Down pipes and headers

[Gixerkid]

Exhaust is blowing on my K3 between the headers and collector,decided on some new downpipes and collector box and keeping my original end cans..
Seen the Delkeviks on ebay for £250...would i need to do anything to the fueling if I was to fit these...cheers

Would you NEED to?  No, you wouldn't.

But ideally you would get a dynotune done (do you have a power commander?) to get the best out of the new system.

I agree you should not have to, should be a straight swap, but if you do have a power commander fitted with a custom  map it might need tweaking

Cheers guys

As I was ready to buy the Delkevik down pipes and collector I had a change of heart and decided to get the full system.....should I go Delkevik or Black widow?

If your going for a full system akroprovic is the way to go

If you are keeping 4-2 I would go Delkevic, the stainless stays looking a little bit better than the Black Widow.

The Delkevic collector looks a bit better with the stainless trim not unlike the original collector.

Both are single skinned so the performance of both are about the same.

If your going for a full 4-1 or 4-2 you'll need a power commander and a remap .
