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

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.

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

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.
