Disappointed, DP Exhaust, De-cat and full system

[Mo Arif]

Pretty disappointed with the results, I've just fitted a 3" turbo back downpipe into a de-cat which reduces to 2" and mates with a full cat-back system (mandrel bent) to a twin exit

1. it's not loud at all!?? it actually sounds the same as the standard system, bar a tiny winy bit louder, can hear my open air filter roaring more then the exhaust

2. to be truthfully honest, I can't notice any performance gains, early boost etc etc

Everything on the car is in good working order, healthy. What gives?

 

[james walker]

get it mapped to incorporate the free flowing dp and decat, you will see the performance gain then.

noise wise, has it a rear silencer?

 

[Seat Gooner]

i thought on a standard system it would show some gains as it can breath better

 

[james walker]

yes it will, allow ecu time to adapt.... maybe reset then go for a blast to allow to reset parameters.

stage 2 for best benefits though

 

[Mo Arif]

Reset? how? disconnect battery for 10 minuets?

 

[james walker]

yeah, well leave it 30.... go out n give it some beans for a while....

 

[LEE69]

So you only now have one back box and nothing else from the turbo back?

 

[Mo Arif]

silencer in the middle but surley a 3" downpipe and de-cat would make the exhaust burble a little, perhaps some pops, basically:

one of these (for a Leon Cupra instead):

and one of these:

so leave the battery disconnected for 30 minuets


Now before you lot go off on one, these a VERY high quality items, superb welds, build quality and finnish

 

[LEE69]

Silencer in the middle is your downfall if you want noise.

 

[Seat Gooner]

am i right in saying you can cut the silencer out lee

 

[LEE69]

Yeah i don't have the middle bit i used the centre section of the 1.9 diesel leon
Noise never increased either

 

[wayne lcr]

na i ant got a centre piece just the back box and mine sounds nice if i dont say so me self not to loud but enough to sound like theres power there

 

[Phillc]

I did the same as Lee , only got a different exhaust tone when i put the Cupra R back box on, then even more when i fitter the Piper Turbo back ( non resinated )

 

[SalSheikh]

R33f, i dont have a centre piece either and mines a nice burble mate. remove it and raplce with a straight pipe.

You should notice a hell of a difference to be honest, both me and Kenetic made 198bhp with standard map.

How come the catback system is 2"? thats less then standard?

 

[Mo Arif]

Sorry mate it's 2.5" typo,

Left the battery off for 30 minuets, took it to some nice b roads, gave it some, Actually have noticed the difference, and on the motorway today.

Happy now, but sound could be better.

 

[SalSheikh]

R33f, remove that middle pipe mate. should costs too much to do.

Give the exhaust a while to coke up, it will get louder

 

[Murdered LCR]

Defo get rid of the middle box that will make it sound loads better

 

[adam cupra 20vt]

I recently got rid of my centre box and it did make it a lot louder........not chavvy just a nice sound
