Benefits of a Tubular turbo manifold

[kcw 1]

A mate of mine spoke to a garage that specialise in custom exhaust, manifold and piping and they gave him a really good price for a custom manifold and downpipe for his 1.8t and it got me thinking . . . . . . Would it be worthwhile running a tubular manifold instead of the usual log type manifolds seen on more vr6 turbos?

Any info on this would be great,

Ken.

I don't think theres any room for a tubular manifold.. They take up quite alot of space and its a tight fit with the log type. The other thing is if you can get 500 bhp from the log type so whats the point in changing it

I'd have thought a custom one would take up less space as some of the log ones take up so much space, I could be wrong though.

ive got a custum one but not to happy im going to replace with a log type.

what is it avout your current manifold your not happy with?

Tubular manifolds pulse the turbo better, especially if it's an equal length one. The gains won't be massive, so most people stick to cast ones as they're cheaper and often stronger.

I think if I was to get one, id got for the dubpower one, looks abit more sturdy than say the raceland one and I think it has a flexi section aswell at the bottom so I would think that would minimise any stresses on it that would cause it to crack

The Dubpower manifold is for a N/A not a turbocharged one.

I'd be going to Meercat Exhausts for the manifold ( http://www.meercat-exhausts.com/ ) a very well known company with customers such as the late Colin McRae and Keith Cowie, the manifold would be an equal length item. I've been quoted around £800 do you think thats an alright price?

I'd consider paying £800 if they could demonstrate some tangible improvements over a cast manifold to justify the cost....and reassurance that it would fit perfectly. If not, stick to the tried and tested VR6 Turbo manifolds that are already available.
