Mine quite droney, and both s2k nut's and Ang's sounded great last night. Besides, it's an excuse to mess around with it some more
What size is yours? I definitely don't want droning even if it just a weekend car. S2knut has 28mm if I remember correctly and Ang just 22 or 24mm??
Sorry, let me rephrase. I have an aftermarket Cobra system that is droney - I want to revert to OE with mod

Not got that far yet, need to source an exhaust first! More likely 28mm I think.

if you do it this way you can use full pipe diameter 65MM and change the sound by changing baffles

Toying with replacing the cobra **** on mine and reverting to OE. Will 04+ exhausts fit onto a pre facelift (03) ?
They will, but it looks weird. (Round hole vs oval pipes.) What's so bad about the exhaust on yours?

I think I will be going for 32mm from the noise S2k Nut's made. It sounds like a big engine Beemer.
Mine was 30mm ... I think !

Well I've just got back from Congleton after a very successful visit to see Ang and Ray at Daytona Autos. Chuffed to bits with the 'new' exhaust!

Ray fitted a 32mm pipe to mine and it sounds absolutely fantastic. I've driven most of the way back with the windows down, need to get the hard top off asap! From inside the car with the windows up it sounds 'subtle', with the windows down it sounds manic. Ray did a top job too, it looks almost OEM and you can't see it at all unless the car's up on the ramp and someone points it out. Ray even greased up the clutch ball joint 'while he was there' which I didn't even realise was a common issue.

Chilling at home now waiting to see if I go blind from watching Ray doing the welding , I'm sure I'll be fine.

And thanks for the tea Ang!

That looks intriguing oxhouser, makes me wonder if it would be possible to obtain a butterfly valve compact enough to fit there & be controlled from inside the car?

btw good on you for bringing the idea to us all in the first place, it's made a lot of people including myself very happy

top idea I'll bet you never thought it would get this big,

Ray's looked at using the BMW valve's, and the flange system with different size's,but the cost goes up and it moves away from being a quick cheap mod, just waiting to get a spare system to have a play with,

There's been quite a lot of posting on the US side of the forum about this thread.
