Hi guys, found this video, this was taken back in July 2011. Car ran 323 wheel horsepower and 340 ft-lbs with air filters and resonator delete.

Solid numbers

 

323/340 without even the secondarys gone is very strong... nice

 

wow 4 more RWHP than mine with exact same mods. nice!

 

Oh Michael I was going to ask you when you got your Eurocharged tune did you notice a huge difference? I just ordered my cable so it can be done remotely. Any difference in seat of the pants feel or fuel economy?

 

Very strong!

 

it's been almost a year now since i had my flash and dyno, i'll update my thread i made with a 1 year experience when that comes around next month. you can definitely feel the difference with the flash, specifically in the 3k to 5k RPM range IMO. the gears do swich faster and I do get better fuel economy, and it does lean out your engine safely because i noticed in the base dyno and post dyno there was more smoke coming out the exhaust in the post dyno. i've driven the car to nevada and back and did a challenge there with all my mods with no problems at all with engine heating. knock on wood the only thing that has ever happened to my car while i owned it is the idler pulley going bad which has nothing to do with the flash.

 

Going to remove my secondary cats next weekend. What dyno numbers can I expect? Maybe a 5 WHP increase?

 

I think the exhaust system ties up a total of 30 HP not sure what component contributes the most HP increase though. You should consider the resonator too because I did the cats only at first and there wasn't a very noticeable sound increase I was looking for.

 

Oh yes resonator is long gone. That made a slight difference but want to go the next step.

 

wow mine did 285whp with filters.. Than the tune bumped it up to 303... Im barely above sea level and it the car was fast.. hmmm

 

On wednesday I´m doing the Kleemann headers & downpipe,
and primary cats get deleted.
Can´t wait!!!

 

For the guys above with exhaust system mods, how does it change the note? Much louder than stock I imagine. The stock has a really beautiful subtle low end rumble that goes away at highway.

 

A 3" true dual with an X-pipe and secondary cat delete should net some decent hp. That's pretty much the set up the E55 guys run. Long tube headers would be fun too.

 

Interesting - I did a ECU reset before I went to the dyno shop drove it pretty hard out there, let it cool down for 30 minutes before the run, ran with brand new OEM airfilter and 94 octane fuel. I too was very impressed with the results.

 

The resonator is a nice touch. It is still quiet at idle until you get on it, its not C63 loud with just the resonator. I'm going to do the cat delete most likely tomorrow during my lunch break. Dyno run #2 will come mid May once I get some holiday time. Dyno run will consist of Resonator / Cat delete as well as Eurocharged Tune. Hopefully good results! Stay tuned!

 

With headers and the primaries deleted the car is definitely louder. Best way I can describe it, is it sounds like a DOHC Cobra with exhaust.

I love it. Someone quiet when just putting around, but when you get on it. Sounds awesome.

 

Now I´ve done the Kleemann headers and deleted primary cats.
With the resonator deleted it sounds really loud now, really
bad ***-loud! I´m considering putting the resonator back on.
The car is rocketfast and at full throttle I can easily blow the
hats off old ladies out strolling...
Kleemann showed me a dynosheet on another car with similar
setup and it showed 414 hp enginepower and 576 Nm. But of
course it´s different from car to car. They tested mine and
said it goes really well...
I´ll write a seperate thread with pictures from the procedure
at Kleemanns soon.

 

Video or



Congrats, I can see where some might want to tone the Kleemanns down a bit lol... personally, I like mine just fine with no resonator and no cats at all...just like Nactsturm said, she's nice enough until you give her the spurs!

Looking forward to the details

 

This past week, I had my secondary cats deleted - worth it! Sounds very very nice. Normal driving its not to much louder than stock until past 1/4 throttle it sounds fantastic!
