Suss, do you think a resonator would help eliminate the droning sound I hear upon startup, when it's just warming up? I also suspect a better RMM would help with vibrations at idle.[/QUOTE]

I'm not sure, as the resonator tip can actually make things louder at the tip itself as opposed to the resonator being further up the piping at least according to what I've read about it.

A more rigid rear motor mount would only serve to transfer more vibration into the cabin, although if you don't go too agressive you can gain some help in preventing wheel or axle hop due to transmission and engine movement without creating too much resonant vibration as to damage anything.

KosKo425 Suss you always seem to have great info. I always feel like I am learning even if the things you talk about are so simple to you. Thanks boss.

What is a "resonator tip"??

A resonator exhaust tip can be considered as a cavity resonator in which the design causes the air to vibrate a certain way in a hollow cavity which produces a certain sound. They can be used in some systems to work with the muffler to reduce noise. But at the tip, a resonator exhaust tip will produce more noise versus a regular exhaust tip.

jimfocus I have seen in this and other exhaust threads refer to the the stock Mk III exhaust diameter as 2.25." I have checked mine several times and the pipe leading to the final muffler or "lunchbox" is 2" outside diameter. Am I wrong or does it go down to 2.00" at the end?

JeremiahD well they said they wouldn't recommend going over 2.5" on a 2.0L non-turbo.
bummer....man wish I could find something that sounds as good. maybe Borla? sigh.

JeremiahD Well I emailed them and they said there's no plans to make a non-ST system.

I'm waiting to hear back what they think about the ST system on my SE.

My main concern is the pipe diameter is 3" vs the 2.25" stock diameter or the common 2.5" aftermarket.

Anyone think it'll hurt the torque by goin 3"?

StingRay All of the hangar locations and routing are the same. The milltek exhaust sounds great, It'll be interesting to hear what it sounds like on an NA focus!
