I got fed up with the little rust piles every morning where I park, duly falling from the slightly rotted back box. So decided today was the day and had the 'mufflerectomy' done.

I've looked at the likes of Milltek and Blue Flame and they are very nice, however on a diesel I really don't see the need in fancy pipework, so in place of the rear box is now one straight piece of pipe, straight to a tailpipe.

I have left the CAT in place, as I didn't want a vast increase in noise and they are not particularly restrictive anyway.

As for noise - a nice burble on start up, but once running sounds pretty much like standard. It stays this way really until you give it the beans, especially above 3000rpm, then you get a lovely deep sound, most un-diesel like! Not stupidly loud at all. All for the very reasonable price of £65 and custom made within the hour

For those of you who are not sure about this, come and have a listen and then make your verdict! Video's on the way tomorrow.

Look how much room there is now!! and about 10kg lighter

Looks good

Looking forward to the video.

did this on a previous tdi be interesting to hear on a fab

Eagerly waiting for the video..!!! this will be the perfect set up for me if its not too obtrusive on sound!

Could you hover at 2~2.5k in the vid then boot it to see what it sounds like? thanks!!

Video's now done!

One done on my phone here:

This one when I got home on my digital camera:

Sounds Great not to loud

Wer did you get the green nurburgring sticker from

I got the sticker from the petrol station at the Ring. Straight after the cars first lap there of course!

that ll teach me lol

Sounds like my old one, until i took out the cat ;-)

have a click on the link in my signature, compares standard to back box removal :-)

As said on PM... sounds nice..!

I wonder what it will sound like if you have a bigger bore when you demuffle it (or decat). any guesses?

Probably not much different, its pretty deep as it is!

What diameter of pipe did you use?

Same diameter as the standard pipe, at a guess 2.25"?

Think its a 2", thinking of 2.5 if it'll make any difference, because I've heard that a few uprated it from cat back of 2.5 sounds lovely.

2.5" may sound lovely, but for a Fabia with say circa 170bhp, is that size really necessary? That is a whole different debate however.

If you were going from cat-back then you would need a lot more pipework. I just wanted to remove the back box, so a straight pipe was duly fitted in its place, also the most cost effective way of doing it.

does sound nice! was thinking of doing this also, might well do so now after hearing that! might make the 'tailpipe trim' a twin like the milltek for a change

then again on 2nd thoughts the oval does still look nice

That sounds great for what you paid, tempting, but I promised myself not to mod the vRS too much...

out of interest, who did the pipework?

out of interest, who did the pipework?

Jake

A company that is local to me called Powercraft Engineering, been around a fair few years but have just moved to a new bigger premises in Torquay.

I know this is an old post but does anyone know if I was to lose the back box and add a de-cat pipe would I encounter any problems with back pressure? and in turn a loss of performance?

I recently read the following article here which kind of makes sense but I was just wondering if anyone has any first hand experience of this mod? I am sure I seen a post last month where someone had a 'straight through' exhaust but cant find it.

Any help would be much appreciated.

Thanks, John
