I say no. I'm a purist when it comes to cars. I also wouldn't want to deal with it if something went wrong.

 

i would do it, but have a remote tune done...by someone like jerry at eurocharged. why could they not tune you remotely? get a wideband and bring it to a local dyno. a road tune is just as good.

 

Mike,
In your case, its a why not kind of issue. Though I like NA, and would personally rather spend that money upgrading to a GT3. However, being that you have a number of sportscars, I say do it.

 

Yes! :d

 

Well would you use it? I mean have alot around, so its nice to make the M3 the best it can be, but is there real value to you? In terms of motorplan, you would be on your own but I'm sure BMW would not mind, should something go wrong, to help on your account. In my side of the country they actually turning a blind eye to modified 335i's on motorplan. Your modification is a little more extreme though.

This all being said its under 7 to the $, so if ever there was a time to buy its now.

 

i really would go for it and i know ESS warranties their work, seems like a really reliable system, and i'm sure any they could help you deal with a problem if anything were to arise

 

Never been a fan of adding forced induction kits to NA cars. I'd say leave it.

 

Mike,

Id just go for it! ESS' products are certainly quality and you really shouldnt have an issue.

 

Why don't you add two doors and grow four cyclenders.... Oh wait
No is the way I voted

 

How to make your M3 sound like an F1 car:

1.) ESS SC

2.) straight pipes
