that sounds very good songman, i will defo have that once my exhaust goes. does it sound better on your car than it would on a standard lcr though. and do you have any problems with poor fitment ie. does it rattle on anything.
I perhaps should have said - this is the sound of a
well thrashed Milltek system
!! - I don`t know how much `sound deadening` material remains in the back box after 30,000 miles of dyno runs/ acceleration runs/ top speed runs / as well as all the other `runs` - probably not much!
Stationary, at tickover, it is quite subdued in my opinion, but I have on occasions noticed some pedestrians stop and take a look
![[B)]](/forums/styles/seatcupra/oldforumsmileys/shades.gif "Cool [B)]")
In normal daily running - about town/70 mph motorway etc - It is not too obtrusive externally - inside the car there is a slight increase in `boominess` but I am use to it now and don`t notice it
All in all during normal use it remains at an acceptable decibel level and never aspires to the extremes of SPL known as `Rampant Corsaboy`
When the true `mentalness` prevails
- well then, the Decibel scale is of rather less use than the Richter scale in determining the effect upon the environment external to the car - inside you don`t notice `cause you`re too busy concentrating on hanging on and trying to point the thing in roughly the right direction!!!
The setup is noiser for sure with the IHI than it was with the KO4 - the standard exhaust manifold and turbo are quite restrictive and that in itself cuts the sound level down at source - there`s a lot more gas going down the tubes with the IHI - also you don`t get any `poppin` on the overrun with the standard kit.
The fit of the system is fine if you `persevere` - I say that because I did initially have some trouble with vibration on the overrun - I had this too, with another aftermarket system fitted to my previous car
I understand that there are clearance problems with the pipe run over the back axle if you try to go too large in diameter - the Milltek system is 2.75ins which is fine
The main source of vibration was clearance around the back box/heatshield - courage and the application of a large tyre lever eventually solved the
problem
I also have a VF Engineering `dogbone` mount fitted which reduces the fore/aft play of the engine block - this however is quite harsh and produces vibrations all of its own, so most folks will do better with just replacement/upgraded bushes in the standard VW mount.
One further point is to be aware of issues/fault codes with the second/post cat lambda probe, when engaging in changing exhausts and cats - it often being said that high flow cats will throw a fault code.
Hope this helps
