Looking for some advice from you guys.

Running the Cobb & bms dci

Thanks peeps

Heard I wouldn't pass emissions with catless. This true?

[Treize]

yes

[marcvtec]

Yes you will pass now it is codes only.
Do not get them, your car will only spool faster and run faster lol
One of my favorite mods honestly

[skip2mylou123]

I wanna get them too. But worried about the smell.

[s142nv]

No problems whatsoever with smell.

[TeinBMW]

Definitely worth it!

[phlipino]

i have active autowerks dp's and theres not really anymore smell then stock because of the cats in the midpipes.

but definitely a big difference in power with a tune

Catted downpipes... why doesn't anyone go for them?! how much performance loss do they offer over cattless downpipes?

[wreckz]

Running downpipes for more then two years will most likely throw CEL codes
there is a group of people on an other website working on a solution for this
it can't be linked here so just google it. That being said downpipes sound beast..!!! and you do get a bump in whp

Are downpipes necessary when it comes to reliability and longevity of a tuned engine? I am tuned with a fmic and running 17 psi. I am happy wiht the power and will not be modding from this point on for power, but if it is a mod that will keep the engine in better shape I will definitely do it, which is why I plan on getting a charge pipe soon. Is downpipes just for performance, am I safe keeping my stock pipes in with my tune?

[TeinBMW]

Yea you should

It takes away a lot of back pressure on these tiny turbos we have,
So if you plan on keeping your car for a while and running a tune it is good to help prolong the life of the stock turbos.
As a bonus you get better performance and spool.
It's a win win scenario.
