103tsi wagon muffler upgrade cons

[tigger73]

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?

Can confirm the centre muffler (quite chunky) on a B8 A4 1.8T does most of the sound deadening, with the rear muffler not doing nearly as much. Perhaps is the same for PQ35?
PQ35 TDI only have a centre res, but PQ35 TSI seem to have two mufflers (like the B8 A4)

Okay so has anyone thought of getting a varex on their tsi? I'm keen on this option.

Varex can have issues with turbo cars due to amount of gas flow. Be careful.

What about armytrix systems? Same with them too?

Varex mufflers are designed as a one-size-fits-all system for every car - fit the muffler to your custom exhaust; Armytrix (asides needing a mortgage to buy one) are designed for the one car.
Same with Milltek; IPE; XForce; etc etc
