What did you do to your Tiguan today?

[Suffolk]

I had it on my car for a couple of month, I had to remove it because my wife didn't like the noise. I didn't have any issues with it.

I have used both the GFB DV+ and CTS diverter valve and my understanding is that they are designed to hold boost better than stock, unlike a blow off valve the air is recirculated in the intake manifold rather than released into he atmosphere. So it is strange that the Forge DV is creating a new 'noise'..........

I currently have a GFB DV also. You may need to see the following video to see how the Forge DV works, enjoy

Thanks Suffolk, best explanatory video for DV vs BoV. This confirms my earlier post that a DV recirculates air into the intake manifold vs a BoV which releases air into the atmosphere producing the additional "noise." See 9.10 for where the ECS explains the difference.

Just installed a tow strap from EPR today, it was extremely fiddly but with the knowledge gained it wouldn't be a big job next time

Did a muffler delete today but not 100% happy with the sound.
Too much drone and getting a loud high pitch squealing noise on WOT.
Going to return and find out if there is a leak. Also going to put a sports muffler on and maybe a hotdog resonator.
Has anyone had any similar experience to share?

I'm pretty sure team_v went the rear muffler delete and then put it back on due to drone.

I ended up with a sports muffler and hotdog resonator and it had a decent amount of noise on WOT but was still reasonably quiet at cruising speeds. Plus DSG pops

What sports muffler and hot dog resonator brand did you go with?

Any videos or sound clips?
Really want DSG pops. Muffler delete did it but only on 2000-3000 rpm with 1st and 2nd gear. Wasn't noticeable like what gti's produce.

Well.....it IS a VW after all so a breakdown is inevitable. [emoji12]

Touche...

Probably best clip with just the rear sports muffler and no resonator (cold start):

Here's a launch after the resonator was fitted:

And a pic of the exhaust showing muffler and hotdog resonator. Not sure of the brand of each, however the suitcase muffler was through HM Headers in Melbourne and the hotdog muffler was installed by my local exhaust shop:

Thanks for the help tigger73.
Got rid of the muffler delete and went catback exhaust with 3inch piping.
Got a sports muffler and hotdog resonator.
Finally able to get DSG pops.
A bit too loud for my liking still.
Should I be change the resonator or rear muffler? Or add another resonator if space permits?

Just drive it for 1,500-2,000km and it will tone down. You have to wait until the exhaust soots up before you know what it's going to be like long term. I wouldn't go making changes unless it's way too loud.
