WHAT IS A CLR ??
CLR stands for "center line radius" in this picture BELOW it measures from the outside edge of the elbow to the center = For example if this measurement was 75mm then the elbow in picture will be 75mm CLR.
WHAT IS THE DIFFERENCE BETWEEN THE FINISHES ON MY SINCO MANIFOLD
Pictures below are the x3 main finishes that we offer on our turbo manifolds.
Steamtube - Matte Black = This is our entry level finish, the manifold is beadblasted and VHT painted matte black. This is not a permanent coating and over time will start to rust, on the Evo manifolds where the manifold is directly under the bonnet vents they will rust a lot quicker because water leaks directly onto the manifold.
Stainless Edition = This finish is made from stainless steel 2.7mm thick (sch. 10) and is fully back purged and the welds have full penetration. We recommend this type of steel if race fuels are being used - E85 and Avgas etc. The manifold starts its life bead blasted and the flanges are painted matt black (they are mild steel), this is to keep the cost down and help prevent flange distortion (Stainless Edition finish before heat). Once the manifold goes through different heat cycles it will change colour starting off a blueish colour then moves to a bronze look like the picture below over time it will go more of a brown/black colour depending how hot it gets from different driving styles - i.e street or track.
Burn Edition = This finish is still made from 2.7mm thick (sch. 10 ) stainless steel but instead of the bead blasted matte finish like the stainless edition, the welds are left in a raw state. This is achieved by large gas coverage and high argon pressure when welding along with around 2-3 hours extra labour. This is the most expensive manifold available in our range and can be added to any manifold we fabricate.

SHOULD I HEATWRAP MY MANIFOLD?
CAN I RE-USE MY FACTORY EXHAUST MANIFOLD NUTS?
On left is a flange nut, these have a large face and can clash with the weld on a aftermarket manifold which will cause it to tighten up unevenly and cause the stud to bend or break, on the right is a standard locknut which has a smaller hex and will clear the welds of an aftermarket manifold.

WILL MY TWIN SCROLL TURBO WORK WITH MY SINGLE SCROLL MANIFOLD?
-You will not get any performance gains or quicker spool time if a single entry turbo is used with a twin scroll manifold
