thats what i was hoping for - at least some sort of louder noise than standard
but nope, it's just like i replaced the backbox with a nice looking chrome 1 , lol

what should i do?

To be fair if you have a 2.0 engine with a decent exhaust its impossible for it to sound cheesey, if it was a 1.4 saxo then yes it would  :laugh:

Was thinking of replacing the centre box on my vr, it already has a full stainless 2 box system along with decat and 6-2-1 manifold but its dead quite unless you boot it, was wanting it a little louder but worried about a lack of back pressure affecting performance so still undecided. :undecided:

wont loose no back pressure what so ever, the box is their to make it quieter at thats all daz...trust me do it, mine drives like a complete different car, feels alot faster and alot more rev happy if that makes sense, before with the box it felt like their was a restriction... as i just said mine flys now and its just the 8v at the moment, and the sound it gives off is awesome on a VR it would be imense, do it!, you cant beat the sound of a good stainless system

The middle box is the main baffler (sound deadener). Putting on a sports cat will make a bigger difference to performance and sound

I thought you could still pass an MOT with a sports Cat on! Thought it was just deCats that were a big no no!

Just that some people say that a vr6 needs to have a certain amount of back pressure to get the best from it and that if i remove this box will loose some low down torque which i don't wanna do, maybe i might do it and find out for definate.

Watch the ivd of the recent rolling road day to get to see how it sounds.

im a true beliver in the phrase " too much flow = no go" which is something the guys at Mongoose taught me whilst having the system made up for the jap car, but iv never heard that daz but i dont own the VR so its not somehting iv researched, as far as i know its just a silencer to reduce the noise level... id remove it, i bet u anything its a hell of alot better :laugh:
