Extractors certainly change the sound, your car being efi the sound would be intresting to hear.. You would also need to think about the ass end muffler that you would like to use.

To give it the deep sound im not sure, but the above will help in someway,

The cheap way is some holes in the exaust before the mufflers, otherwise look for a straight thru muffler.

alright.. my calais used to sound like a V8 (was an efi 6).. heres what it was running:

Extractors
2.5" from the cat back, single muffler
mild cam

gives off a nice V8 rumble.. i loved it.. the cam gives it the V8 burble on idle..

VK EFI 202 all had extractors from factory.
2.5" inch from collectors back sports muffler and a resonator at the rear, work well for Mine.
Many people think mine is an 8

I find that the Genuin VK EFI extractors flow better. There is no sudden bend as soon as the exhaust leaves the head, as EFI manifold gives more room, carbie manifold force the extractors to bend down straight away.

Yeah have to agree, im happy to say my vk efi has a really good sound. lots of people ask me if its an 8 as its heard to distinguish. Im usuing factory GM extractors with a 2.5in straight through, with a small muffler towards the rear to stop 6 Cylinder drone, people also use resonators to extibgush drone, however i feel it takes some of that good black motor sound away, less rumble. I used to come off the freeway drop it back a gear and use the engine to slow down, man did she burble, its a good feeling.

Did the 2.5inch straight through come stock aswell on the VK EFI's or is that an aftermarket thing
