Feedback 4.2tdi backboxes removal findings! All good

[jonnypym123]

Hi Chris, just at the rear, cats and dpfs still in place(I'd love to get shot of them as well tbh), weighted the backboxes as well 14.5kg in total!

I've previously owned the D3 3.0tdi and had this done by the same company however there was an audible drone if I was honest (although tolerable) at 60mph this was over 2000rpm and overall was louder on idle.

The 4.2tdi though at 60mph no resonant drone at all, just a very faint increase in exhaust sound. If you plant the foot though you get a more aggressive tone and you can definitely tell it's a V8. It's almost Like Audi wanted to disguise that it was a V8 diesel, I think it sounds great. I would have thought getting a 4.2tdi that would be a down grade for you coming from a 6.0 w12 some beast that car! The cats and dpfs do a lot of muffling so I hear. Would an X pipe be of benefit do you reckon?

Hiya, iv had the 4.2tdi for a few years now. It has a remap and dpf gut. So it’s pretty quick. In fact I would go as far as saying it’s as quick as the w12. Only twice the fuel economy.

So initially I planned on keeping the w12, I only got it, but this has highlighted just how good the 4.2tdi is.

If I can sell on the w12 with no loss I’ll keep the tdi.

Alternatively if I can’t sell the w12 itl be going in for new flexis and an xpipe and I’ll be in exhaust noise heaven, albeit at the expense of fuelling the beast.

Sounds like you've got a dilemma there Chris, or just keep both
the w12 has a load more hp however I'm guessing here the weight and less torque put it on par roughly performance wise with the 4.2tdi, it's funny how these figures work.
I watched a video of someone recently getting the backboxes off their w12, very nice indeed and sounds unique, not many w12's flying about. again another Audi that was 'muted' to some degree set it free!
