This is the TSR tubular manifold as used with our Garrett turbo kits for the 1.8t engine. These manifolds are constructed using 3mm 321 grade stainless steel. All flanges are lazer cut and the welds are back purged to ensure 100% penetration. Used in conjunction with other hardware we have achieved 500bhp from these manifolds. These tubular manifolds will work on almost all 1.8t vehicles using internally wastegated Garrett turbo's. Ceramic coating of these manifolds is also available please contact us for details.
