Quiet exhaust for an s2 coupe, what is possible

[s2_wot]

I'm going to put a custom 3" exhaust on my s2. I'll have to have a cat and am planning to squeeze the wastegate exhaust out seperately and merge with the rest of the exhaust just before the cats.
I had a look at it earlier and don't see too many issues other than the carefully placing things and hangers for the wastegate section.

Custom 3" downpipe and all going well 3" over the back axle too. I'm not too bothered about the tailpipes (oval round twin etc).

The car should be topping out at say 320bhp when I get finished, I'm hoping that the 3" will be a little over specified for the application and that this will allow me have extra silencers etc without causing mad restrictions.

I want quiet, obviously it'll make some noise so I'm not looking for electric car quiet. But no booms allowed. I think I'll get souhan's to do it for me www.souhan.ie. They are magnaflow stockists but will cut & shape bits of pipe to complete the jigsaw. Has anybody any experience in how to make a quiet exhaust? I spoke to them before but didn't get around to asking them about the noise.

The car should be topping out at say 320bhp when I get finished, I'm hoping that the 3" will be a little over specified for the application and that this will allow me have extra silencers etc without causing mad restrictions.

Thanks in advance, am I

That's what i'm after! Just wondering if anybody tried to achieve the same thing before.

mine is 3inch turbo back, 2 boxes de-catted and was 95db at adi, its not boomy and sounds great but not too loud, with a cat on it should bring it down a bit more, I would go for the biggest back box you can fit in thats what I did there is some pics on my project thread.
I would make sure your diff mounts are in good shape if you are planning on 3inch over the diff too

they do press bends
don't use that on a performance exhaust
