This system is quieter than a R33 GTST decat and catback.

I'm also looking into this at the moment. From the (pretty extensive) research I've done into it, it seems the Milltek Resonated Y-Pipe is pretty quiet, although it is still louder than if it was coupled with a full system.

I'm trying to get hold of a Milltek or GTC Resonated Y-Pipe at the moment.

Can anyone shed some light as to how much the increase in drone is if just a NON-resonated Y-Pipe is fitted compared to standard?

Not trying to hi-jack the thread, it just saves creating a new one related to this.

I thought the milltek y pipe with standard cat back exhaust was the most boomiest. Read that somewhere due to the position of the y

The Milltek is the smallest bore at 78mm I believe. I would have thought this would have a factor in the overall noise and boomieness?

I have the Milltek resonated ypipe. Its not too loud really. Just a touch down on the non res milltek. You do still get some drone at a certain speed (70mph ish) normally going uphill for instance. As soon as you go faster the drone disappears.
