Extractors

[1991_Vn2nV]

You will definitely notice the difference, but dont expect something massive. But its a good gain.

k kool yea im not lookin for anythin massive just sumthin that will make it flow better, any gains in fuel?

 

[1991_Vn2nV]

Fuel economy should improve slightly... by like 0.1L maybe

ah k yea cause dad said he noticed a little bit of fuel difference when i got the exhaust put on, after extractors will be the VS CAI, have u got one of them on ur car 1991_Vn2nV

 

[1991_Vn2nV]

the VS CAI? yeah I do. Didnt make a difference to my economy, slight difference to performance. Nothing like the difference extractors made on my VL.

Are the pacemaker extractors for VNs all 2.25" outlet? I was having a look at their website cos I want to buy some extractors and fit them to a 2.5" exhaust. Can this be done or do I need to get a 2.25" zorst? What's everybody running in terms of exhaust size and extractor outlet size?

Theres an outlet on each side mate.

Which means theres 2x 2.25 inch pipes on the extractors. Thats why you have a Y piece which then joins them to the exhaust...

Di Fillipo make headers with a 2.5inch outlet, which is FAR too big for a V6. Even a 4.2L stroker would struggle to use all that.

Oh k thanks. I thought it ment the Y piece outlet was 2.25".
