335i golf tee mod

e.n335 · 06-30-2007, 01:35 PM

Hi

I want to do this mod and searched, but I did not find an answer to the question: Do I loose low end power / torque by doing this mod on the 335i ? I don't believe so, no aftermarket exhaust has a flap and backpressure is not good at all in turbocharged applications.

I would appreciate if somebody really knows ?

Thank you for feedback.

Eugen.

lol it was some girl who said it or something and that was it, and it was probably a butt dyno, and yet people keep bringing it up

who really cares though it opens sooner than you should really care if you have full power or not

There is no low-end torque loss with the goft tee mod. That flap is mainly there for noise reasons.

We haven't built harnesses ourselves for nearly 2 months.

my car has been this way for most of its life and i love how deep it sounds on cold starts... no change in performance that i've noticed..

e.n335 · 06-30-2007, 01:45 PM

Purpose is sound only, thanks.

BoostedBMW · 06-30-2007, 01:49 PM

Eugen... you pretty much answered it yourself in your first post. I feel the same way, since back pressure is never a good thing on a turbo car, having that flap closed wouldn't provide any type of benefit with having more of it. I think its there only to keep the exhaust quieter, I can't see it losing any torque by having it open.

Sal@AUTOcouture · 06-30-2007, 02:17 PM

Mine's been off since the day I got the car. I LOVE the way it sounds on cold start-ups

How can you make posts like this and then go say I don't know what I'm talking about?

Ummmm, because you don't.

One is not contingent upon the other.

haha thanks Judec! I was wondering, and now I understand completely. Almost all BMWs have the vacuum exhaust flap, mostly for noise reasons.
