103tsi wagon muffler upgrade cons

[R_LINE]

Hi all

I have a 2015 103tsi wagon. I just want more noise and was thinking of a muffler change.

My issue and question is if I change the muffler will that mess the fuel usage by much?

Nope, if anything would improve it slightly with less restriction - assuming you get a decent muffler that is!

What brand would you guys suggest is best? I normally just go to any exhaust shop and get them to bolt on a muffler. However most of the cars I've done work to were not turbo and was very basic.

Bang for buck plus low restriction and noise = Magnaflow.

You may need to do a little more than change the rear muffler. A friend with a Jetta completely removed the rear muffler and it was barely noticeable.

To get a decent increase you'll need to change the resonator. Going a resonator delete (replace with pipe) will likely be a little too much and cause unwanted resonance/noise in the cabin at cruising speeds.

Likely you'll need to change the resonator and rear muffler to get a good balance of noise at WOT and peace and quiet while cruising.

Check out this exhaust as an example of something you may look to replicate: http://www.awe-tuning.com/mk7-golf-s...-exhaust-suite

Good point, didn't realise doing the rear muff only on the petrol cars was minor as well, as it is with the diesels.

Yes good point but I really don't want too much noise. Just a bit more then stock. Once the resonator is gone or even replaced it will be loud...we'll too loud for the kids and wife.

I will try the muffler removal and if not happy I can try the resonator removal.

You can easily remove the muffler and run around the block without it to see if this gives the desired effect. Then it's simply refit some tips which an exhaust shop can easily fabricate up for you.

Take the muffler put and weld straight pipes? That would scream! Lol

There's often 2 separate components to the rear section of the exhaust system - a resonator and a muffler. I'm not sure what the set-up is on the 103TSI wagon, however it should be reasonably easy to take a look under (or stick your phone under and take a few shots).

You can unbolt the muffler and run it to see whether this gives the desired effect. Often the centre resonator is the thing that cuts the bulk of the noise so you may need to modify this to get a decent exhaust note (and DSG farts).

Most often times the exhaust systems on these cars is designed to eliminate any noise from the cabin so they're pretty much dead quiet and generally it's only engine noise you'll hear.

Just spoke to my friend who has done this mod on a 118TSI Jetta and confirmed he removed both the stock suitcase resonator and rear muffler and replaced with a single Magnaflow sports muffler to get quiet while cruising and decent noise on WOT.

I always did res delete and change muffler to a straight through muffler. This always ended with a great sound but also very loud. I use the wagon for family and just want to hear pops and bit more aggressive exhaust note. From what I read res delete is best way to go and leave the rest stock.

I also seen somewhere online with pictures of a resonator removed from an mk7 and it seemed like a straight through pipe. If that's the case...then the outer part of the stock resonator seems like it just absorbs all the noise and vibrations and that's all its for. I am mentioning this as I wouldn't want to do a res delete and cause any changes in milage or performance.

I read heaps that it doesn't change anything with just a res delete other then noise however I am yet to see dyno charts indicating no change. So it's all based on how the person feels.

I am on the fence on this atm.

Mod, always mod.

If you want to hear some noise you'll have to replace the stock resonator as that's the bit that cuts the noise. If you want a lot of noise go for a delete. If you want moderate level go for an oval or hotdog res.

CHEV from Liverpool exhaust stated... resonator removal will not make much of a difference in noise.

Is there anyone here with a tsi with only resonator removed with stock muffler?
