Hi
So I understand that some people love dump valves for the noise alone and aren't too bothered with the slight performance gains from the reduction in turbo lag however I'm not a fan of the loud hiss, specially while driving through town or sainsburys car park.

So my question is....is there such a thing as a dump valve silencer / muffler or is there an alternative which gives you the benefit of a dump valve without the sound.

I'm installing the forge dump valve along with the Forge induction kit and at the very minimum a backbox delete and a Celtic Stage 1 remap.

Is this a pointless exercise and am I just getting old and should go and buy a Hyundai i10 for my daily commute !

Thanks

I'm 43 mate and still pi**ing about with my cars! I have a 1.2 tsi with remap backbox delete used to have dump valve and induction kit but took them off, no power gains just noise.

43 ! You old timer....at 42 I'm a mere youngster !

I love a project and I think it gets easier with age or more affordable at the very least.

So back box and remap is all I need then ?

The induction kit made very little noise and been an open cone filter heat soak is an issue, the dump valve was just for the noise but got annoying after a bit, back box delete sounds great and the remap has transformed it, I've got a vid on YouTube of the back box delete made it myself from a standard back box.

Im after the dump valve but Forge uk are out of stock for about the next month

The one on ebay from Germany is half the price I'd get that if I was after one

Couple of places on ebay selling them but I doubt they have stock.

So how easy was the back box job ? Did you weld the straight thru pipe yourself ?

Chopped the box open removed everything found a piece of pipe to fit job done 10 minutes to fit it as it had the original fixings.

The cheap dump valves iv seen on ebay aint forge i dont think? just cheaper reps? want to get black pipe and valve to keep it looking OEM under the bonnet. Exhaust isnt a bad idea as there isnt many aftermarket options for the 1.2 tsi

Out of interest is the back box easy to detach or did you cut and re - join.

I've not been under the car yet.

If you have the original system it needs cutting and a sleeve to join it which makes it easy to swap from one to another.
