How Much BHP Does 4-2-1 Manifold Add??

[c-h-r-i-s-w]

above you put a 4-2-1 manifold on a vtr roughly how much BHP would it add as i just read on ebay that it will add 12bhp is this true or not as i carnt really see this being true??
cheers:y:

[immense]

8bhp max tbh!

Nah you'll be lucky, maybe 5-6. Just uses more fuel, to get the best from mods you need a re-map. Car looks sweet btw

cheers m8, yh i fort it would add about 5bhp is it hard to fit a manifold? how much do garages and stuff charge roughly?
cheers:y:

Was quoted £30 by a garage to have a 4-2-1 manifold put on (me providing it ofcourse), not done it yet though - MOT reasons, I want to know how people get away with having one on when it comes around to getting it MOT'd :D

[benwh555]

Its not hard to fit, awkward but easy enough, if you feel up to it defo do it yaself. Garages charge bout £50, depends where u take it. But the more u try yourself the more u will learn. Get a haynes manual, they are crap yet good lol

most people just swap it over for MOT time

some just pay the guy a little more to pass it

how does it use more fuel doesnt it just let the gases escape faster ??

How would it affect the MOT can`t see that tbh.

on later models it removes the cat so should be an mot failer

could always fit the cat in the exhaust .. easier to change there than the manifold

The cat is on the manifold though, I was told it isn't even a possibility to fit a sports cat to Mk2 Saxo's.... :/

Well so longs as you have a cat in the system it shouldn't make any difference, it should still pass the MOT emmisions test!

Littleracer has a sports cat on his mk2 VTR. Pm him :)

[littleracer]

ok mk2 has cat in the mani.

if you get a mk1 mani it will de-cat for you.

if you want to stay road legal then yes you can fit a sports cat.

milltek do one which as far as iam aware is only available from cituning.

this is a 4 into 1 mani and the cat is still in the mani but the flow is increased dramaticly over a standard cat.

if you want any more details pm me

so why was my cat under the body of the car rather than in manifold?!

[Quick]

Its 01+ Vtr that has the cat in the manifold.
Vts of all years have it under the car!
