Pre-cat. . . . . REMOVED!

[18Edition30]

Its not an eggy smell really just fumes it seems.

Its worked a treat on the eddy anyways!

Finally got around to having mine removed today. Pleased to report faster turbo spooling as well as a nicer tone to it abd not sure if its just expectation but it really does feel quicker :D

Just what I reported 

There is definetly a few horse power in it, R-Tech nick said EGT's were lower and there was much less restriction in the exhaust 

[Kinks]

It makes sense in the respect that there is no disturbance to gas flow as it exits the turbo looking forward to testing on longer runs ;-)

Hi All,

Is this a mod that you would inform the insurance company about? (I mean would it be classed as a mod type thing, it's not aftermarket but is a modification to the standard system  )

Thanks

As it will increase power then you ought to. Although it's about the same gains as you get from using super unleaded over stock unleaded. Unless the insurance company understands what you are doing they may confuse it for removing the actual cat (illegal) so you may be best saying "modifying the downpipe on the exhaust to free up a few HP"

nah man, i wouldnt even mention it, its just a way to bump up your premiums for no apparent reason. most people dont even knw it there.

I agree with both of you above, would an insurance company check your pre-CAT in event of a crash?!?! (from the outside of the exhaust, you cannot even tell the difference...going on that, I am inclined not to mention it.

I know they do what they can to get out of paying a premium, but still!

[micaerin]

apart from the 4 bolts, is there anything else that needs undoing?

Have a look at this video mate:

Having a milltek cat back fitted on the 8th, reckon it's worth having them take the downpipe off and removing the pre-cat?

Simple answer - Yes !!!

Roughly 5 bhp more and a slightly deep tone and throttle response.

Does removing the pre cat add the petrol smell from lets say a de cat please?

[GrayMK5GTI]

You may get a slight smell from cold start, but that's it. Remember the main cat is still there. . .

I never noticed any strange smells  

Remember Milltek turbo back exhausts don't have pre-cats and you never hear people complaining of smells from those. It's just the same with this
