Author Topic: 1.9 TDI Turbo Sound & 2.5" Down Pipe W/High Flow C (Read 17833 times)

WagonMan · « **on:** July 08, 2007, 03:06:27 pm »

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
