Title: TCR muffler on GTI performance
Post by: Gitteh on 04 April 2020, 11:10: Hi guys did anyone try a TCR muffler on his gti 7.5? Would be interesting to know if this improves the sound a bit, like the CS muffler does on the gti7.

Post by: McBoogle on 04 July 2020, 13:11: There seems to be a lot of positive chat about the CS muffler on the Mk7 so I would have expected more people to be trying this on the 7.5

Has anyone on here got one and is the website in the OP's post legit enough to buy from?

Post by: Paul70 on 11 July 2020, 19:43: Unfortunately Richard exhausts from MK7 and MK7.5 are not interchangeable. Another point is the CS exhaust has a reducer after the first resonator so actually has a smaller diameter pipe than the standard GTI! The rear box is more free flowing which makes it sound more grunty than the std MK7 GTI. The popular mod for MK7 GTI owners is to upgrade to the CSS rear box which fits straight to the standard GTI mid pipe and combined with the free flowing rear box helps differentiate the noise of the CSS from the CS. To be honest I am sure the CS pipe is still an upgrade for GTI owners so I am sure it will sell.

Post by: Maximusbiggus on 08 December 2020, 20:00: I ordered my TCR muffler from euro-parts.co.uk a few weeks back. I picked and paid for priority shipping (4day delivery) but they sent it by standard which took around 2 weeks or so. I had to demand a refund for the difference in postage which was €20 in the difference. It arrived without the box and was just wrapped in bubble wrap.

Anyway I had it fitted today and I'm very pleased with the results. It had a deeper, more throaty sound and the DSG farts are much louder. Inside the cabin it sounds as loud as if you have the soundaktor in sport mode. (I leave mine in eco and will soon turn off with OBDeleven). At a cruise the sound is the same as a stock GTI muffler. You can hear the difference at cold start, free revving the engine and of course when the engine is under load which is where it's most noticeable.

I was in a rush today but I managed to take a before and after video although I'll try take better ones of acceleration and cold start etc.

Here is a link to the video for anyone who is interested.

Post by: Pchende on 29 May 2022, 23:16: Does anyone have the correct part number for the Tcr backbox. Had a look on ECP and nothing came up. I have a 2018 Mk7.5 Gti which I want to upgrade.

Thanks in advance.

Post by: LSBristol on 01 June 2022, 15:39: It's 5G6253609ED.

Same code for either a TCR or Leon Cupra rear box as they are identical.

Post by: Watts on 02 June 2022, 10:18: The CSS back box is a popular upgrade for a MK7. Google it, plenty of chat about it and I'm sure there'll also be youtube videos too.

Post by: willni on 04 June 2022, 22:56: Is there a different clamp required or can we use the existing one? Planning on ordering from VW on monday.
Title: Re: TCR muffler on GTI performance
Post by: LSBristol on 08 June 2022, 22:48: Depends on year. My 2017 had same bore as the 2.5" TCR backbox so clamp 1K0253141AA works and is the VW standard way of replacing a backbox. However I believe sometime in 2018 they went to 2" bore and so you need to weld or get a reducer clamp.

There is no "existing" clamp as the stock exhaust needs cutting.
