Exhaust grumble?

[vk]

Hey guys, a really newbie question, but, is it possible to get a nice grumble from the exhaust on a tdi with dpf?
Looking for something basic, not necessarily loud, and still legal :S (insurance wise too).

I know it seems like a stupidly safe question, but I am interested

cheers

Removal of the rear pancake muffler helps a little, but the rear axle resonator is supposedly the main restriction after the DPF. Replace that with a decent straight through resonator and ditch the final big rear muff entirely and it will be a bit better, but diesels hardly ever sound sexy in 4 cylinder form, and the DPF is the best muffler you can get outside the turbo.

Soooo blunt, Aydan. You're completely right, though. Haha.

[vk]

haha yeh in this case im happy to accept a blunt answer, as i know i was shooting far off with this request haha!

[gldgti]

yeah, just trying to make it plain. the best noise you could get would be straight pipe, and very short, with no dpf. even then it wouldn't be as loud as a civic with a fart can exhaust. trying to make a big exhaust noise with a diesel that has a small turbo is like shovelling concrete with a garden fork.

We shall see....

Just so you know.... I'm stealing that.

haha well, i did say a subtle grumble, im not looking for that horrible loud noise the idiots put on their lancers, hell i dont want it to be loud, just a nice low gear grrrrrr

[gldgti]

I guess subtle can be pretty subjective.

I thought my old mk3 had a nice exhaust note...

full noise on the dyno but from infront....
VW Golf 3 AAZ TurboDiesel (not TDI) - YouTube

better one of the noise just after I put in the T3 turbo


I had 2.5" exhaust from the turbo back, with no cat, a short "hotdog" resonator about halfway and a straight through short rear muffler. even so, it was pretty darned quiet.

With the stock turbo it made a lot less noise with the same exhaust system. actually, that exhaust system with the stock turbo made no more noise than the stock exhaust, which was 2" - Cat, 1.75" the rest of the way with 2 mufflers.

I hope that helps.

you should have a look at this guy

VWVortex.com - Anyone have the APR Carbonio TDI intake for the Jetta MkVI?

just scroll down a little and play that video ..

Wow that actually sounds GOOD for a diesel!

I can only hope mine gets that sort of noise...

So im going to bump this back up, as I am once again interested in playing around with this, are there any new discoveries?
I was going to do a muffler delete, but apparently that is useless for any sound, I just want some sound, all I can hear is engine noise haha.

Getting a miltek catback.. that wont do anything without a downpipe? which involves bypassing DPF, which involves retuning for the dpf delete, which in turn, is illegal to have no dpf. haha

So are there any new discoveries?

I had a milltek cat-back exhaust on old Fabia VRS PD130 which was tuned - it didn't have a down-pipe suprisingly but EGR delete, custom code tune with a Forge FMIC and LWFW + everything else - it drove really well. Anyways - that had a really nice exhaust tone to it, which you could hear over the engine. I've got some old videos floating around on an old hard drive - I can try and find them to put them up if you want. I had a SEAT Leon FR with the CR 125kw Diesel engine - that sounded pretty nice too and that was stock.
