Silencer removal?

[BLACK 330]

Hi all, question,will it be advisable to remove silencer before the last big box. Had my center cats removed. Sounds good but not what I want.Would like to get more of a rasppier M sound. Its a 330 steptronic. Any help.Would like to keep rear box standard.

if you want rasp it should do the trick

 

[Karthik]

Wouldn't this make the car very loud ?

 

[moranor@axis]

the back box does most of the work but yes it will be louder but probably not near as loud as most citi golf free flows :rollsmile:

Hope Black 330i does this mod and puts up a video so I can hear :rollsmile:

Replace the backbox with a Van der Graaff and then come tell us what you think:thumbs:
Alot of people says that my car sounds better than a M3:fencelook: oh...and i gained 8kw according to dyno runs:joy:

8kw from replacing ONE box?

Maybe he got the 8 KW from the Van der Graaf generator :fishwack::rollsmile:

Guys lets not go off topic , Van der Graaf exhaust is probably big bux :thumbdo: and this rear silencer removal is like just fitting straight pipes

 

[Fordkoppie]

......."De Graaf"....... = Exhaust

then why is it expensive?

 

[hiltonfa]

Can't see a rear box producing 8 extra kw :nonono:

Damn!! Really?

Cos I have 2 of them! How disappointing

Unfortunately its not THAT easy.... remove or replace rearbox and get 8kw for free doesn't work!

The whole exhaust is a well defined system and it is compulsory to have fundamental knowledge of what is going on in an automotive system!
Lots of calculations needed to get a "legal" system perform in Europe.

Their "Export Versions" are much crunchier (noisier) but pricing depends on development time and time equals money...... thats for the "why are systems so expensive" question :=):

Yep..hard to believe i know but that's according to the dyno runs and I was like Wooooow:tease:
Anyway...my car pushed 162kw before the box and after the box it pushed 170kw on the same dyno at zeemax..and the difference in accelaration and performanceraise:raise:
But dont take my word for it...just my own personal xperience with this backbox i've put on my car:thumbs:

 

[Rolf]

same day dyno run?

 

[speeddemon]

same day dyno run?

Nope...2 months apart...but like i said..i dunno the ins and outs and how it works but that's the figures i got..
In the 2 months apart there was nothing else done to the car as well..
all my other dyno runs before all this i was in the 150 to 160kw bracket

154kw standard
3 months late..UniQ chip plus decat= 162kw
2months after that...Van der Graaf backbox= 170kw

this is what led me to believe that I gained 8kw :fencelook:
Also the performance i got after the backbox was very noticable.

Lets leave it this way :thumbs:

Van der Graaff backbox is not expensive. Cost the same as any other backbox but as its a generic product of RGM you are well off fitting one. I wanted to fit one but the pre f/l e46 exhaust system goes from two pipes and merges into one, The Van der Graaff box uses two inlets and twin pipes at the back.
