Stage 2 BMW F90 M5: Your not going to Believe this!, Sports Cat vs Decat results are on

[@M5tubee]

I would love to see someone do a full transmission fluid change on these f90 m5 would be amazing

[@AB-sy4gx]

Currently own an f06 m6 but these videos make me want to sell more and more. Might go and grab an m5

[@Herofmine]

I came from f10 m5, now F90 it’s another level when it comes to speed and power

[@petrolsunny]

More magic from Velocity Tuning. Thought you had some bionic implant for a second there 😂

[@velocitytuningltd]

How much will this bionic implant increase my bench by? 🧐

[@petrolsunny]

@@velocitytuningltd 50% increase easy I reckon 😂

[@ajc2100]

Surprised me as well. Obviously expecting to pay more for sports cats, but the convenience of being legit with virtually the same real-world performance is huge

[@velocitytuningltd]

Ill be figuring a package making use of them

[@jessegriffith6401]

What brand downpipes are they?

[@luiscarlosmontanosaenz7717]

Good videos. But I wonder what happens if instead of buying primaries with 200 cells, you only leave the primary downpipes free and leave the car's original secondary ones, those are smaller.

[@jonnyprice8296]

I’m In the market for an F90 and these videos are mega cheers👍🏻

[@psychinbruh]

former f90 lci owner here with FULL straight thru exhaust with decat. the car seemed faster with valves closed. the car likes back pressure. they run better with the stuff that has to have on it like cats and mufflers. bmw engineers🫡

[@douglaspipitone2726]

A little more back pressure affects the wastegate control from the dme

[@RedDwarff]

I have a Fiesta ST 180 stage 2 240bhp , I changed from a de cat to Scorpion Sports Cat and the mpg was 35/36 mph with a de cat ,after sports cat fitted and full service including plugs also switching from Shell V power 99 Ron to Momentum I'm getting 39.3 mpg. No smell now when driving with the windows open no noticeable power loss and passes the MOT

[@douglaspipitone2726]

I wish I could send my car to you velocity Tuning would love to be a customer of yours

[@douglaspipitone2726]

Catless down pipes on f90 with a jb4 made 1.78 1/10 mile improvment and .4 sec on a 60-130 hit real life numbers

[@gunit00099]

Anything you touch Tommy it just becomes fast 😂

[@markgtrheyes]

Apparently DVSA are cracking down on companies offering decats, so seems a decent alternative

[@velocitytuningltd]

We did see that also

[@wuzumaki]

Is Stage 2 possible with only secondary downpipes and x-pipe, or do I also have to go catless on the primaries?

[@ig-m5_lee]

Tom I can only guess it’s the IATs?? It’s winter time there so them cooler temps help big bertha.

[@velocitytuningltd]

Dyno runs were same temps and draggy also been run in similar. One changing factor is its on custom gearbox map now which makes a noticeable difference.

[@STEVEBHPDEVON]

Brilliant vid and so intresting as i perfer the sports cats as dont know a friendly mot man 😂

[@velocitytuningltd]

Its a good option. The fact the power difference is so close it makes it a great way to stay legal.

[@jonathanlinehan9316]

Awesome video love it

[@unkowngaming9250]

what sounds better tho ?? dose the sports cats make it have a nicer tone ?

[@paulmartin9788]

Great video

[@velocitytuningltd]

Thanks Paul

[@ichirakuramen7582]

I currently have a stock m5 with bootmod stage 1 OTS map. What gains do you typically see from a stage 1 to stage 2? Debating if spending the money for exhaust to go stage 2 is worth it.

[@grahamorourke7155]

What brand of sport cats are these ? Answers backed up with facts. 👌

[@velocitytuningltd]

They are from a supplier we use they will be listed on website in 1 week

[@wadeverch4774]

So, with sports cats can cold start still be turned off or should it be left on?

[@dwayne8667]

What fuel are you on for 840bhp? I was under the impression your stage 2 made 800.

[@velocitytuningltd]

This is 99ron, we quote 790-810 but some make more.

[@dwayne8667]

@@velocitytuningltd Nice. I'd love to see this car on AutoTopNL. He's tested multiple stage 2 M5s and they're mostly in the 6s range 100-200.

[@isamalik2696]

What CEL are these downpipes?

[@UKBBALLER14]

So did it fail the MOT emissions when de-catted then?

[@letmeknow4167]

Yes it fails with decats. In the US they have machines that detect after market tune. If u have cats with tune u fails as well

[@MartinCollier-k6f]

820 wasn’t a bad guess then

[@velocitytuningltd]

Better than mine lol

[@bmwmd110]

Can i run stage 2 with stock secondaries and catless primaries? I don't feel like doing the secondaries lol.

[@velocitytuningltd]

Youd be better on sports cat primary and no secondary

[@bmwmd110]

Eh yea, I'm just going to pay someone to fit them. I did my DPs on the F10 and F85 but the F90 looks like a pain in the ass. I went under to remove the belly pan and it look way tighter than the F10 for some reason. Plus, I'll have to drop the exhaust and that's not easy without a lift. @@velocitytuningltd

[@jamesfeltwell7871]

Which coolant expansion tank are you using?

[@velocitytuningltd]

Im currently trying all solutions. Ive not settled on one

[@joshuakellner6168]

Are you doing these sports cats for the F10 M5?

[@velocitytuningltd]

Yes we will have for sale within 2 weeks
