It is much noisier on acceleration, especially if you plant your foot down, but cruising around 60 or 80, no extra noise what so ever, cruising freeway there is just a little of drone noise, if you have fan on 2 for example you can't hear it any more, so it's not much really. Down side is that I haven't noticed any gains from it (apart sounding like a hoon at takeoffs), like quicker spool of the turbo or power increase. But it seems to me that it increased my fuel consumption slightly, not sure tough.

OP you state that there was noticeable increase in power. Is this from exaust work only or did you have some pump tweaks done as well?

I only had the middle muffle replaced and the rear box removed. I have not had any tweaks done to the pump. Vehicle certainly runs better.

Karcraft have a bypass section for the centre muffler for $124
BA 2263
Might try this first and see if any improvement in up hill performance.

Just go to your exhaust shop, I was quoted $60 to remove the centre muffler and replace with straight pipe.

I will be getting it done as soon as I get my tax cheque back.

Had my front muffler on my Tdi surgically removed last week. 😊

How does it feel now? More power?

Is it much louder?

A little more noise. Not really noticeable IMHO. My Tdi isn't a quiet motor by any standardshttp://www.aulro.com/afvb/images/smilies/tongue.gif


My seat of the pants measuring device tells me the midrange and top end is a little stronger. As a bonus the floor where the muffler was is cooler too, I don't run carpet or underefelthttp://www.aulro.com/afvb/images/smilies/tongue.gif
