Hi there just looking for feedback on wether its worth changing my exhaust manifold on my 2002 octavia vrs, ive been looking at a t304 grade stainless steel manifold and here is the sellers spec :

This quality stainless steel manifold will replace your restrictive stock cast iron manifold, it is designed for optimum gasflow, so your exhaust gases will exit the turbo faster which in turn will increase your spool up speed and improve your throttle response.

Huge weight reduction over stock manifold

High quality T304 Stainless Steel

Mandrel bent polished Stainless Steel

T3 T3/4 Turbo Flange

35/38MM Wastegate flange

Direct bolt-on fitment

Includes gaskets

Improves torque and throttle response

Increase of upto 15BHP (depending on other mods)

The big question is will i have any problems by doing this? all feedback greatly recieved many thanks

but are you running a t3 or t4 turbo????

if your not then

it's just standard will that make a difference?

A stock turbo onto a T3/T4 flange? It would be like when you play that game as a baby - Put the shapes into the ball with hole shapes on it. The square never goes easily through the circle hole.

At very least, you will need a K03 flange on the manifold.

better to change the down pipe first as this seems to be the most restrictive part of the system

maybe do some research before you mod your car to understand what you actually have under the bonnet maybe a start buddy

the only good mannifolds on the market for k03 are ina mannifold and jbs mannifold

no real gains unless you have done all the other mods associated with the engine and exhaust.

all the best

Maybe that's why he is here? Maybe...

is jbs the only place that does stainless steel manifold for SERIOUSLY MODIFIED K03s turbo I've had loads of other work done….bigger injectors 4 bar regulator etc…..de-cated and centre box removed….the only thing i need is a modified manifold that fits a ko3s…..ive heard relentless do one?

Save your money, find a decent standard exhaust manifold and get this done:
