Default Headers Query .. whats the best out there ?

Have a dilemma at the moment. Tried around 3 different manifold and wasn't impressed. Now looking to buy a FULL-Race (www.full-race.com) manifold. Its the 1.5scroll one. The price is dear but it looks like a work of art and the way the runners are look really interesting. Mainly I'm looking for an equal length and almost equal length manifold because I dont want to loose the sound of the car.

Any hints and tips of other manifold I can look at.

Thanks for help guys. Really need this sorted out asap because the manifold I have is really restricting most of my power and this is one of the few things I still have to sort out when it comes to the engine for the time being.

Regards,

Daniel

One of the best people you could ask for advice is ,Harvey on here.
If you do a search for his name you will find loads of info on headers etc

RCM seem to do the best ones albeit under different guises eg GT Spec etc. I've got them on mine & of course I'm not biased

I bought my tubular headers from Lateral Performance, same design as GT Spec / RCM. I also bought a GT spec up-pipe from Harvey Smith on here which help spool my MD321H turbo quicker by 300rpm.

I don't see any slip joints on there to allow for thermal expansion. Will they crack over time with hard abuse? Seem pricey too.

It might help if you start with model, year, turbo and relevant mods along with your current or predicted power when mods are finished.

Mods are all on the car already. Im running a rotated GT3076r at 1.8bar on 108ron racing fuel. Internals ARIAS custom pistons, Pauter Rods, slightly ported heads with stock valves, 272degree cams, Hydra Nemesis Standalone, FMIC, uprated injectors. Well theres to much to list to be honest and the manifold is the only let down on the car. If you wants some videos will gladly send some over. Car is used for daily driving and Malta Hillclimb and Pursuit Events.
