Secondary Downpipes DIY on my F90 M5 - Loud enough??

[@carsacrossminnesota874]

Hey man, love the content, what model of quick jack do you have? I know that f10 m5 size wont work on f90

Hello, great video, after installing the downpipe, I have an exhaust smell in the cabin and when I open the windows this smell is very strong, do you have any idea?

[@LenartoGarage]

It could be that you have an exhaust leak. See if the smell is strong under the hood. If it is, you may have a leak.

@LenartoGarage thanks

Did you have issues getting that clamp that comes with the MAD downpipes on the driver side main cat with that brace on it? The shop ended up putting the stock clamp back on because they couldn't get the clamp MAD provides on the driver side primary cat.

[@LenartoGarage]

Yep, I ended up using the stock clamps as well.

I wonder if this mod is more noticeable with MPE, since it’s valveless.

[@LenartoGarage]

I would guess it would be more noticeable.

[@atruetone]

@@LenartoGarageI will find out soon enough. Having my secondaries installed next week

[@LenartoGarage]

How's the sound with the MPE?

[@walt9427]

Man, I'm disappointed to hear this. I ordered a set of secondary downpipes to go with my custom exhaust I had built. I think you will have to get rid of the stock Exhaust as it is still restrictive at the rear with that middle box between both mufflers. Did you already remove the resonator in the middle?

[@LenartoGarage]

No, rest of the exhaust is stock.

[@walt9427]

@@LenartoGarage ok. I just saw the other video where you added the primaries. You should consider removing that resonator and adding the Dinan x-pipe if you want more volume.

[@LenartoGarage]

Did that add any drone for you?

[@walt9427]

@@LenartoGarage no drone with the setup i have. Valvetronic system with secondary catless downpipes.

hola alguien podría ayudarme com datos reales si puedo usar solo downpipes primarios y reinstalar los secundarios. Estoy usando MHD ots stage 2 algunas veces con E30, pero no me gusta el olor del escape directo quiero instalar tal vez los secundarios originales. pero sin dar algo no se si sea posible pero aun me sigo informando apreciaria algo de informacion is a bmw m8 coupe

[@LenartoGarage]

You can install the secondaries and keep stage 2. It won’t be an issue. The primary cats are the main restriction.
