I'm posting for a friend who has a V plate 2.7T, he's had it for a while and is now thinking of tuning it for fast road use.
He's not wanting to go the top, just a exhaust and a map/chip for now.
The question is what exhaust, can he loose all the cats (retaining the oe main cats for mot time), or are the pre cat too hard to get too? Whats the best way to go on the mapping, will he better with a live mapping, will a pre made one have the same result? i.e would it be worth the extra money?
Any advice will be much appreciated :)
