48.3 mm / 1.90 in Exhaust Merge Collector Cutting Template STL – 2-1 3-1 4-1 5-1 6-1 8-1 Metric Header Fabrication

About this model

Digital 3D printable Exhaust Merge Collector Pipe Cutting Template designed specifically for Ø48.3 mm / approximately 1.90 in round tubing. This model is part of the Europe Metric OD series and is intended for preparing equal-diameter exhaust runners before assembling multi-tube merge collectors, header collectors and custom exhaust manifold collector sections. TUBE OUTSIDE DIAMETER: Ø48.3 mm / approximately 1.90 in 48.3 mm = approximately 1.902 in. The exact reference dimension for this model is Ø48.3 mm outside diameter. Ø48.3 mm is an important European pipe outside diameter commonly associated with EN / DN40 dimensions. SUPPORTED COLLECTOR CONFIGURATIONS: - 2 into 1 / 2-1 - 3 into 1 / 3-1 - 4 into 1 / 4-1 - 5 into 1 / 5-1 - 6 into 1 / 6-1 - 8 into 1 / 8-1 The printed template slides directly onto Ø48.3 mm tubing and provides a reusable physical reference for marking the cutting geometry required to prepare multiple tubes for a merge collector. The same template can be used for several multi-into-one collector configurations, making it useful for repeated fabrication work without manually calculating and laying out every runner cut. HOW TO USE: 1. Measure the actual outside diameter of the tubing and confirm Ø48.3 mm. 2. Slide the printed template onto the runner tube. 3. Select the required collector configuration. 4. Position and orient the template correctly. 5. Trace the required cutting geometry with a marker. 6. Remove the printed template before cutting. 7. Cut the tube using an angle grinder, bandsaw, hacksaw or another suitable metal-cutting tool. 8. Deburr and finish the cut surfaces. 9. Repeat the process for all required runners. 10. Rotate and arrange the prepared runners into the required collector configuration. 11. Check the mating surfaces. 12. Tack weld the collector assembly. 13. Verify symmetry, alignment and outlet geometry. 14. Complete the final welding only after confirming the complete collector shape. SUITABLE FOR: - Exhaust merge collectors - Header collectors - Custom exhaust manifolds - Naturally aspirated headers - Turbo manifolds - Motorsport exhaust fabrication - Racing headers - Stainless steel manifolds - Mild steel manifolds - Motorcycle exhaust fabrication - Custom automotive fabrication - Prototype exhaust systems - TIG welding - MIG welding - General tube fabrication Ø48.3 mm tubing is widely relevant to European metric and EN pipe fabrication and can be used for exhaust runners, collector assemblies and other custom tubular projects. This template is especially useful when several equal-size Ø48.3 mm runners need to converge into a single collector outlet. EUROPE METRIC OD SERIES This version is designed specifically for: Ø48.3 mm actual outside diameter tubing. The imperial value is included as an approximate international reference. IMPORTANT SIZE NOTE: Ø48.3 mm is a separate model from nearby sizes including: - Ø47.625 mm / 1-7/8 in Inch OD - Ø48.0 mm Metric OD - Ø48.26 mm NPS 1-1/2 pipe - Ø48.6 mm JIS 40A pipe These dimensions are close but belong to different tube standards and market series. Always select the template corresponding to the actual tubing OD and intended standard. DIGITAL PRODUCT ONLY. This listing contains a digital STL file for 3D printing. No physical template, metal tubing, finished collector, exhaust manifold, welding equipment or cutting tools are included. IMPORTANT: Always measure the real outside diameter of your tubing before printing. Tube manufacturing tolerances, weld seams, coatings, filament shrinkage and 3D printer dimensional calibration can affect template fit. The printed part is a MARKING AND FABRICATION GUIDE only. Remove the plastic template before cutting, grinding or welding. Always test-fit the prepared runners and verify the complete merge collector geometry before final welding.
