Loud custom exhaust back box delete?
Hey guys.
I saw a company in the UK that sells custom exhaust systems. They told me they can make my car sound as I want. I said that I want something loud but without touching cats because Im from Belgium and they are quite strict regarding emissions (pollution thing) here. So they sent me a vid of an exhaust they fitted on a M3. The thing is that they deleted the backbox and thats what they also recommend me to do. And they can also put a valve tronic system to it. But I wanted to know, if I delete the backbox, could it somehow «*damage*» my car?? And what do you guys think of this exhaust/sound? Im still thinking about Remus non resonated but the good thing with that custom exhaust is its price lol. Thanks for your help! |

That will make it a little bit louder. If you are talking about the muffler, that will make it a lot louder but valves wouldn't do anything.

IMO it really improves the sound, makes it sort of exotic and proper. No more rasp. |

Valve controller can make it loud all the time instead of only in first and second under throttle.
I went from stock to CG controller and that made the exhaust much louder all the time. You can also just unplug the valves after they are open. Stock exhaust is pretty loud with valves open. In Sport+, I think the valves close after second gear and on downshifts. I now have AWE with valve controller. Sounds very different than stock and is a bit louder (probably due to secondary cat and resonator deletes). |

If you delete the muffler box altogether, what is the point of a "valvetronic"? Usually the valves close to redirect the entire exhaust flow to the actual muffler box. If you delete your muffler box, there is no point to a valve system as there is no other option for redirecting the flow.

Not sure how you can have valves on an exhaust system without a muffler. That would probably make it so that your exhaust is closed with no where to go. That can't be good for your engine.
