Tiguan Exhaust

[INASNT]

Never had a problem with IS38 and stock rear muffler. Quiet when you want it to be and loud when with a led foot

I think my problem is specific to my car and is due to the sympathetic vibration in the muffler. Didn't exist prior to the APR dump pipe and don't think it is air flow related as it happens at idle and low revs. I think a prior manufacturing fault has surfaced with the removal of resonator in the dump pipe. Don't think VW is likely to replace it under warranty though .

You can open and close valves by hand

Yes. I bought the exhaust without the motors so all that was left were the flap valves which can be turned by hand. Clockwise to open (on both sides) and there is just enough tightness in the actuator that I won't have to weld it down, they stay in any position I leave them in so with them fully open they stay there and I suspect that the exhaust air should keep them that way. I can also confirm that there is maybe, and I mean maybe, a 5% increase in sound so no resonator is needed, even with flaps open. At least on the little rice burner B cycle 2.0T in Canada. The piping is also smaller in diameter so had to step up when connecting the mid pipe to the R exhaust. Who knew

Very happy with it none the less. They lined up okay, had to watch them and be a "floater" in the shop but they were okay with it. I might have one of the tips pushed in maybe 1/4 inch but for now its pretty good. Need to clean up the tips now and wash the car but pretty happy all in all.

So we have got the same B-cycle motors, but in Europe we've got DSG7. Did you cut off resonator as well ? I did keep it and it's a little loduder about 2500-3000 RPM with valves open.
I can make fart i upshift- but from 1 to 2 only.
I do have motors for valves and trying to make some switch now.
I do have JB4 "piggyback" as well which gives me about 210KM .

I've had my exhaust issues sorted out now.
My setup has been CTS DP with CAT into stock Tiguan muffler. Horrible noise on cold start and light drone in 1st and some in 2nd just over the 2k rpm mark, and some in 7th gear over 2300rpm.
Then I went and got a Golf R Mk7.5 muffler installed and everything got worse. I should note that all valves are open.
Now I've had a Magnaflow resonator/muffler installed where the CAT was located, and the CAT has been moved up closer to the engine.
Now I have zero drone, and driving home last night with the stereo off I almost thought I was back to stock with everything.
I get a nice sound when dropping back the gears to pick up the revs quickly, and the car is nice and quiet in tunnels and underground parking lots.
I've yet to play with it a bit more to see if the DSG farts are still there but suspect they may just be more subtle now.
I'm just happy to have a high flowing exhaust system to match my Stage 3 mods.
I was quite surprised that a magnaflow part fit in when everyone else (both Tiguan and Golf owners) were getting hot dog/bottle style resonators from the likes of Lukey Performance and Vibrant, and still had a very small element of drone remaining.

I hope this helps anyone else that goes down the exhaust modification route.

Awesome news - really glad to hear that this sorted it. Magnaflow have a few resonators/mufflers - which part number did you get installed?

I gave up waiting for a Golf R exhaust to come on the market so ended up grabbing the XForce Varex muffler. It has a resonator where the normal Golf R resonator resides (which fits on the Tiggy), and was going to add an additional Lukey 12" long 3" hot dog resonator to my APR dump-pipe as well to reduce drone, but if a better MagnaFlow resonator also fits then . . . .

I didn't get the part number, sorry. I can see they have 3 different sizes of mufflers with 3in inlet and outlets but I'm not sure what the dimensions of the muffler are.

No problems - I'll work it out

It's 4x9 oval offset and 12in long.

Muffler mechanic said he had it for about 3 years on a shelf and was going to install a hot dog res when he remembered the magnaflow.
He claimed the hot dog would sit too low whereas the magna fits just right.
