Custom bent exhaust pipe angle and dimension checks - Factory sourcing support for stainless steel exhaust pipe

Fitment Guide decision points

Requirement and confirmation ledger
Decision point	Buyer / supplier question
Vehicle identity	Provide model year, make, model, engine and relevant routing notes. For a custom bent exhaust pipe, also record whether the buyer intends stock clearance or a stated modification. Installation torque stays with the workshop; this service only collects the purchasing questions.
Reference cross-check	Use OE or supplier reference as an inquiry input, not proof of authorization. Ask the supplier to map the quoted bend to the same diameter, wall thickness and end connection as the identified section. A different centerline radius can still be offered; it must appear on a deviation list.
Interface check	Confirm installed position, dimensions, flanges or slip ends, and included pieces. Request the bend angle, mandrel radius and whether the drawing measures overall length or developed length. Material grade should be copied from the drawing, not guessed from a photograph.
Alternative review	Ask the supplier to explain differences before approving substitutions. A straight stainless tube is not the same inquiry as a custom bent exhaust pipe. If a kit mixes bent and flex pieces, keep each line visible so sample approval cannot silently cover the wrong member. Treat new versus remanufactured supply, kit versus individual sections, and sample approval versus later production lots as separate decisions on the quote sheet.

Organize bend drawings with the flex pipe checklist when vibration sections are also quoted. Send unresolved checks through the procurement form.
