2011 E90 (comp PKG) with dinan exhaust and differential (3.45)

vb_man · 09-14-2012, 04:50 PM

Guys,
With 6K on the ODO in the E90 2011 (CP), I just had dinan (Campbell in bay area Northern Cal) install the 3.45 differential with the free low exhaust today. The toy (car) is more aggressive than ever with the combo diff and exhaust. In normal driving mode it seems to be quicker/faster than the M mode.

The black tips really complements the car as shown in the pics. I do see a slight higher RPM of 300 at 80MPH but I do not put a lot of miles on it (2.6 years with 6K). The exhaust sounds great and not too loud which I was afraid of.

Any comments?

Not a fan of the thinner tin can exhaust tips, but I am a fan of the black color

I LOVE it!

Looks aight, sounds good. Fail on the 2 fake tips.

This has been discussed ad nauseam.

Big fan of the Dinan, no drone whatsoever. The 2 fake tips do bother me too, but I got over it.

Nice!

Fake as in two are closed? WTF!?

OP - beautiful car! Probably see you around South Bay someday...

vb_man · 09-14-2012, 11:02 PM

Thanks guys.. I got it back today and love the cars response (rev happy).. Only question is what to do with the old exhaust? I will hold it in the garage for some time and might dump it sooner or later.

Yep closed

Looking good. Love 3.45, have 40k miles and a ton of track time and keeps getting better, enjoy

positiveions · 09-15-2012, 11:34 PM

I am assuming you have mpg sacrifice, but who cares. It's a toy right?
I am indulging on the 3.45 idea.

Talk a little bit more about the diff. What made you choose the lower ratio of the two?

The 3.45 with exhaust does take some MPG off. I getting on average of 16-17 MPG where I use to get 18ish with out the 2 mods. But again, its a toy and I do not put too much miles on it. I like the 3.45 compared to the 3.62 (more torque) but that is just my taste. With the 3.45 (with exhaust), you can really feel the difference at all gears without the M button on. I not sure how much the exhaust has to to with the added power since I got both mods done at the same time. But I would venture to say that the largest variable is the diff and secondary is the exhaust.

Pros:
faster acceleration at all gears
excellent sound at all RPMS but not too loud

Cons:
will loose some MPG but this is all relative to the owner
cost but I figure if you have a M3, you can afford it

Not sure the diff makes that much of a difference to MPG as I can run a higher gear now than before. Also, heard problems with the 3.62 (enricobob I think was one) and that the 3.45, just like the car, is the perfect compromise. Really love the 3.45 and think it really makes the biggest difference on track or city driving, which is all I do. I highly recommend it and hope OP really enjoys it. Am sure he will
