Diesel exhaust sound
 

Maybe some of you heard those modifies diesel engined cars sound. It's pretty cool, it has some echoes, ... well sounds are hard to describe :D
I asked someone how do they get that sound, he said the cats must be removed and that's all. Does anyone know anything about this? Does removing cats make some damage?

arent disels stinky enough to remove cat?

These racing cars are diesel, look at the smoke :lol:

There are some races with Diesel cars here and there isn't any smoke. There's somethin wrong with those Hyundais :lol:

LOL!

So if its Diesel racing cars your after look for black smoke eh? :lol:

lmao at that black smoke :lol: :mrgreen:

I think if you replace cat for the resonator (available for diesels? :hmm: ) everything should be fine :wink:

I doutb that will be bad for the engine but not so good for your emissions.
Afterall it's a turbo engine so less back pessurs is allways a good thing so remove it or get a sportcat.

Okay, I found out how do they get the sound I'm talking about. Sorry, I have no video, and I can't found one on youtube neihter. You have to belive me, it's a great sound, and nothing like a blow-off valve.
In case of a 2005 Astra they replaced the turbo with a variable one, and emptied all the mufflers and emptied the cat too (not replaced with a tube!!!). So this modification has any negative effect? Other than emission...
