dallas tx. it was immediately after the header was installed. i believe at the time it was eurocharged v2 tune. october of 2010

then in july 2011, i did another dyno at the same shop before getting a v3+ eurochaged retune. before numbers were 437/403. changes were ROW airboxes and bmc filter instead of k&n

then the dyno after the v3+ retune came out to be 471/438. this is with no break in time but i'm not sure how much that would make a difference.

anyways, good luck with sale. i just wanted to share some info.

BAD430BENZ

the dyno sheet ????? oh yeah , i have it framed on my wall

i'm not claiming anything . the owner of the car answered the question on youtube . look it up and you will see below the video that someone asked him for the numbers and he answered .

_AMG_

GLWS Sirex.
Which header setup are you thinking about going with?

BAD430BENZ

thanks for the info . he was saying he hasn't seen anything below 461whp and i wanted to show him that it has been lower .

SLS Qatar

I dont take claims. your the one that want proof. show me the dynosheet. Owner could be postin a number from his mind while he was drunk.


If you want numbers. Go check out my Brother's SL63 when it was NA. His car dynoed 465 RWHP @ 88-80F. hit "SL63 dyno"

Show me an SL63 that made better numbers....I'll help you. you wont find any!

btw, he has the MBH Headers

propain

I think that could be easy to do. What tune though? Soon as you change the tune it changes another variable.

thank you for noting that. that just shows how correct we are about MBH making more numbers on the dyno.


Did you see that Badbenz?

your own video of the white C63 you posted made 471RWHP
