Hey guys, thanks for advice about the headlights. worked a treat! got another one to test your knowledge! lol. decatting my diesel, how will it affect it power wise? improve? make it worse?
Decat my diesel
- Thread starter Ibiza 130 tdi
- Start date
On TDIClub (complete boffins some of em!) its the general consensus that theyre not worth removing. They may halp the turbo spool up a nanosecond quicker but power will either be not affected or only 1% increase.
There was a test on there that proved the mufflers/silencers to be more restrictive than a CAT so people have them removed instead. Provides slightly quicker spool up and again perhaps a tiny power increase (but also releases ~20 KG's of weight from the car!!) - Do a search for "Mufflerectomy"
If your hardcore and dont care about legality - have a straight pipe, but that will start getting into 'loudish' territory!

Ok...
Cheers for the advise guys. I had my backbox changed last week. I have had a Powerflow back box put on. The back silencer is as the size of motorbike can now! But still, its not loud. There is a rumble around 2000rpm and if you flat it, but nothing special. I just wanted it decatting to get more noise...but obv if it was going to decrease performance I wouldn't have bothered...

Just remove the back box all together mate, you wont regret it.
T.Spark on here and i had them done at the same time. His is a twin and mine is a 6x4 Oval. Mine is quite a lot raspier and a little louder than his, whereas his you can hear the turbo a little more.

Mine had a 5x3" exhaust and was fine on the standard bumper.
Just get the FR rear valance, [only £20] so it has the exhaust cut out...

here's a link to my thread with vids clips of the muflerectomy, not the best quality but sould give you an idea of what no rear silencer sounds like
I have today had my exhaust replaced with a fully custom job (cat back) from powerflow, i had their smallest backbox fitted as i didnt want any MOT issues. So far i've noticed the turbo spools up quicker and the turbo whistle is much louder! Expecting it to take a while to loosen up and the real sound to show.
I would'nt be too put off by low statistical power gains, its things like throttle response and smoothened power delivery that really make a difference to how a car drives.
