Hi all. I have an 03 Jetta Wagon TDI. I was wondering how I can get my turbo to sound louder. I hear other TDI's go by or just ideling and their turbo is a loud whistle, and my turbo is very quiet from day one. Any thoughts or ideas would be greatly appreciated. Also whats is a good 2.5 inch down pipe with a high flow cat that i can purchase? Thanks.

larger exhaust, and cone filter.
after i put the cone filter on mine, hitting 15 psi it sounds like a big whoosh and by 20 psi it sounds like a huge fan sucking in lots of air :twisted:
-
Hi there jtanguay, thanks for the reply. I just installed an AFE Stage 1 Cold Air Intake. The kit comes with a cone filter, but I didn't hear any increase in turbo sound, the only thing I noticed is that my car is a bit throatier while accelerating.

The other cars you have heard the turbos, were they driving by or were you in them? Can you hear the turbo from the outside of the cabin?

Hi Gary, thanks for the response. The other vehicles I have heard were either idleing or starting to drive away from being parked. My car is super quiet.

You shouldn't be hearing a turbo at idle
-
Generally, people try and make their cars quieter, and you want to make it louder LOL. I know one person that actually ran his intake into the cabin at one point in a quest to hear more turbo spool. It didn't work well with the windows closed, it'd pop your ears!

I can hear mine at idle, if the window is open. I have the stock air cleaner, but the exhauste is 2.5" from the turbo to the rear bumper. The "muffler" is a shortened Cherry Bomb glass pack (which is probably saturated with diesel gack by now).
If you want to hear the turbo, minimize or eliminate the muffler.
-
I couldn't hear my turbo at all until just recently. My exhaust broke just behind the cat. Sounds great now (slight rumble with a little turbo whistle) but my wife doesn't like the exhaust fumes when we are stopped. I think it should be a cologne. :lol:
-
Here is an example of the turbo sound that I would like. Does this mean I need to change my exhaust? Check this link out.

I don't hear much of a whistle from my 93 TD, all I really hear is a whooshing when I press the go pedal down.
-
Common 'mod' on the TDI Club was the muffler-ectomy, replacing the rear muffler with a straight pipe.
On my 97 I removed both mufflers (resonator?) and ran straight pipe from the cat back. I didn't find it louder or objectionable, but I could hear the turbo more.
When the exhaust was broken & open in front of the cat it was WAY louder.

Thats no muffler and big pipe. Guess what you have to do if you want that sound...
I have the stock air cleaner, but the exhauste is 2.5" from the turbo to the rear bumper. The "muffler" is a shortened Cherry Bomb glass pack (which is probably saturated with diesel gack by now). My car makes that sound.
The aircleaner mod will not do it.

Hey guys I have another question. Does the down pipe connect to the turbo? And also what is a good down pipe to get? I want one with a high flow cat on it. Thanks a bunch guys and sorry for all the questions I am a noob to all this. :?
-
yes the downpipe bolts right to the turbo. Talk to Dave at PP for a high flow one

you're running a turbo right??? what year vehicle??? pre '92 diesel doesn't require a cat :) after that i'm not too certain, but most likely if the vehicle came with a cat, they will be checking for one come emissions time :(

I have a 2003 Jetta Wagon TDI, with an AFE Stage 1 Cold Air Intake mod.

You can if it's a VNT with closed vanes. :twisted: I have a 2.5" exhaust and a normal muffler BTW.
-
I have performed a mufflerectomy, and I must say it sounds beautiful. And I can hear my turbo while ideling... :D And it sounds like a jet engine shutting down when I turn the car off. I am happy with the overall sound on the highway and street driving. I will post a video on youtube and post the link here. Thanks for the help guys!!
-
Let me ask you guys this, I like the sound of TDIs without a muffler and a bigger pipe and such. Does removing the muffler and such from a TD create the same effect? (Increase the turbo whistle?) Of course, a decent intake would be a must as well I suppose. So, what have you guys got a TD to sound like? Vids, sound clips?
-
I did a ghetto mufflerectomy to my 93 Jetta (actually the pipe after the cat broke off) and I still don't hear my turbo whistle unless I'm very close to the side of a building, then I can hear it a bit. I kinda like the exhaust sound, kinda sounds like a Honda with a fart can in a way. It's a bit too loud for my liking, if it were just a bit quieter it would be perfect. I'm thinking I'll replace both mufflers with some straight pipe and a cherry bomb.
-
Keep in mind broken exhaust under the car sounds significantly different (louder, tinnier, more resonance) than complete straight pipe to the back.
Also make sure you end with a turndown, both for sound and it keeps the soot off the back of the car, trust me :shock:

I'm in the same boat, in the same city... that makes two AAZs with pothole mufflerectomies in the Port City.
FWIW, it is much louder when it exits under the car; it echoes around. If you get it going straight through & out the back, it is much quieter.

Addautomotive and Infinitrium, I know in NB you have the annual safety inspection, same as in NS, but do your cars pass with no muffler? I want to do the same thing, but after looking into the rules surrounding inspections, the car must have a cat, resonator and a muffler. Just curious how it works in NB.

On the advice of my lawyer, I decline to answer that question.
Hypothetically, if it looked like it had all of those components, but they had been hollowed out, it *could* pass.
just sayin, yo.

:lol:
As for the hollowed out parts, the same hypothetical thought crossed my mind.

Dr. D's jetta had a 2.5" fron the turbo back, mandrel bent without a muffler. Especially when hot, you could clearly hear a very distinctive whistle out the pipe while it idled.
-
I have a 3'' mandrel bent Turbo back straight pipe on my 1.6l. TD. It's an awesome sound and I can definitely hear the Turbo at idle. On long trips I have to wear some ear plugs though 'cause I realized that I heard a ringing in my ears when I got home. Its not too loud in my opinion but everyone is different. I want to make the cold air intake with a cone filter down into the front there and that should really open it up even more. Right now I can totally notice a difference in performance especially when cruising on the highway. Its only really loud at certain RPM's like when your passing on the highway or hammering the throttle. I love it.

BIG STRAIGHT PIPE (at least 2.5) you WILL here turbo at idle
