new rear muffler Golf GTI 7.5 (2018)

[coasta007]

Hi all,

I'm in the process of looking for a new muffler for a Golf GTI 7.5 (201. I'd like a new rear muffler which sounds a bit louder than the original but to the point where it is too loud and annoying. I was looking at the TCR exhaust from Track Hack parts and it looks like the one to get. I saw a guy on youtube who installed it and sounded pretty good. Has anybody installed this exhaust? Is there an equal alternative as i'd prefter to buy from Austraia? Happy to pay bit more to support aussie sellers.

I read on the Track Hack website that it may need a slight modification due to pipe size which is no big deal. I can get the mod done at an exhaust place.

Cheers in advance

I assume you are talking about this part: GTI TCR Rear Muffler
– Track Hack Parts

They do certainly sound better than the stock exhaust, and you can remove it and sell it if you ever move the car on.

Unfortunately the wait time on this part sucks. The other possible option would be to get this one GTI Clubsport S muffler
– Track Hack Parts and have the tip spacing modified by the exhaust shop at the same time when you are having it fitted.

In my view the best sounding exhaust out there is a Milltek exhaust ..... I have it on the R, the A1 and the Up! at the moment.

GTI non-resonated (loudest) Milltek Sport Cat-Back - VW Golf GTI MK7.5, Non-Resonated, Polished Tips [SSXVW462] - Harding Performance

GTI resonated Milltek Sport Cat-Back - VW Golf GTI MK7.5, Resonated, Polished Tips [SSXVW457] - Harding Performance

On the Amarok I have an X-Force, which is OK, not super great, and on the 150TSI I have a Supersprint (which is for a GTI), which is also pretty good, just not Milltek good.

Well. I finally had the chance to install the track hack exhaust and I personally don't think it made much of a difference at all. A little louder for the crackle and pop but I think it was a total waste of money.

I think I should have bought something like this:

XFORCE - VW GOLF GTI MK7 & MK7.5 2013- 3" STAINLESS CAT BACK EXHAUST SYSTEM - MK7.5 GTI (2017+) - GTI/GTD - Volkswagen - Vehicles - SHOP BY

The other option is to first try the resonator delete pipe and see if that improves the sound.

The xforce exhaust sounds like garbage on the Mk7 GTI. Very loud and no refinement.

The resonator on the GTI is huge (its at least 60cm long). Get that either removed completely or replaced with a much smaller resonator and see how you like the sound.

Thanks for your reply.

Good to know about the x-force. I'll try the resonator see how it sounds. If it still sounds crap I'll look into the Milltek as Sharkie suggested.

It's hard to know what it will sound like without hearing them in real life.

Resonator delete sucks. Drone from 2500-3000rpm.

Thanks. I'll look into some exhaust systems. They all seem to have res deletes too

I just recently fitted the CTS exhaust. Its probably 20-30% louder on the outside but almost no difference from inside the car. Looks great and fitted up nicely. Note this is probably the most quiet aftermarket exhaust available for the GTI other than the OEM options, because the resonator and rear muffler are quite large. Some of the other brands run a smaller resonator (or no resonator) for more sound, but also probably more drone.

Thanks for the photos. It looks quite nice. I like the idea of it not being too much louder so I'll add that to the consideration list.

I bought and installed the GTI TCR Rear Muffler
– Track Hack Parts but that was a waste. As soon as I'm buying exhaust I'll try and sell the one I bought

The other option is now that I have installed the track hack exhaust the cars sound may improve if I get rid of the resonator? I want to make sure the next exhaust mod is a good one.

Yes I certainly considered the TCR muffler but decided against it for several reasons.

1) Looks - subjective of course. Its still an ugly OEM muffler and small exhaust tips
2) Only moderately louder than the stock muffler
3) Price vs sound/looks ratio

I knew that if I got the TCR muffler that I would still have to spend $200-300 to get some nice exhaust tips welded on. So that took the price up to say $800-900.

If you decide to remove it, im sure you will be able to sell it to someone else relatively easily for a small $ loss. Otherwise, try a resonator delete and see if you like it. It will certainly make it louder, it just depends on whether the tone stays nice and deep or goes tinny/farty, and whether there is much drone.

I did a resonator delete on my Mk7 (with the stock rear muffler) pics here and it certainly increased the volume and you could hear the crack of the DSG gear changes, with only minor drone. The issue for me was that the overall tone wasn't very nice, it became a bit tinny and farty in my opinion. I was going to have a small high quality resonator fitted to deepen the tone and reduce the fartyness but in the end, decided to go with a whole new exhaust so I got the looks along with the sound.

I have a video of the CTS exhaust on my old Mk6 GTI if you want to see it (i can link to the Youtube video) but havent done a video yet on my Mk7 GTI (although its very a similar sound).

Yes. I'll probably try the resonator delete and see how it goes.

I was looking at the x-force exhaust with the ability to adjust the valve position and also being able to have a certain valve position as you're coming home etc which is a great idea but not too keen if it sounds like garbage.

Any other exhausts with adjustable valve positions?
