[ian_79a]

Im almost ready to order my Eisenmann exhaust, i know ive spoke with some of you already pepperNike thanks been a big help in the decision department, heres what im going to order...

Eisenmann Race cat back , quad system 4 x 70mm pipes and sound pipe,

Is this a good choice would you do any thing different, Roy at ca-auto said that i could go with a de-cat and it "should" go though MOT i dont want to take the chance want to keep it leagal at lease not for now! :D and dont want it to LOUD!!!
im planing on fitting it my self any tips or anthing else would be great help

also getting Grupple m from teddy soon havent spoke to him yet!!
and ECU re-map with the re-map should i have it done after ive had the exhaust and induction fitted or does it not matter

Never fitted a quad exhaust on my 330 is the past so can't tell you what's involved. However, it'll be most helpful if you could post a little write up on your installation [ok

Difficult to say how much BHP you would gain until you put your car on the rollers with the mods on. Make sure it's the same roller under similar ambient conditions. It'll be interesting to see.

However, I can guarantee you that you'll be grinning all the way to the noise :D

i remember teddy has the quads on his 330 vert. Maybe ask him what was invovled. Unless he bought it like that?

I wouldnt expect much in the way of power gains from just fitting a backbox,sound pipes and GruppeM. The OEM exhausts are very good as standard. The noise however is worth it, awesome.

I wouldnt go with a decat and you would have to find someway around the fault light that will come up. Racing Kats would be a better option. But once you start to replace anything other than the first 2 resonators, things start getting very loud. You say that your going from the Kat back, this will be VERY loud, just ask Nick:D

Quad exhaust will double the noise so it will be LOUD anyway, might be ok if you have a coupe but on my old 330 vert the quad exhaust were killing my ears so I had to get rid of it. There isn't really any noticeable performance gain, however the noise make you think the car is faster anyway lol As Lee said the standard exhaust is pretty good already, just quiet. Sometimes getting a straight through exhaust will lose too much back pressure and results in losing low end torque. The extra ponies come in in mid to high end.

Thanks for all the info, based on what your all saying is it worth spending £655 just for the noise?? :confused: is it not worth spending less on a cheaper cat back? or is this just better sounding

[ian_79a]

will the sport exhaust be loud enough or should i still go for the race version??from the sound clip its hard to tell be it sounds better im not going for the loaudness more the tone

its worth every penny lee sounds so nice its not loud but also you are paying for the quality as well you can get a cheaper system but you will not be happy with it and will cost you more in long run [cool get the Eisenmann

I've got to say that you can't go wrong with the Eisenmann. It is so worth the extra cash. Looks and sound will be awesome. The noise thing really is subjective. To fussy sods like myself, even the quietest (factory sport) was a little too intrusive so they made me a custom quieter one :D . But others on the forum can have a race system and think it is just right. You'll just have to take the plunge (but whichever you go for, I am pretty sure you won't be disappointed).
