Exhaust and Cats'

[TDi90]

and no i dont mean the pu$$y kind!

Quick question really i have an L Reg S2 Avant, if i go for a full Milltek system what bore size and does it need to be a cat back system? what are the differences between cat back and no cat? what are the cost implications of both. will it pass an MOT without one?

Kind Regards in advance

Miltek will be 2.75"

A cat back system bolts on behind the cats.

No cats will require a custom exhaust or replacement pipes where the cats would normally sit.

You will NOT pass an MOT without cats...

Without cats you need a very friendly mot guy or alot o hassle each year. Luckily my mate does my mot cat back does not include the cat section but should make it sound raspier

The Milltek still sounds much much better and a little louder than standard even with the cats still fitted.... BTDT
