just today i'v removed the pollution filtration system from my E55 and changed it with a stain stell exusts. if you notice there are 4 filters,two on each exust pipe after the menifull to the middle box. and it pulls much easier and faser now, and it sounds really cool, even better than Audi S8 !! i really liked it and i feel more power in my engine. my friends noticed the difference too.

theres that little factor here in the us, its called emissions testing. Can't remove the converters unfortunately. Also, I wouldn't mistake louder noise for more performance, which is common. Most likely the decrease in backpressure will result in less torque, but possibly more horsepower.

And you can't register it in California under any condition, and the police could theoretically impound your car if they noticed the emissions gone.

Good goal. Bad implementation.

guys, if i am going to put in mind police and dont know what, i cant add even 1 hourse power to my car !!! so, what i did is that i can fix the original exusts any time i want, by removing the stain steel, and fixing back the original one before registering, so easy
shortly am going to add a NOS system to my E 55 and will tell you about the details later

When you say "sounds really cool" like does it sound deeper?? With more growl?

dear jam, it really sounds much deeper with more growl, specially when i accelerate more, so when it shifts the gear from 2 to 1, or 3 to 1, the tourqe is much better than before.
