Designed in-house by Direnza engineers, our sports cat downpipes are a direct replacement for the stock catalytic converters. Engineered to not only improve power and torque but also throttle response on the S55 engine. 3" Diameter downpipes for maximum gas flow giving optimum performance increases Replaces the restrictive catalytic converter allowing you to gain more power from the S55 V6 engine TIG welded from T304 stainless steel for maximum strength and rust prevention Designed to be a direct replacement for the OEM catalytic converter Built in Flexi's reducing any strain on the exhaust system May require bypass software on vehicle ECU.

Our Civic FN2 Type-R 4-2-1 Tubular Race Exhaust Manifold & Downpipe replaces the restrictive standard cast iron manifold and improves exhaust gas flow thanks to its stainless steel, CAD-designed construction. It also replaces the restrictive catalytic converter, resulting in much improved throttle response and dyno-proven power gains. Features: Constructed from T304 stainless steel 4-2-1 design (offers greater mid range gains than a 4-1 design) 60mm Bore Collector 45mm Branch Diameter TIG welded Improved throttle response and gas flow Please note: sold for off road and track use only (will not pass an MOT test when fitted).

Our Race Spec manifolds are brand new to our product range and are constructed from 3mm thick T304 stainless steel in order to provide flawless reliability and robustness along with sizeable performance gains. Offering improved durability for high performance engines the mandrel bent, 3mm thick tubing allows for better exhaust gas flow in comparison to the OEM cast manifold. As a result turbo spool times are reduced and significant power gains will be attained. Features: Constructed from 3mm thick T304 stainless steel TIG welded Improved throttle response and gas flow Direct bolt-on on fitment Gaskets and Bolts included Fits Toyota Celica ST185 and MR2 Turbo Rev 1 & Rev 2 with 7 and 9 bolt manifold stud pattern models only.

Fitting a cat-back exhaust is a quick, easy and cost-effective way of releasing more power from your car's engine. This is due to the standard restrictive system being replaced with a more free-flowing system with a larger bore. Features: Manufactured from T304 stainless steel 3" bore with 4.5" tailpipe TIG welded, CNC machined flanges Gaskets and bolts included

Our Civic Type-R Race Manifold replaces the restrictive standard cast iron manifold and improves exhaust gas flow thanks to its stainless steel, CAD-designed construction. It also replaces the restrictive catalytic converter with a decat downpipe, resulting in much improved throttle response and dyno-proven power gains. Features: Constructed from T304 stainless steel 4-2-1 design (offers greater mid range gains than a 4-1 design) 2.5" bore collector TIG welded Improved throttle response and gas flow Direct bolt-on on fitment to standard or aftermarket backpipe (centre section) Please note: sold for off road and track use only (will not pass an MOT test when fitted). O2 spacer may need to be fitted to prevent engine warning light from being triggered.
