[@Jesus-bmw]

why is everyone disliking the video lol 😂

[@MegaJugMan]

Probably because they don't have a V8!

[@cbrenovations]

Shity sound

[@HEKTIC458]

Sounds mint

[@user-se4gi4nr2f]

Very Nice!

[@abhaxus]

Is there any chance you could post a video focusing on the intake only? Would love to know how the blow off valve sounds with this vs competitors

[@GammaSouljah]

N63 is MAF based engine not MAP.... You cant use a BOV with it.......

[@paulovincenzo]

Sweet

[@Joseph.Kim913]

Is this on stock exhaust setup? With just the catless downpipes?

[@bigbezzee]

I want to know too. Sounds straight piped..... I have a N63TU 550

[@Khercules]

It's on the description. It's all stock apparently

[@Fuckntastic]

Anyone knows if it needs reprogramming or tuning after catless DP installed, will show "high pressure charge air" message on 2011 bmw 750Li?

[@SINasTER75]

Didn’t have any problems with my catless DPs on my 550...
Had problems with their intake (the old design, don’t know if it still messes with the MAFs like they used to).

[@johnq4196]

do they fit better in 2021?

[@MrEvilTag]

So so many downvotes??

[@pyrobocaj08]

Why tho

[@SINasTER75]

Because they have major design problems. Had to practically unweld and remake both DPs so they could fit on my car!
And they never post any reviews on their website if it’s bellow 4 stars, which is very bad practice for a seller and performance parts maker

[@DeJonWilson1]

@@SINasTER75 what was the cost for this? My mechanic just called 10mins ago and said exactly the same thing. I’m sick!

[@SINasTER75]

@@DeJonWilson1 I was lucky, I’m really good friends with my mechanic and he only charged me 50$ extra for the 3.5hrs of extra work, all the cuts, welding and practically making new downpipes from their product

[@skandinavianfmd1991]

Bad idea
Done mine 650i got lots of smoke 💨 every time you drive 5min and stop in every traffic light 🚦 and it stink badly
Warning ⚠️ don’t do down pipes
I Change them back to stock

[@tehgzizlauw1787]

Put some free flowing cats with your downpipes

[@hussamalghamdi5155]

What you have is probably valve stem seals problem and not a cat issue. Putting back the cat does not solve the problem it only hides it

[@ericsens4070]

CROCO SS that’s what I had on my n54.

[@landofcivilization7894]

Would u like to sell ur downpipes

[@matreyia]

Your vehicle is damaged. The downpipes did not cause the damage, it only revealed it because stock cats hide the smoke. Engine is damaged - valve stems or piston seals...etc.
