Eisenmann exhaust

[mukgnem]

HI, I'm new here. dun really know and not used to navigate around the website for this topic.

I am wondering whether an extractor would help my E46 to go a little bit faster ,as it is sluggish now. Any guys or gals able to recommend ...

Most people will say that extractors will make you lose some ompfh at the low end due to its high flowing nature. Perhaps getting your ride tuned after installation of extractors is necessary?

I second that... i think you lose back pressure for NA... but on the whole you gain

To mukgnem,

dunno about specific stats, but after i install my extractor on my e46, gut feel is my car became very powerful, like monster. serious. a little back pressure was lost but very neglieable. so low end torque lost was also negli.my sepang track timings saw great improvement

hope this helps u!!!!

Usually what brand of extractor , ppl in this forum recommend for the E46. locally made or those german made type.
I convince that the header would add hp to engine. only thing is would fc suffer.

[SHAMELESS]

FC not much diff....

locally or taiwan/thailand made ones are better than the german types.... better design...better, smoother flow...

[mukgnem]

I suppose U must have changed the muffler as well, and oh, btw , any pre-cat removed

[SHAMELESS]

for e46, if u change aftermarket headers, cats are removed.

[mukgnem]

cat's gone, eh. that's good. thanks, fren.

E46 to E90?

See the design below.

E46 330 Eisenmann



E90 320 Arqray Exhaust



The answer is NO.

If it's E90 330 Eisenmann, then it'll fit with alittle modding..........

How come you keep asking this question har??

Hi! I am in the planning stage of modding my stock exhaust manifold / mid pipe & muffler for my E63 (630CI). Just to check does Eisenmann make any straight thru completed exhaust kits from manifold without mid pipe all the way to the muffler for off road use? What's the biggest internal diameter of the piping? I prefer internal pipe like 80mm to 95 mm if possible in titanium with quad pipe?
